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.

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.
