Formulary Exception: How to Get a Non-Formulary Drug Covered
Your drug isn't on formulary — but that doesn't mean it can't be covered. Here's exactly how to request a formulary exception and what to include to give yourself the strongest shot.

Your medication worked. Your doctor prescribed it. And now your insurance says it's not covered.

Learning that your insurance plan doesn't cover your treatment is frustrating, and often leaves folks with a lot of questions. Whether you got a letter in the mail or a message from your doctor's office, you're probably wondering – what in the world is a formulary, and what do I do if my drug isn't on it?

A formulary is the list of drugs that are covered by your insurance plan. But what most people don't know is that even if your treatment isn't on the list, you can still get covered. Most plans are required to maintain a formulary exception process, and if that's denied, you have the right to appeal.

And when a formulary exception is granted, it means your insurance has to cover your treatment again – even if it's not on their official list.

Let's break down what to do if your med is "not on formulary", and how to get it covered again.

How to get a non-formulary drug covered: Quick answer

To get a non-formulary drug covered, request a formulary exception from your plan. Start by confirming why you were denied: Check your plan's formulary and get the denial reason in writing. Then, submit the exception request to your insurance. Ask your doctor for a letter of medical necessity to support your request, and clearly document any failed alternatives or other reasons why you need the exception. If your exception is denied, you have the right to appeal – and appeals supported by strong clinical evidence, legal citations, and a clear patient narrative succeed far more often than most people realize.

What Is a Formulary – and What Does "Not on Formulary" Mean?

A formulary or drug list is your insurance plan's list of approved medications. It's organized into tiers – typically ranging from low-cost generics to high-cost specialty drugs – and it determines what your plan will cover and at what cost.

When your drug is "not on formulary," it means your plan has decided not to include it on that list. When it's "non-preferred," it means they'll technically cover it, but only after you've jumped through additional hoops (usually trying cheaper alternatives first).

Here's the part most people don't realize: formularies aren't just about if a medication works. They're heavily influenced by rebate deals between insurers, pharmacy benefit managers (PBMs), and drug manufacturers. A drug can be clinically effective, widely prescribed, and still get dropped from a formulary due to behind-the-scenes business deals. The medication didn't change. The science didn't change. But the business math did.

That distinction matters, because it means a formulary exclusion is often a financial decision dressed up as a medical policy – and financial decisions can be challenged.

How Formulary Denials Happen

If you're reading this, it's probably because you got a letter, a notification, or a phone call that tells you your medication isn't covered. These notifications can come in different forms, and what you should do next depends on what you're dealing with. Find the one below that sounds like you.

Patients get notified about formulary changes in a variety of ways – from upcoming change notices to formal denials that cite formulary alternatives.

You got a letter saying your medication is being removed from formulary. This is a prospective formulary change – your plan is dropping the drug on a future date. Insurers are supposed to send this 60 days in advance (though the notice is mailed 60 days ahead, that doesn't mean it arrives that early). You only get this notice if the insurer knows you're currently filling the medication. If you just switched plans or are newly prescribed the drug, you won't be notified.

You got a denial notification in your pharmacy or insurance app. A short message in your CVS, Walgreens, or insurer app telling you the claim was denied. These notifications are a starting point, but they're often frustratingly incomplete – a brief description without the full denial reason, the policy they applied, or your appeal rights. Don't assume this is the whole story.

You got a formal denial letter in the mail. This is the letter with the specific denial reason and information about your rights. It's the most complete notification – but it can take two to four weeks to arrive after the initial denial. That's weeks you could be using to prepare.

Your doctor or pharmacist told you it's not covered. Sometimes your provider checks your benefits, sees the drug isn't on formulary, and tells you they're going to switch you to something else. In this scenario, you may not receive a formal denial at all. If this happens, it's worth having a conversation with your provider about whether you want to switch, because you do have other options.

Regardless of how you found out: call your insurer and request the full documentation – the exact denial reason, the coverage policy they applied, and your appeal rights and process. Ask them to send it the fastest way possible: through your online portal, faxed to your provider who can share it with you, or emailed directly. Don't wait for paperwork to arrive on its own timeline. And don't wait for the formal denial letter to start preparing – you can begin gathering documents and building your case as soon as you know there's a problem.

The Biggest Misconception: "Not Covered" Doesn't Mean Final

The most common reaction when patients hear "not on formulary" is to assume there's nothing they can do. That it's a final decision — and that "not covered" means "can never be covered."

It's not. And this is perhaps the single most important thing to understand about the entire process.

Even many providers will tell patients "it's not covered, there's nothing we can do" – and that's simply not accurate. You have a legal right to request a formulary exception, and if that's denied, you have additional appeal rights including independent external review. Insurance companies benefit enormously from people believing that "not covered" is the end of the road. For the vast majority of denial types, it's actually the beginning.

A note on weight loss medications: If your medication is excluded specifically because your plan doesn't cover drugs for weight loss as a category, that's a plan exclusion – which is different from a formulary exclusion and significantly harder to fight. If you're in this situation, we've got a whole guide to plan exclusions here.

Formulary Exception vs. Prior Authorization: What's The Difference?

In many cases, you can't formally request an exception until there's a written denial. The PA is often what generates that denial.

What Is a Prior Authorization (PA)?

A prior authorization is when your insurer requires your doctor to request approval before a medication will be covered. Your doctor submits clinical documentation, and the insurer decides whether the drug meets the plan's coverage criteria.

A medication can be on the formulary and still require a PA. Many plans apply PA requirements to brand-name, specialty, or high-cost drugs.

If a drug is non-formulary (not on the approved drug list), coverage usually requires an exception review — and in most plans, that request is submitted through the same PA system. That's why the terms often get confused.

What is a Formulary or Medical Exception?

A formulary exception is a formal request to cover a drug that is not included on your plan's formulary. You're asking the insurer to make an exception based on medical necessity, failure of covered alternatives, lack of equivalent options, or risk of harm from switching.

How the process actually works

In many cases, you can't formally request an exception until there's a written denial. The PA is often what generates that denial.

If your current medication is removed:
Benefits are checked → A PA is required or the drug is non-formulary → A PA is submitted → The PA is denied → You request a formulary exception and/or file an appeal

If you're prescribed a new non-formulary medication:
The prescription is sent to the pharmacy → You're told it's not covered or needs a PA → A PA is submitted → The PA is denied → You request a formulary exception and/or file an appeal

If you're forced to switch and the new medication isn't working:
Your insurer requires you to switch to a covered alternative → You try the new medication → It's ineffective, causes side effects, or worsens your condition → Your provider submits a PA to return to the original medication → The PA is denied → You request a formulary exception and/or file an appeal

Why this matters: In all three situations, the prior authorization often generates the written denial that unlocks your right to appeal.

Insurance rules are layered and technical. Claimable helps you move from denial to action — so treatment decisions stay where they belong: between you and your doctor.

How to Request a Formulary Exception

Make sure you have an active denial

Before you can pursue a formulary exception, you generally need a current, documented denial.

If you've received notice that your formulary is changing on a future date, don't wait and hope it resolves itself. Ask your provider to submit a new prior authorization on the first day the change takes effect. Once the change is active, any prior approval is typically no longer valid — even if it feels like it should be.

Your provider may not automatically resubmit a PA, but they can. Just ask.

Once that new PA is denied, you have a clean, current denial to challenge.

Choose your pathway

There are two ways to pursue a formulary exception, and you can actually do both at the same time:

The provider pathway: Your doctor submits a formulary or medical exception request to your insurer, focused on clinical justification. This may include documentation showing that covered alternatives were ineffective (therapeutic failure), alternatives caused adverse effects (intolerance), and/or alternatives are unsafe due to contraindications or FDA warnings. This pathway centers on proving medical necessity.

