A GLP-1 denial is the start of a process, not the end of one
If your plan denied Wegovy, Zepbound, Ozempic, or Mounjaro, or approved it and then dropped it, you have a federally protected right to appeal. Under the ACA and ERISA, commercial plans generally must give you at least 180 days to file an internal appeal, and an independent external review if that internal appeal is denied. Yet fewer than 1% of denials are ever appealed, and a large share of the ones that are get overturned (broad U.S. figures from KFF and CMS, not a prediction about your case).
The reason almost no one appeals is not that they would lose. It is that a strong appeal is hours of unfamiliar work: finding your plan's actual coverage policy, mapping your documented facts to its criteria, citing the right rules correctly, and hitting every deadline. AppealIt does that work and hands you a finished, ready-to-sign appeal. You review it and submit it yourself, because you're the one appealing, and that's your legal right.
Why it happened
Why insurers deny Wegovy, Zepbound, Ozempic, and Mounjaro
Most GLP-1 denials fall into a handful of buckets. Almost all of them are administrative, and each one has a specific appeal angle.
"Not medically necessary"
The plan says your documentation doesn't establish you meet its criteria, often a qualifying BMI, a comorbidity like type 2 diabetes or hypertension, or a documented lifestyle-change trial. Appealable by mapping your records to the plan's own published criteria.
Among the more winnablePrior authorization required or lapsed
The drug needs pre-approval the plan never received, or a prior auth expired at renewal. Frequently a paperwork gap, not a coverage decision.
Often administrativeStep therapy ("try this first")
The plan wants you to fail a cheaper or preferred option before it covers this one. Appealable when you've already tried alternatives, can't take them, or the requirement doesn't fit your history.
Appealable with recordsNot a covered benefit / off formulary
The plan excludes the drug or anti-obesity medication generally, or it sits in a non-covered tier. Sometimes beatable via a formulary exception or a documented medical-necessity pathway.
Check for an exception pathQuantity limits
The plan covers the drug but limits the dose or supply. Appealable when your prescriber documents the medically appropriate dose.
DocumentableCoverage approved, then dropped
It was working, then the plan pulled it, often at plan renewal or a formulary change. There are specific protections and arguments for continuity of care.

How to appeal a GLP-1 denial, step by step
This is the same process AppealIt runs to draft your appeal. If you'd rather do it all yourself, here it is in full, honestly.
Read the letter and find the real reason
Your denial letter states a reason and a deadline, and usually a coverage-policy or rule number. That reason determines the entire appeal. Note the denial date, the appeal deadline, and any policy number cited.
Pull your plan's own coverage policy
Your insurer publishes the exact criteria it uses to cover GLP-1 medications. Get that document (your plan portal, the Summary of Benefits, or by request). This is the single most important step, because winning appeals map your facts to the plan's own rules, not to medicine in the abstract.
Gather your documentation
BMI and weight history, diagnoses and comorbidities, prior medications tried, and your prescriber's notes. The goal is to show, on paper, that you meet each criterion the plan listed.
Write the appeal, grounded in the rules
State that you meet the plan's published criteria, point to each one by name, and attach the documentation that proves it. Cite your appeal rights (ACA / ERISA). Every authority you cite should be real and verifiable, a wrong or invented citation can sink an otherwise winning appeal.
File before the deadline, then track it
Submit through the channel your plan requires, keep proof of filing, and calendar every deadline. If the internal appeal is denied, you generally have about four months to request an independent external review, which a different reviewer decides.
Why AppealIt
We draft all of that, and we verify every citation
Anyone, or any chatbot, can generate an appeal letter. The risk is that it cites a rule, trial, or policy that doesn't actually say what the letter claims, or doesn't exist. A made-up citation doesn't just look bad; it can sink the appeal. That's the part we built our engine around.
- Every citation verified. We ground your appeal only in authorities we confirm are real and that actually apply to your plan and your drug. No invented policies, no mismatched trials.
- Grounded in your plan's own coverage rules, the move that wins, mapped to your documented facts.
- Free for you. No fee, no contingency, no charge of any kind. We never take money from your insurer either.
- You stay in control. We draft the appeal and hand it to you finished. You review, sign, and submit it yourself, because you're the one appealing, and that's your legal right.
- We track the clock for you, reminding you before your deadline and helping with the annual renewal so coverage doesn't lapse again.
- An honest answer, free. We'll tell you plainly if your denial isn't worth appealing, before you spend a minute on it.
Straight answers
GLP-1 appeal questions, answered
How long do I have to appeal a GLP-1 denial?
Most plans give you 60 to 180 days from the denial date to file an internal appeal, and many commercial plans use the 180-day federal floor under the ACA and ERISA. The exact window is on your letter and in your plan documents. If the internal appeal is denied, you generally have about four months to request an independent external review. The clock starts at the denial date, so the sooner you look, the better.
Can I appeal a "not medically necessary" GLP-1 denial?
Yes, and it's one of the more appealable GLP-1 denials. Plans publish the exact medical-necessity criteria they use, for example a qualifying BMI, a comorbidity, or a documented lifestyle trial. A strong appeal maps your documented facts to the plan's own published criteria rather than arguing medicine in the abstract.
What is AppealIt's GLP-1 appeal success rate?
We don't publish a win rate, because outcomes vary by denial type, plan, and the facts of each case, and we won't invent a number. Broad U.S. data shows a large share of appealed denials are overturned, while fewer than 1% are ever appealed. We'll tell you honestly what we think your specific denial looks like, for free.
Does it cost anything to appeal with AppealIt?
No. It's free for you, and the patient pays $0. There's no fee, no contingency, and nothing to pay if it works. So what's the catch? There isn't one: we're building partnerships that fund the service, so patients are never charged and we never take money from your insurer.
Are you lawyers? Is this legal or medical advice?
No. AppealIt is a patient-advocacy tool that helps you prepare your own administrative appeal, the same right any patient has. We draft it; you review, sign, and submit it, so you stay in control. We're not a law firm and we don't give legal advice. We also don't give medical advice; what care you need stays between you and your prescriber.
Your GLP-1 was denied. Let's not let the no stand.
It takes a couple of minutes to find out if your denial can still be appealed, and it costs nothing to ask.