The patient appeal pathway: You submit a formal patient appeal directly to your health plan. This is the pathway you control immediately. It allows you to go beyond clinical arguments and include how the denial personally impacts your health, life and finances and call out specific legal protections and policy inconsistencies that show your care should be covered. You can also attach your provider's medical justification.

You don't have to choose just one. Pursuing both pathways can increase your chances — think of it as "more shots on goal." If you're already researching on your own, we recommend starting a patient appeal – it puts more tools at your disposal and doesn't depend on your provider's timeline or capacity. Appeals are strongest when patients and providers work together.

A note on "formulary exception forms"

If you've been searching for a standard "formulary exception form," you're not alone. Most exception forms are designed for providers, not patients. And even when they exist, they often don't leave room to fully present your case — including clinical evidence, legal arguments, and policy support.

Don't get stuck form-hunting. You can submit a formal appeal letter directly to your plan's appeals department — or use Claimable to generate and submit the request for you. If your insurer needs additional clinical documentation, they can request it directly from your provider during the review process.

Use the right language

Here's what most guides won't tell you: the specific language you use can determine whether your request is properly categorized or quietly buried. Insurers route requests based on trigger words. If you don't explicitly ask for a "formulary exception" and state why you qualify, your request may be miscategorized as a general inquiry – which means longer timelines, less scrutiny, or it simply being ignored.

You qualify for a formulary exception under three main categories:

  • Therapeutic failure – the formulary alternatives were tried and either never worked or stopped working over time. Be specific: name each medication, how long you were on it, and what happened.
  • Adverse events – you experienced side effects that made the formulary alternatives intolerable. This includes reactions that led to hospitalization, allergic responses, or side effects that significantly impacted your quality of life.
  • Clinical contraindication – the formulary alternatives are medically inappropriate for you. This could be due to drug interactions, an FDA black box warning for your specific situation, or a co-existing condition that makes the alternative unsafe.

State your category clearly and explicitly in your request. Don't make them guess.

One critical timeline to know: under federal rules, insurers generally must provide expedited review within 72 hours for urgent requests and standard review within approximately 15 days for pre-service appeals – far faster than the standard 30-day review window for regular appeals.

But here's the catch: if you don't specifically request an expedited review and explain why your situation is urgent, many insurers will default to the standard timeline. If your health could seriously worsen by waiting, you have the right to request that 72-hour review. Put it in writing. At the very top of your appeal letter, write: EXPEDITED REVIEW REQUESTED (72 HOURS). Make sure it's impossible to miss.

Also double-check whether your insurer has a separate fax number or submission process for expedited appeals — they often do.

Know your rights, and state them clearly. Timelines vary by plan type, so always confirm your plan's specific rules.

General reference points for response timelines. Often in practice, these take a few more days – but this is a good rule of thumb. Timelines can vary by plan type, so it's always a good idea to double check which timelines apply to you.

Know Your Plan Type

Appeal rights and timelines can vary depending on your plan type and sponsor.

If you work for a large employer, you're likely on a self-funded plan, meaning your employer ultimately pays claims and serves as the plan fiduciary under the Employee Retirement Income Security Act (ERISA). In these cases, your appeal can reference your employer's duty to act in the best interests of employees.

Fully insured employer plans are generally subject to ERISA, the Affordable Care Act (ACA), and applicable state insurance regulations. Individual and exchange plans typically follow ACA and state rules. Federal and state employee plans, Medicare, and Medicaid each have their own appeal procedures and timelines.

Always review your plan documents — often called a Summary Plan Description (SPD), Evidence or Certificate of Coverage (EOC), plan brochure, or member handbook — to confirm the specific rules for formulary exceptions that apply to you.

What to Include in Your Formulary Exception Letter

A request that says "I need this medication" isn't enough. The ones that succeed build a structured case with specific, documented evidence. Here's what your letter should include:

The letter itself

Subject line: Request for formulary exception / appeal of non-formulary denial for [Drug Name]

Identify the denial. Your name, member ID (on your insurance card), date of denial, and the medication you were denied.

State what you're requesting. Be explicit: "I am requesting a formulary exception for [drug name], and coverage at the medically necessary level." Use the words "formulary exception." Don't leave room for miscategorization.

Explain why you need this specific drug. This is the core of your case:

  • Your diagnosis and its severity, supported by test results or doctor's notes
  • Why this drug is appropriate for your condition, citing clinical studies that support its effectiveness
  • Why alternatives failed or are unsafe – name each one, how long you tried it, and what happened. If any alternatives carry warnings or contraindications for your situation, state that clearly.
  • If you're stable on the drug: explain the improvement you've experienced and why switching creates risk – relapse, ER visits, loss of function, need for additional treatments. Spell out the real-world consequences rather than keeping it abstract.

Add legal and policy support. Reference applicable laws and protections – many states have laws against non-medical switching, and federal protections may apply depending on your plan type. If you're currently taking the medication and losing coverage could cause a gap in care, note this clearly and mark your request as "URGENT: Expedited review requested" to invoke the 72-hour review timeline.

Close with your ask and a list of supporting documents included.

And if you need help putting all of this together – that's where Claimable comes in. You answer some questions about the denial, your medical history, and personal story, and we get to work researching all the right studies, laws, and other evidence you need to build a strong appeal. Then, we fax and mail it for you. Our job is to translate your experience into a lawyer-level appeal letter, and give you the best possible chance of getting that exception approved.

A strong, well-structured appeal goes beyond clinical justification to make your case for coverage.

The supporting documents (include as many as you have)

  • Your denial documentation (notice letter, denial letter, portal screenshot or app screenshot)
  • A Letter of Medical Necessity or the Medical Exception Form from your doctor
  • A clear list of previously tried alternatives (drug name, dates, outcome, side effects)
  • Relevant clinical notes from your medical records
  • Any clinical studies supporting your medication for your condition
  • A copy of your plan's rules, called a Summary Plan Description (SPD), Evidence or Certificate of Coverage (EOC), plan brochure, or member handbook

Where to find your clinical documentation: Your provider's patient portal is your best starting point (e.g., My Chart). Look for:

  • Your medication list – showing what you've tried and why you stopped each one
  • Your allergy list – documenting adverse reactions to specific drugs
  • Visit notes from appointments where you and your provider discussed treatment decisions

If you can't find what you need in your portal, ask your provider directly for the clinical notes that document your treatment history – specifically the notes showing why alternatives failed or aren't appropriate for you.

Getting the Letter of Medical Necessity: If your provider is busy (and they always are), send them a template and specific talking points (we have one available here). Follow up – a single email that goes unanswered isn't enough when your coverage is on the line.

Common Mistakes That Waste Time or Hurt Your Request

Trying to resolve things by phone. Calling to check on the status of your request? Good to do, and can actually help – insurers have been known to claim they never received something until you provide tracking details (and then suddenly, they find it!). But don't try to appeal or negotiate a coverage decision over the phone. You don't want a low-level phone representative making decisions about your care. You want a written record, a formal process, and a qualified reviewer examining your evidence. Get everything in writing, ask them to send documentation of anything you discuss over the phone, and confirm everything they tell you in writing.

Filing a complaint with the wrong regulator. Many patients spend weeks drafting a complaint to their state Department of Insurance – only to learn that their plan is regulated at the federal level, where the state DOI has no jurisdiction. The majority of employer-sponsored plans are governed by federal law (ERISA), not state law. Before you spend time on a regulatory complaint, verify who actually regulates your plan. Your denial letter should include this information, or you can call your insurer and ask specifically: "Who handles external appeals for my plan?"

Not asserting your timeline rights. As mentioned above, formulary exceptions have faster review requirements than standard appeals. If you don't explicitly cite these timelines in your request, insurers have little incentive to prioritize it.

If Your Formulary Is Changing, Here's How to Prepare

If you've received notice that your medication is being removed from the formulary on a future date, don't wait for that date to arrive to take action.

  • Get the longest supply you can now. If you're eligible for a 90-day fill, request it before the change takes effect. This gives you a buffer while you work through the exception and appeal process.
  • Request a continuity of care exception. You can request a continuity of care exception to maintain coverage while your appeal is pending. Whether it is granted depends on your plan's rules, but it is absolutely worth asking.
  • Have your provider file a new prior authorization on the first day the change takes effect. Your existing PA is effectively expired on the date the formulary change goes into effect, even though it shouldn't be. Your provider may not automatically resubmit a PA — but they can. Just ask. Once that new PA is denied, you have an active, current denial to appeal.
  • Prepare your documentation in advance. Gather your clinical records, research the clinical evidence for your medication (or use Claimable to do the heavy lifting for you), and draft your personal statement. You don't want to be scrambling after you've been denied – you want to be ready to file immediately.

Don't Wait for the Denial Letter: Start Taking Action Immediately

You don't need to wait for the formal denial letter in the mail to start building your case. As soon as you know there's a problem – whether it's an app notification, a call from your pharmacist, or your doctor telling you they're switching your medication – make two phone calls.

Call your provider's office. Tell them you've been denied and you plan to challenge it. Ask for copies of the clinical notes that support your need for this medication – your treatment history, documentation of failed alternatives, and any relevant test results. Ask them to send it as quickly as possible.

Call your insurer. Request all documentation used to make the decision. Your denial letter (when it arrives) will likely include language stating you can request this – but you have to ask. Request:

  • Clinical review notes
  • Internal medical policies applied to your case
  • Guidelines, criteria, or standards they relied on
  • The name, credentials, and specialty of the reviewer
  • Documentation of any automated systems or algorithms involved in the decision

Also file a separate claim file request – a formal request for your complete case file. This can take up to 30 days to fulfill (and insurers often don't comply unless you follow up), so getting it started immediately is smart. Consider sending it as a standalone request rather than bundling it with your appeal, since it may go to a different department.

Submit Your Appeal and Follow Up

Where to send it

Start with your denial letter or portal notice – it usually lists the appeals address, fax number, or portal upload path. If you don't see it, call the member services number on your insurance card and ask: "Where do I submit a member/patient appeal for a non-formulary denial?"

Some plans allow you to submit appeals through your online portal, which gives you a digital confirmation. If you fax, save the transmission receipt. If you mail, use certified mail with tracking.

When to follow up

If your appeal was faxed and the situation is urgent, call the next day to confirm they received it. If they say they don't have it, provide your fax confirmation details – they often "find" it once you can prove it was sent.

If your appeal was mailed, allow two to four weeks for delivery and processing. Once tracking shows it's delivered, start calling to confirm it's been logged and assigned for review.

Keep a simple log of every interaction: date, time, who you spoke with, what they said, and any reference numbers. This paper trail matters if you need to escalate.

What to Do If Your Formulary Exception Is Denied

A denied formulary exception is not the end. Your appeal rights include multiple levels of review, each with stronger protections – you can (and should!) keep fighting.

Request a second internal appeal. Your first step is a second internal appeal where a different reviewer – one who wasn't involved in the original decision – examines your case. Take a look at why they denied the request, add any additional evidence to support your case, and resubmit your appeal with REQUEST FOR SECOND INTERNAL REVIEW right at the top.

Escalate to external review. If your internal appeal is denied, you have the right to an independent external review – a decision made by a reviewer completely outside your insurance company. This is one of the strongest patient protections in the system, and insurers are bound by external review decisions.

Real Examples: Formulary Changes Happening Right Now

CVS Caremark dropping Zepbound for Wegovy

CVS Health announced that starting July 2025, Caremark would prioritize Wegovy on its standard formularies and drop Zepbound – tied to a partnership with Wegovy's manufacturer, Novo Nordisk. Patients who were stable on Zepbound were suddenly told they'd need to switch, regardless of how well the medication was working for them.

If you're in this situation, the playbook is exactly what we've described above: secure an active denial (via new PA), then submit a patient appeal showing why the forced switch isn't appropriate for you – including your treatment history, failed alternatives, and the real-world consequences of switching.

BCBS FEP Dupixent Formulary Changes

In November, BCBS FEP Blue announced that Dupixent would no longer be on their formulary. Some FEP Blue plans use a closed formulary, meaning if Dupixent isn't on the list, you pay the full cost unless you win an exception. Dupixent is a popular drug used for a wide range of conditions like atopic dermatitis (eczema), nasal polyps, asthma and COPD, and many have been impacted by this coverage change – even those who were stable and responding well to treatment.

This isn't limited to FEP. BCBS Dupixent prior authorization requirements and formulary placement vary by state and plan – what's covered under BCBS Illinois Dupixent policies may differ from BCBS Alabama Dupixent coverage. If you've been denied, check your specific plan's formulary and denial reason before assuming another BCBS member's experience applies to you.

When the plan is this strict, your appeal packet needs to be especially tight: an active denial, a clear formulary exception request using the right language, a strong Letter of Medical Necessity, documented failure history, and – if you're stable on the drug – a clear argument for why forcing a switch is medically inappropriate. Especially for conditions like EoE, bullous pemphigoid, and prurigo nodularis, for which Dupixent is the only FDA-approved treatment, the argument for getting a formulary exception is clear and powerful.

How Claimable Can Help

If all of this seems like a lot, that's because it is. Insurers intentionally make the process tough to navigate, so you're more likely to just switch when facing a formulary change. But your treatment should be up to you and your doctor – not up to a rebate deal your insurer made.

We're here to help. Claimable builds customized, evidence-backed appeal letters that combine your personal health story with clinical research, policy analysis, and legal leverage – the three pillars that make appeals successful. This isn't a template or a generic form letter – every appeal is built specifically for your situation, your medication, and your insurer.

Claimable is free for many medications and situations, and otherwise costs just $39.95 + shipping. It's a fraction of the cost of a lawyer, and most cases resolve in under 10 days. We're here to help you navigate next steps. If you've hit a wall with a formulary denial, start your appeal here.

Frequently Asked Questions

Can insurance change my formulary mid-year?

Yes. While most formulary changes happen at the start of a new plan year, insurers can make changes mid-year – including removing drugs or moving them to higher tiers. These can happen at any time but are most common on 1/1 and 7/1. They're required to notify affected patients (typically 60 days in advance), but the notification process isn't always reliable. If you suspect a mid-year change, check your plan's current formulary directly on their website.

Can insurance change my formulary without notification?

They're required to notify you if you're currently on the affected medication. However, if you recently switched plans, changed your coverage level, or are newly prescribed the drug, you likely won't receive advance notice. The notification requirement only applies to patients the insurer already knows are filling that medication.

What is a formulary exception form?

Many formulary exception forms are designed for provider submissions – not patients. If you can't find a patient-specific form (which is common), you can submit a written appeal letter with the required information to your plan's appeals department. Plans are required to accept written appeals even without a standardized form. You can also use Claimable to generate and submit your request.

What is the difference between a formulary exception and a prior authorization?

A prior authorization (PA) is a coverage review required before certain medications will be approved — even if they're on the formulary. A formulary exception asks the plan to cover a drug that isn't on its approved drug list (or to override standard formulary rules). Depending on your situation, you may need to go through one or both processes — and they often happen in sequence, which is why they're easy to confuse.

How long does a formulary exception review take?

Federal rules generally require expedited review within 72 hours for urgent requests and standard review within about 15 days for pre-service appeals — often faster than the typical 30-day window for standard post-service appeals. However, timelines vary by plan type, so always confirm your plan's specific rules and explicitly request expedited review if your situation is urgent.

What if my provider says there's nothing they can do?

This is one of the most common – and most incorrect – things patients hear. Your provider may not be familiar with the formulary exception process or may assume that "not covered" means "not appealable." It doesn't. You have legal rights to challenge formulary decisions regardless of what your provider tells you. Consider sharing resources about the exception process with your provider, or explore your appeal options independently.

Do I need a lawyer to appeal a formulary exception denial?

No. While lawyers can help with complex cases, most formulary exception appeals can be handled effectively without one. What you need is the right evidence, the right language, and knowledge of your rights. Tools like Claimable are specifically designed to help patients build strong, evidence-backed appeals without the cost of legal representation.

Does Insurance Cover Zepbound for Sleep Apnea? How To Get Covered If You’re Denied
Zepbound is now approved to treat Obstructive Sleep Apnea (OSA). Read our guide to getting insurance to cover it.

If you’ve been prescribed Zepbound for obstructive sleep apnea (OSA), you’re probably asking two questions: 1. Will my insurance cover it? and 2. What do I do if coverage is denied? 

You’re not alone – many insurers are dropping or restricting coverage for GLP-1s, so insurance denying Zepbound for sleep apnea is a common problem. The good news is that denials in this case are worth appealing – and many people can get coverage back.

Zepbound (tirzepatide) is FDA-approved to treat moderate-to-severe OSA in adults with obesity, used along with a reduced-calorie diet and increased physical activity. In fact, it’s the only GLP-1 that’s approved to treat OSA. That means that even if your plan limits coverage of GLP-1s for weight loss, you can still get Zepbound covered for sleep apnea.

Quick answers: Zepbound + sleep apnea insurance

Q: Does insurance cover Zepbound for sleep apnea?

A: Some insurance plans cover Zepbound for sleep apnea, but coverage usually requires prior authorization. Your provider may need to submit documentation including your sleep study results, diagnosis, and proof that you meet obesity or BMI criteria. If insurance denies your request, don’t stop there. Many people are able to win coverage by submitting an appeal. 

Q: What do I do if insurance denies Zepbound for sleep apnea?

A: If insurance denies Zepbound for sleep apnea, start by getting the denial letter and noting the exact reason for the denial (you may see language like “not medically necessary” or “not on formulary”). Then submit an appeal that includes your sleep study results, records of your diagnosis, obesity/BMI details, and (optional but recommended) a letter of medical necessity from your doctor. If needed, request a second review of your appeal or escalate to independent review. 

If you get denied, save this quick overview of the process.

  1. Save the denial letter.
  2. Identify the reason you were denied.
  3. Gather documentation to support your case.
  4. Submit the right next move based on your denial reason. 
  5. Escalate to a second or external review if needed.

Not sure why you were denied or which next step is right for you? Use Claimable’s easy tool to guide you step-by-step through the appeals process.

Insurance denied Zepbound for sleep apnea? Here’s what to do (Step by Step)

Step 1 — Read the denial reason and appeal instructions

Before you jump into action, find these things in your denial letter or portal message. 

  • The reason you were denied. Look in your letter for language like “Why your request was denied”.
  • Appeal instructions. Your denial letter will provide information about how to appeal and where to send your request (fax or mail). 
    • Note: You might get a message in your portal before the formal denial letter comes in the mail. You don’t have to wait for the denial letter to come in order to appeal – log into your insurer’s member website and search for appeal department details. 

Step 2 — Identify why you were denied

Most denials fall into one of these buckets. Look for language like one of these in your denial letter under “why your request was denied”. 

When it comes to Zepbound for sleep apnea, all of these denial reasons can be challenged and you can get coverage back. It’s just about identifying the right steps to take.

  • Prior authorization incomplete: The PA your doctor submitted may have missing fields or missing attachments.
  • Not medically necessary: Your plan says you don’t meet their criteria to be covered for Zepbound.  
  • Not on formulary: This isn’t a medication included in your plan’s list of covered drugs. They’ll want you to try an alternative.
  • Not a covered benefit: Your plan excludes weight loss medications and isn’t recognizing sleep apnea as the primary diagnosis for Zepbound. 
  • Step therapy / alternative required: They want you to try something different before they’ll approve coverage for Zepbound.

Step 3 — Choose the right next action

  • If it’s missing info → ask your doctor to correct and resubmit the PA.
  • If it’s criteria/medical necessity → Make sure you meet the criteria, then file an appeal. Getting a letter of medical necessity from your doctor can help here. If your insurer is requiring unreasonable criteria that doesn’t match the current FDA or clinical guidelines, Claimable can help you make that case.
  • If it’s formulary → Appeal and request a formulary exception. Since Zepbound is the only GLP-1 that’s approved for sleep apnea, you should qualify for a formulary exception.
  • If it’s an exclusion → Ask your doctor to file a new PA only for OSA (not obesity). If you’re denied again, appeal. Exclusions are common for obesity, but not for sleep apnea. This happens when your request is mis-categorized, so you can clear things up in an appeal.

Zepbound for sleep apnea: Coverage overview

Does insurance cover Zepbound for sleep apnea? Sometimes, yes—but it’s usually not automatic.

“Coverage” typically depends on:

  • whether the medication is on your plan’s formulary
  • whether you meet prior authorization criteria
  • whether required documentation is submitted correctly the first time

Zepbound’s OSA indication is specifically for moderate-to-severe obstructive sleep apnea in adults with obesity (with diet and activity), so you want to make sure it’s right for you.

What insurers usually require to cover Zepbound for sleep apnea

This varies by plan, but the most common things insurance wants to see to cover Zepbound for sleep apnea are below. Call your insurer or visit your member website for a full list of coverage criteria. You can see example coverage criteria from CVS Caremark here.

Sleep study + documented OSA severity

  • Sleep study report (polysomnography or home sleep apnea test, as applicable)
  • Documented diagnosis of OSA and severity (often based on AHI/REI)

Obesity/BMI documentation + relevant clinical history

  • Current height/weight, BMI
  • Problem list / relevant comorbidities (as documented in chart notes)

Provider notes that align to plan criteria

  • Recent visit notes with diagnosis and treatment plan
  • Any documentation the plan requires (e.g., specialist involvement, prior treatment history)

Tip: A surprising number of denials happen because the right info exists—but it isn’t included in the PA submission or isn’t easy for the reviewer to find.

Common denial reasons and what to do about them

Denials are confusing. Here’s a breakdown of the most common denial reasons, what they look like in communications from your insurance, and how to fix it. Need help determining which reason you have and what strategy to use? Use Claimable's guided appeals tool to make it easy.

1) Prior auth incomplete / missing documentation

What it looks like: “Insufficient information,” “missing documentation,” “clinical records not provided.”
Fastest fix: Ask your prescriber’s office what they submitted, then resubmit with a complete packet.

2) “Not medically necessary”

What it looks like: “Does not meet criteria,” “not medically necessary.”
Fastest fix: Appeal using your plan’s stated reason. Clearly show that you meet the missing criteria – or that the criteria your insurer uses isn’t backed up by FDA or clinical guidelines (Claimable can help with this).

3) Not on formulary

What it looks like: “Not covered,” “non-formulary,” “preferred alternatives required.”
Fastest fix: Appeal, requesting a formulary exception. Include details about why alternatives aren’t suitable for you based on your condition or medications you’ve tried and failed in the past.

4) Benefit exclusion / “weight loss only”

What it looks like: “Plan excludes weight-loss medications,” “not a covered benefit”
Fastest fix: This is where the OSA indication matters. Zepbound is FDA-approved for moderate-to-severe OSA in adults with obesity – so an exclusion for weight-loss medication shouldn’t apply here. Appeal to make the case.

5) Step therapy / alternative requirement

What it looks like: “Must try X first,” “step edit.”
Fastest fix: Include information about why alternatives aren’t appropriate in your appeal. Lean on relevant state laws here – 37 states have laws that protect patients from step therapy requirements, so you may not be required to try and fail an alternative first.

How to get insurance to cover Zepbound for sleep apnea – before you have to deal with a denial

If your doctor is considering prescribing you Zepbound for sleep apnea, get ahead of any issues by determining if you’ll covered from the start.

What to ask your insurer (script)

Call the number on your insurance card and ask:

  1. Is Zepbound covered for obstructive sleep apnea under my plan?
  2. Is it on formulary? If not, what’s the exception process?
  3. What are the prior authorization criteria and where is the PA form?
  4. Where should the PA be submitted (portal/fax)?
  5. What are typical timelines, and what qualifies for an expedited review?

What to ask your provider (submission checklist)

Ask your clinician’s office to confirm the PA includes:

  • Sleep study report + OSA severity documentation
  • BMI/obesity documentation
  • A brief medical rationale tied to criteria (not generic)
  • the correct diagnosis coding and chart notes attached

Common submission mistakes to avoid

  • Missing the sleep study attachment
  • Outdated weight/BMI documentation
  • Generic notes that don’t address the plan’s stated criteria
  • Incorrect submission destination (wrong portal/fax)

How to write a Zepbound for sleep apnea appeal

Insurance is complicated, and even when you get ahead of it issues can arise. But when it comes to Zepbound for sleep apnea, most people will be able to reverse a denial when they appeal – with the right argument, documentation, and clinical backing.

What to include in your appeal

Your appeal is strongest when it mirrors the denial reason:

  1. Quote the denial reason (one sentence)
  2. Respond directly with the evidence that addresses it
  3. Attach the supporting documents and highlight the relevant lines. Include:
    1. Sleep study report
    2. OSA diagnosis
    3. Clinic notes and/or letter of medical necessity
    4. Clinical studies that support why Zepbound is right for you
    5. Any relevant laws – many states have legal protections that can help fight formulary changes, step therapy, and other inappropriate denial reasons.

If it’s a formulary appeal

  1. Make sure you’re clearly stating that this is a formulary exception request
  2. Look up what the plan is offering for alternatives, and make sure that you’re clearly laying out why those are inappropriate for you

Request a second review (internal escalation)

If your first appeal is denied:

  • Request a second-level internal appeal from your plan. Do this by sending another appeal and noting your request on the first page – making sure you address the reason for their denial. If your insurance has a separate mail/fax for second-level appeals, send it there.

External/independent review (when internal appeals fail)

By law, most plans are required to offer access to external review (independent review) after a final internal denial. Your denial paperwork should tell you how to request it. 

If your plan still won’t cover it

If you’ve exhausted the plan’s pathways, you can still explore:

  • Employer benefits escalation (HR/benefits team can sometimes clarify exceptions)
  • Manufacturer resources and savings programs (where eligible)
  • Legal action. There are several class-action lawsuits underway regarding inappropriate denial of Zepbound coverage for OSA patients, or you can speak with a lawyer about your individual options.

Read our full guide here to what to do when your appeal is denied.

Always avoid delaying OSA management—talk with your clinician about other treatment options while coverage is being sorted.

FAQs

What do I do if insurance denies Zepbound for sleep apnea?

tart by getting the denial letter and noting the exact reason for the denial (you may see language like “not medically necessary” or “not on formulary”). Then submit an appeal that includes your sleep study results, records of your diagnosis, obesity/BMI details, and (optional but recommended) a letter of medical necessity from your doctor. If needed, request a second review of your appeal or escalate to independent review. 

How do I appeal for Zepbound for sleep apnea?

Write a clear letter that outlines your case for coverage: Restate the denial reason, respond with the exact evidence that addresses it, and attach the documents (sleep study, chart notes, BMI). Ask your provider for a letter of medical necessity if helpful. Mail and fax to your insurer’s appeals department.

Why did insurance deny Zepbound for sleep apnea?

Common reasons include missing PA documentation, “not medically necessary,” the drug being non-formulary, benefit exclusions, or step therapy requirements. These can all be challenged with an appeal.

What does “not medically necessary” mean in a Zepbound sleep apnea denial?

It usually means the plan believes the documentation doesn’t prove you meet its criteria. Your appeal should focus on supplying the specific missing evidence and clarifying anything the reviewer may have missed.

What should I submit if my Zepbound sleep apnea prior authorization was denied?

Resubmit the PA, or appeal with a complete packet: denial letter, PA materials, sleep study, diagnosis/severity documentation, BMI/obesity documentation, and relevant clinician notes.

Can I appeal a plan exclusion denial for Zepbound for sleep apnea?

Often, yes – plans may still have an exception process. Most plan exclusions are when GLP-1s are for weight loss – a prescription for sleep apnea shouldn’t fall under that exclusion. However, it’s common for Zepbound to be initially denied because of exclusions, and patients may need to appeal to get coverage for OSA. Even when exclusions exist, your denial letter should explain appeal rights and next steps. 

What is a formulary exception and when should I request one?

A formulary exception is a request for coverage when a medication isn’t on your plan’s formulary (the list of covered drugs). It’s most relevant when your denial says “not covered” or “non-formulary.”

How do I request an independent review after my appeal is denied?

After a final internal denial, you may be eligible for external review through an independent organization; your plan’s final denial should include instructions on how to request external review. Claimable recommends always exhausting your appeals through the final pathway before giving up. 

What to Do When Your Insurance Plan Excludes Coverage for Your Condition
GLP-1 "plan exclusions" are becoming increasingly common. Learn what they are, and what you can do about it.

For many people living with obesity, the biggest insurance challenge isn’t a denial for a specific drug — it’s that the plan doesn’t cover any medication for that condition at all, even if the drug is FDA approved for that condition and covered for other conditions. “Plan exclusions” are becoming more common as the popularity of GLP-1 medications increases. If you’re facing one, you’re probably thinking: What do I do now?

How do I know if I have a plan exclusion for GLP-1s?

If your GLP-1 was denied, look for language like this in the denial letter. This type of language typically indicates a plan exclusion.

  • “Not a covered benefit”
  • “Your benefit plan simply does not cover this medication, no matter what the reason is that it is being requested”
  • “We denied this request based on general exclusion section of formulary”
  • “Your plan does not cover this drug when it is used for weight loss”
  • “For this drug, you may have to meet other criteria”
  • “This request has been administratively denied"
  • “Excluded from coverage”
  • “Not eligible"

You may have also received a letter in the mail ahead of your 2026 plan year notifying you of coverage changes like plan exclusions. Check your letter or plan documents for language like “medications prescribed for weight loss are excluded” or "not covered".

Plan Exclusion vs. Formulary Exclusion: What’s the Difference?

Plan exclusions and formulary exclusions are two of the most common reasons insurance denies covered. Formulary exclusions, however, are easier to fight. It’s important to understand which one you’re dealing with.

Formulary Exclusion (A Specific Drug Isn’t Covered)

A formulary is the list of drugs your insurance plan agrees to cover. Plans frequently:

  • exclude certain drugs, asking patients to use their preferred alternatives instead
  • place them in high cost-sharing tiers, or
  • cover them only for one use (e.g., diabetes) but not another (e.g., obesity). 

If the plan covers the condition (e.g., diabetes) but simply doesn’t cover your particular drug, you can ask for a formulary exception

Formulary exceptions have a legally protected process for all insurance plans, requiring them to reconsider whether a medication should be covered— even if it’s not on the formulary—because the alternatives are not equivalent and acceptable for you. Learn more about formulary exceptions and how to get one here.

Plan Exclusion (No Drugs For Your Condition Are Covered))

A plan exclusion means the plan’s policy explicitly states that it won’t cover any medicines for a specific condition category. For weight-loss medications, this often shows up as a “Weight Loss Plan Exclusion.” 

This is much harder to challenge. Unlike targeting coverage for one drug, you have to argue that the plan shouldn’t categorically avoid covering any medication for your condition. Plans are legally allowed to exclude coverage for obesity treatment because obesity is currently not recognized by Health & Human Services as a disease. Which means they can write the plan to omit all pharmacologic treatment for obesity. 

Why Obesity — But Not Other Conditions — Can Be Excluded

Under the Affordable Care Act (ACA), health plans must offer a set of Essential Health Benefits (EHBs) like hospitalization, prescription drugs, mental health care, etc. Think of these as “the basics” that you’d need to have reasonable care with an insurance plan. But obesity treatment itself is not currently listed as an EHB that plans must cover

That’s why insurers can choose a plan that says “no coverage for medications prescribed for weight loss,” and courts have generally declined to force coverage. 

By contrast, plans cannot exclude essential services for conditions like:

  • Obstructive Sleep Apnea (OSA): A sleep disorder where obesity is a primary risk factor. Treatment for OSA is typically covered even when obesity medications are not.
  • Metabolic Dysfunction–Associated Steatohepatitis (MASH): A fatty liver disease linked to obesity and commonly covered by insurance, despite the exclusion of obesity treatment.
  • Major Adverse Cardiovascular Events (MACE), including Stroke (CVA): Serious heart attack and stroke outcomes. Treatment and prevention are broadly covered even though obesity is a major underlying risk factor.

This highlights a major problem with insurance coverage: health plans will pay to treat illnesses caused by obesity once they’ve become severe enough, but they won't pay for the obesity treatment itself. Treating obesity could actually lower the risk of all those other diseases – but insurance doesn’t want to cover it until bigger issues arise.

Why Plan Exclusions Are Difficult to Appeal

When a claim is denied based on a plan exclusion, insurers usually respond:

“This service is not a covered benefit under your plan.”

That’s not a denial that the treatment is  medically  necessary for you  — it’s a statement that the plan has no obligation whatsoever to pay for it even if it is. Because of this, most appeals get rejected without any deeper review of your clinical circumstances.

So if your plan’s written documents (e.g., Summary Plan Description or Evidence of Coverage) explicitly state that “medications prescribed for weight loss are excluded,” there’s often no administrative appeal pathway under the plan itself — because, under the plan’s terms, you aren’t eligible for that benefit at all. 

What You Can Do If Your Plan Doesn’t Cover Medications For Weight Loss

Here are practical options when you’re up against a plan exclusion:

1) Appeal to Your Employer Directly

If you’re on a self-funded employer plan, you can ask them to make an exception. Self-funded employer plans are a common type of healthcare plan that is designed and funded by the employer itself Most people with healthcare through their employer have this type of plan. A self-funded plan  means your employer:

  • Can grant exceptions to plan rules;
  • Has a fiduciary duty to act in the best interests of participants;
  • May be exposed to risk if an exclusion appears arbitrary or discriminatory.

Some employers are willing to make case-specific exceptions if presented with compelling medical evidence and employee support. This usually involves writing to HR or your benefits administrator, explaining:

  • why the exclusion harms health outcomes,
  • how coverage would improve health and reduce long-term costs,
  • that the exclusion may conflict with anti-discrimination principles or ERISA fiduciary standards

How to make your appeal to HR even more effective? Organize with other colleagues impacted by the plan exclusion to show the full scale of the issue.

2) Advocate for Policy Change

If your health plan excludes obesity treatment, it’s not because the science is lacking — it’s because U.S. health policy hasn’t caught up. Changing that requires action beyond individual appeals.

Here are a few meaningful ways to get involved.

  • Support federal legislation. The Treat and Reduce Obesity Act (TROA) is an active bill in Congress that would expand Medicare coverage for FDA-approved obesity treatments and help establish obesity as a condition deserving comprehensive medical care. Medicare policy often influences private insurers, making this a critical step toward broader coverage.
  • Protect and expand coverage in public programs. Coverage for obesity medications is actively being debated in Medicare, Medicaid, TRICARE, and state employee health plans. Advocacy efforts are underway to prevent coverage rollbacks and support state-level bills that expand access to care.
  • Engage in policy advocacy and education. Public comments, patient stories, and education efforts play a real role in shaping insurance and regulatory decisions. Elevating lived experiences helps counter outdated assumptions that continue to drive exclusions.

One of the easiest ways to participate is through the Obesity Action Coalition (OAC), a leading nonprofit organization advocating for people living with obesity. OAC provides tools to:

  • Sign petitions
  • Contact elected representatives
  • Support active federal and state legislation
  • Share experiences that inform policy advocacy

👉 Learn more and take action at obesityaction.org/action-center

Policy change takes time, but it’s the only path to permanently ending blanket exclusions for obesity treatment. Individual voices matter — especially when they’re raised together.

3) Explore Cash Pay and Direct Pay Options

Even when insurance coverage is excluded, there are increasingly affordable cash-pay options for weight-loss medications:

  • Wegovy: Newly released oral Wegovy tablets are available for approximately $149–$299 per month, depending on dose. Cash-pay injectable Wegovy options are available starting around $349 per month. Visit NovoCare for current pricing and eligibility details.

  • Zepbound: Cash-pay Zepbound vials are available for approximately $299–$449 per month, depending on dose. At this time, prefilled Zepbound injection pens are not offered at a reduced cash-pay price. Visit LillyDirect for current pricing and eligibility details.

These direct-to-consumer programs are not insurance coverage, but they can provide access when a health plan excludes treatment. A valid prescription from a licensed healthcare provider is required.

FAQs


Why is my GLP-1 not covered by insurance?

There are a few common reasons: your plan may have a weight loss medication exclusion, the specific drug may not be on the formulary, or your request may require prior authorization and didn’t meet the plan’s criteria. The denial letter usually includes the exact reason—look for phrases like “not a covered benefit,” “excluded from coverage,” or “not on formulary.”

What does it mean when a GLP-1 is “not a covered benefit”?

“Not a covered benefit” usually means your plan explicitly excludes treatments for your condition. This is increasingly common for GLP-1s. In many cases, your next step is to request the plan’s written policy language as well as explore if other conditions you have been diagnosed with, like sleep apnea or fatty liver disease, are eligible for coverage for the medication.

What does “excluded from coverage” mean on a denial letter?

“Excluded from coverage” typically means your plan documents explicitly state the plan does not cover the drug (or drug category) for that use (often weight loss). It’s still worth confirming whether it’s a true plan exclusion versus a drug-specific formulary issue or an administrative error.

Is a plan exclusion the same as a formulary exclusion?

No. A formulary exclusion means the plan doesn’t cover a specific drug (or prefers alternatives). A plan exclusion means the plan doesn’t cover any drugs for a category/condition (like weight loss medications), which is typically harder to overturn.

Can I appeal a plan exclusion for Wegovy, Zepbound, or other medications?

Sometimes – but it depends on the plan and the type of decision being made. If your denial is truly based on a plan exclusion, a standard appeal may be limited; however, you may still be able to request a coverage exception, pursue an employer-level exception (for employer-sponsored plans), or escalate through available review options if the plan allows it.

Why does my plan cover Zepbound for OSA or Wegovy for MASH, but not for weight loss?

Many plans cover GLP-1s for specific diagnoses (like diabetes or OSA) but exclude or restrict coverage for weight loss/obesity. Your denial letter may say the plan “only covers this drug for certain conditions” or that it’s “not covered for your diagnosis.”

Does insurance cover Wegovy for weight loss?

Some plans do, but many require prior authorization and some plans exclude weight loss medications entirely. The fastest way to confirm is to check your plan formulary and your plan’s pharmacy benefit rules—and if you’re denied, review the denial letter for whether it’s a criteria denial or a plan exclusion.

Does insurance cover Zepbound for weight loss?

Some insurance plans cover Zepbound for weight loss with prior authorization, while others exclude weight loss medications as a benefit category. If you’re denied, the exact wording matters: “criteria not met” usually means you can appeal with documentation, while “excluded from coverage” may require an exception or employer benefits route.

Are weight loss drugs covered by insurance in general? Which insurance plans cover weight loss?

Sometimes, but it’s inconsistent. Many plans cover certain weight loss treatments or programs, while excluding weight loss medications – or covering them only under strict criteria and prior authorization rules. The most reliable way to know is to check your specific plan’s language.

Which weight loss medications are most likely to be covered?

Coverage depends on the plan’s formulary, tiering, and prior authorization rules. Some plans cover a limited set of medications or prefer certain options, while excluding others. If your plan covers weight loss medications at all, the next step is often figuring out which drugs are preferred and what documentation is required.

What should I do if my GLP-1 is denied as “not medically necessary”?

That’s usually not a plan exclusion—it typically means the plan thinks the request doesn’t meet coverage criteria or doesn’t have enough documentation. Ask for the exact criteria used, gather supporting documentation with your prescriber, and submit an internal appeal or resubmission (depending on plan instructions).

If my plan excludes weight loss medications, can my employer override it?

Sometimes—particularly for employer-sponsored plans, where benefit design decisions may be made by the employer. Employees can sometimes request the employer/benefits administrator review the exclusion or consider an exception process. (This varies by employer and plan structure.)

How do I find out if my plan is self-funded?

You can ask your HR/benefits team or the plan administrator. You can also look in your plan documents for language about who pays claims (employer vs insurer) or who the plan sponsor is. If you’re unsure, ask: “Is this plan self-funded or fully insured?”

Can I switch insurance plans to get GLP-1 coverage?

If you have an opportunity to change plans (like open enrollment or a qualifying life event), you can compare formularies and benefit exclusions before enrolling. Make sure you’re checking both (1) whether the drug is covered and (2) whether weight loss medications are excluded.

If insurance won’t cover my GLP-1, what are my options?

Options may include pursuing an exception pathway (if available), employer benefits advocacy (for employer coverage), exploring manufacturer savings programs (if eligible), or cash-pay/direct-pay programs. Which option is best depends on whether your denial is a true plan exclusion or a criteria/formulary denial.

Coverage Exception & Policy Review Request (Self-Funded Employer Plan)

[Your Name]
[Street Address]
[City, State, ZIP]
[Phone Number]
[Email Address]
[Date]

[Benefits Committee or HR Representative Name]
[Job Title]
[Company Name]
[Company Address]

Dear [Benefits or Human Resources Representative Name],

I am writing to ask for your help with health insurance coverage for medical care that my healthcare provider has determined is medically necessary. I am grateful for the benefits that [Company Name] provides and for the company’s stated commitment to employee well‑being, equity, and long‑term health. It is in that spirit that I am requesting a case‑specific exception to our current health plan’s exclusion of obesity treatment.

I live with the chronic disease of obesity and have been prescribed [name of medication or treatment] by my clinician as part of a comprehensive treatment plan. This recommendation follows sustained lifestyle interventions and reflects current medical consensus regarding evidence‑based obesity care. I recently learned that our plan, [plan name / administrator], excludes coverage for medications prescribed for obesity, regardless of medical necessity.

This exclusion has made clinically appropriate care inaccessible and financially prohibitive for me. Obesity has already had meaningful impacts on my health and quality of life, including [briefly describe related conditions, risks, or symptoms]. My provider has determined that continued treatment is critical to improving my health trajectory and reducing future medical risk.

Why I Am Requesting an Exception:
Obesity Is a Chronic Disease With Serious Health Consequences

Obesity is widely recognized by the medical community as a chronic, progressive disease associated with increased risk of cardiovascular disease, type 2 diabetes, stroke, certain cancers, sleep apnea, and other serious conditions. National data show that more than 40% of U.S. adults live with obesity, and obesity‑related medical costs exceed $170 billion annually. Treating obesity improves health outcomes and reduces long‑term healthcare costs for both individuals and employers.

Importantly, not all obesity treatments work for all patients. Clinical guidelines emphasize the need for individualized care, including FDA‑approved pharmacologic therapies when lifestyle interventions alone are insufficient. Denying access to these therapies limits clinicians’ ability to provide patient‑centered care and places employees at increased risk of preventable disease progression.

Considerations for Self‑Funded Plans

I understand that [Company Name] sponsors a self‑funded health plan. As the plan sponsor, the company retains discretionary authority over benefit design and coverage decisions and holds fiduciary responsibility under the Employee Retirement Income Security Act (ERISA) to act prudently and in the best interests of plan participants.

While insurers or third‑party administrators may apply plan exclusions as written, the employer has the authority to grant individual coverage exceptions, and review whether existing exclusions continue to align with fiduciary obligations, medical standards, and employee well‑being.

I am therefore requesting review at the employer level, rather than through the insurer’s standard appeal process, which does not evaluate medical necessity when a categorical exclusion applies.

Policy and Clinical Standards (For Consideration)

While I am not a lawyer, I believe it is important for the plan sponsor to be aware of the evolving policy and clinical standards related to obesity care, which increasingly recognize obesity as a chronic disease requiring evidence-based treatment.

1. Federal Policy Momentum Reflecting Changing Standards of Care

Obesity treatment access is an active area of federal policy consideration. The Treat and Reduce Obesity Act (TROA) has been reintroduced in Congress and would expand Medicare coverage for obesity treatment, including FDA-approved medications and access to specialized providers. While TROA has not yet been enacted, its bipartisan reintroduction reflects a growing recognition at the federal level that obesity warrants comprehensive medical treatment.

Importantly, Medicare policy often serves as a bellwether for commercial insurance coverage and employer-sponsored plan design. These developments signal that longstanding exclusions for obesity treatment may be increasingly misaligned with emerging coverage norms.

2. Inconsistent Coverage of the Same Medications Across Diagnoses

Many health plans, including ours, cover GLP-1 medications when prescribed for type 2 diabetes but exclude coverage when the same medications are prescribed for obesity. This distinction exists despite substantial clinical evidence supporting their use for both conditions and growing consensus that obesity is a chronic, progressive disease.

As clinical guidance evolves, coverage decisions based solely on diagnosis—rather than individualized medical need—are increasingly being questioned by clinicians, policymakers, and plan sponsors alike. Several recent legal and policy discussions have focused on whether such distinctions reflect medical evidence or historical coverage conventions.

3. Current Clinical Guidance Supporting Obesity Treatment

Leading medical organizations continue to update standards of care to reflect advances in obesity treatment. For example, the American Diabetes Association’s Standards of Care emphasize the importance of addressing obesity as part of preventing and managing metabolic disease, including the appropriate use of pharmacologic therapy when lifestyle interventions alone are insufficient.

These guidelines reflect broader clinical consensus that obesity treatment should be individualized, evidence-based, and integrated into chronic disease management—not categorically excluded.

4. Fiduciary Considerations for Self-Funded Plan Sponsors

For self-funded employer-sponsored health plans governed by ERISA, plan sponsors have fiduciary responsibility to administer benefits prudently and in the best interests of plan participants. This includes periodically reassessing plan design choices in light of evolving medical standards, treatment effectiveness, and participant impact.

In this context, targeted, case-specific exceptions for evidence-based obesity treatment can be a measured approach that supports employee health while allowing plan sponsors to thoughtfully evaluate whether existing exclusions remain appropriate as standards continue to evolve.

My Request

In light of the above, I respectfully request that [Company Name]:

  1. Grant a case‑specific coverage exception for my prescribed obesity treatment based on medical necessity; and
  2. Consider reviewing the plan’s obesity treatment exclusion to ensure it aligns with current medical standards, fiduciary responsibilities, and the company’s commitment to employee health and equity.

I am happy to provide supporting documentation from my healthcare provider, including clinical rationale and treatment history, if helpful. I would welcome the opportunity to discuss this request or understand the next steps for review.

Thank you for your time, consideration, and commitment to supporting the health of your employees.

Sincerely,[Your Name]

Frequently Asked Questions

You have questions, we have answers.

Don't see your question? Contact us.

One of our core principles is to help patients protect their rights and level the playing field with their insurance company. This includes rights to multiple appeals, fair reviews, decision rationale, exceptions when needed, and adequate network access, among others. For more, read our post on patients rights.

Claimable’s AI-powered platform analyzes millions of data points from clinical research, appeal precedents, policy details, and your personal medical story to generate a customized appeals in minutes. This personalized approach sets Claimable apart, combining proprietary and public data, advanced analysis and your unique circumstances to deliver fast, affordable, and successful results.

We currently support appeals for over 85 life-changing treatments. Denial reasons may vary from medical necessity to out of network, and we even cover special situation like appealing plans that won’t count your copay assistance towards your deductible (hint: those policies were banned at the federal level in 2023). That said, we are rapidly growing our list of supported conditions, treatments and reasons. You can quickly check eligibility and ask to be notified when your interest becomes available. It helps us know where to focus next 🙂

We think about appeal times in a few ways. First, many professional advocates and experienced patients spend 15, 30 or even 100 hours building an appeal–but with Claimable, this takes minutes. We automate the process of analyzing, researching, strategizing and wordsmithing appeals. Next, there is the process of figuring out where you will send it (hint: expand your reach beyond appeal departments), then printing, mailing and/or faxing your submission. We handle that, too. Finally, there is the time it takes to get a decision. We request urgent reviews when appropriate, and typically receive standard appeal decisions within a couple weeks.

Review periods are mandated by applicable laws, from 72 hours for urgent, 7 days for experimental, 30 days for upcoming and 60 days for received services. Our goal is to get a response as fast as possible, since most of our clients are experiencing long care delays or extreme pain and suffering.

Claims are denied for a variety of reasons, many of which blur definitions. We focus on helping people challenge denials by proving care is needed and meets clinical standards, in addition to addressing specific issues like experimental treatments, network adequacy, formulary or site of care preference exceptions. We don't support denials for administrative errors or missing information, as we think those are best handled by simply resubmitting the claim in partnership with your provider. That said, many of our most rewarding successes have been cases previously though 'unwinnable', with providers and patients who fought tirelessly for months without appropriate response or resolution.

A denial letter is a formal notice from your insurance company explaining why a claim was denied and how you can appeal the decision. Sometimes the notice is included within an Explanation of Benefits. It is a legal requirements; if you didn’t receive one, contact your insurance company.

A letter of medical necessity is a statement from your doctor justifying why a specific treatment is critical to your care and/or urgently needed. You can attach it to your patient appeal to strengthen your case, especially if you are requesting an urgent appeal or need to skip standard ‘step therapy’ requirements. That said, we don’t require them and are often successful without them.

A claim file contains all the documents and communications your health plan used to decide whether to approve or deny your claim. Most health plans are legally required to share this information upon request. According to a ProPublica investigation, reviewing your claim file can help expose mistakes or misconduct by your health plan, which can make your appeal stronger.

Your insurer is required by law to give you written information about how to appeal, including the name of the company that reviewed your claim and where to send your appeal. Your health insurer may work with other companies, such as Pharmacy Benefit Managers (PBMs), Third-Party Administrators (TPAs), or Specialty Pharmacies, to manage your claims. These companies might be responsible for denying your claim and handling the appeal process on behalf of your insurer.

If you don't win your first appeal– don't give up! Many people are successful on their 2nd, 3rd or even 4th try, and future appeals are reviewed by independent entities. That said, we wrote a whole guide to understanding your options, including escalating your appeal and seeking other assistance for covering costs, forgiving debt or even seeking legal or regulatory support.

While both denial rates and appeal success rates vary widely by the type of health plan, state, and insurance company, studies have shown more than 50% of people win their appeal–and we apply strategies to boost your chances of success. Claimable has an 80% appeal success rate. The biggest denial challenge is that most people never appeal–allowing unjust denials to control their healthcare options because they are unaware of their rights or lack the support needed to fight back. No one needs to fight alone–Claimable is here to help. We know first hand that many denials are based on errors, inconsistencies or auto-decisions, and have proven strategies for fighting back against this injustice.

Real stories. Real impact.

Claimable helped me with a fight against my insurance company in refilling my son’s Dupixent prescription. Claimable was easy to use, checked in with me regularly and I even received a personal phone call from Warris to see if my issue had been resolved. When you feel like you have no other options and are in need of a medication that your child desperately needs, it’s great to have Claimable in your corner. They provide excellent support and won’t stop until you get the answer you need.

Claimable is nothing short of phenomenal! My doctor and I have been trying different medications for years, trying to control my asthma, with no success. We eventually discovered that Dupixent was helping me. Just when my test results started to show improvement, my insurance company decided to not cover it! After several appeals were denied, I reached out to Claimable. I was unsure about the process and feeling very defeated... Within days my denial was overturned and I'm now receiving the medication I so desperately need. This would not have been possible without Claimable. Thank you Warris!!!

Claimable helped me to win my appeal against Caremark!!! When Caremark changed their policy to no longer cover, one of my vital medication’s, I decided to appeal the decision to see if they would reconsider covering it due to its efficacy, as well as the affordability on my part. They initially denied the claim and so I was forced to appeal. When an ad for Claimable appeared, I figured it would be best to see if Claimable would be able to assist in my appeal. Best decision ever! Not only was my appeal approved, but the coverage is for an entire year. I will definitely consider using Claimable again.

Claimable was an absolute God send for me. I'd been denied three times for a life saving procedure that insurace had dragged out for weeks. We were so discouraged with the all the denials and honestly didnt know what we were going to do, it seemed as though all hope was gone. Then we heard about Claimable!! Believe it or not, in less than 24 hours after my 1st contact with a member of thier team, my claim was overturned and I received a call from insurance telling me I had been approved!! Claimable recognized the urgency of my case and worked tirelessy gathering information needed for the appeal. If anyone reading this needs help with insurance denials, do not hesitate and contact Claimable right now!!!

Claimable’s platform and customer service are exceptional in every way. When our insurance company suddenly cut off coverage for Dupixent—a medication essential for my family member’s health—we felt overwhelmed and discouraged. Despite our doctor’s tireless efforts to appeal, the insurance company wouldn’t reconsider. That’s when we were referred to Claimable, and the difference was immediately clear.

Claimable’s system guided us step-by-step through the appeals process. The instructions were straightforward, the interface was intuitive, and whenever we had questions, their team responded quickly and thoroughly. Each phase of the appeal was clearly explained, with updates provided so we always knew what to expect.

In less than two weeks, our denial was overturned, and Dupixent coverage was restored. Thank you, Claimable. You are a life saver!

So grateful to have found Claimable through On The Pen with Dave Knapp. I had read about how Claimable has helped others with prior authorization. I admit I was skeptical, but not being able to get Zepbound approved for my sleep apnea was so frustrating. I bit the bullet went to their site and began the appeal process. The staff at Claimable... were quick to reply to questions as well as suggestions on how to succeed. I am happy to say the Zepbound was approved for one year and I am picking it up tomorrow.
Thank you again Claimable.
