Denied for Wegovy or Zepbound? The Appeal Ladder, in Plain English

There are really only two ladders here. A commercial or ACA marketplace plan gives you an internal appeal, then external review. Medicare Part D gives you five levels with different deadlines at every rung. The table below is both ladders side by side, with the actual filing windows.

Last fact-checked: July 20, 2026

Figure out which ladder you're on before you write anything. The letter you write for a Part D redetermination is not the letter you'd write for an ACA internal appeal: the deadlines, the recipient, and even the next step up differ.

The appeal ladder: Part D vs. commercial/ACA, side by side

Find your row, then skip straight to that section below. The rungs don't line up perfectly (Part D has three more levels than a commercial appeal does), but the first two steps map closely enough to compare directly.

Same idea (denial → appeal → external review), two different rulebooks.
Rung	Medicare Part D drug plan	Commercial / ACA marketplace plan
1. First appeal — deadline to file	65 days from the plan's denial notice (this level is called redetermination)	180 days (6 months) from the denial notice (this level is the internal appeal)
1. First appeal — decision deadline	7 days (standard benefit request), 14 days (payment request), or 72 hours (expedited)	30 days (service not yet received), 60 days (service already received), or at least 4 business days if urgent
2. Second appeal — deadline to file	60 days from the Level 1 decision (this level is reconsideration by an Independent Review Entity)	4 months from the internal-appeal denial (this level is external review by an independent reviewer)
2. Second appeal — decision deadline	Same 7-day/14-day standard, or 72 hours if expedited	45 days standard, or 72 hours if expedited
Further levels	Level 3: OMHA hearing before an Administrative Law Judge (case must be worth at least $180, 2024 threshold). Level 4: Medicare Appeals Council. Level 5: federal district court (case must be worth at least $1,840, filed within 60 days of the Level 4 decision).	None. The external reviewer's decision is binding on the insurer.

Medicare first: is this actually a Bridge question?

If you have Medicare Part D and the denial is about a weight-loss GLP-1, stop before you write an appeal at all. There's a temporary program called the Medicare GLP-1 Bridge that might make the appeal unnecessary. It runs July 1, 2026 through December 31, 2027, and it's a flat $50-a-month copay for people who qualify. It doesn't replace Part D; it sits outside it. Source: CMS

The Bridge covers exactly three things: Foundayo tablets, Wegovy (injection or tablet), and the Zepbound KwikPen. It does not cover Ozempic, Zepbound's single-dose pens or vials, or compounded GLP-1s. So if your prescription is for one of those, the Bridge was never going to say yes, appeal or not. Source: Medicare.gov: weight-loss drugs

And the Bridge has its own exclusion list that has nothing to do with paperwork. If you have type 2 diabetes, moderate-to-severe sleep apnea, or fatty liver disease, you're not Bridge-eligible at all. The Bridge routes those conditions to your regular Part D plan instead, and that's not a decision an appeal can overturn: it's how the program is built. Source: Medicare.gov: weight-loss drugs

An appeal fixes a wrong decision. It doesn't rewrite the rules. If your denial is correct under the Bridge's own criteria (wrong drug form, excluded condition, BMI that doesn't clear the bar), no appeal changes that. Save the appeal for when the plan got something wrong: misapplied a rule, missed documentation your prescriber actually sent, or processed the request under the wrong program entirely.

The Part D ladder, level by level

Level 1 — Redetermination.
Ask your plan for a redetermination within 65 days of the date on its denial notice. Standard requests get a decision within 7 days for a benefit request or 14 days for a payment request; ask for an expedited review and, if it qualifies, you'll hear back within 72 hours.
Level 2 — Reconsideration by an Independent Review Entity (IRE).
If the plan upholds its denial, you have 60 days from that decision to take it to the Part D IRE, an outside reviewer rather than your plan. The IRE works on the same 7-day/14-day standard timeline, or 72 hours expedited.
Level 3 — OMHA hearing before an Administrative Law Judge.
Beyond the IRE, you can request a hearing before an Administrative Law Judge through the Office of Medicare Hearings and Appeals. Your case has to clear a minimum dollar threshold ($180 for 2024) to qualify at this level.
Level 4 — Medicare Appeals Council.
If you disagree with the ALJ's decision, or the ALJ doesn't rule in time, you can ask the Medicare Appeals Council to review it.
Level 5 — Federal district court.
The last stop, and it also has a dollar minimum ($1,840 for 2024) and a 60-day filing window from the Appeals Council's decision.

The commercial / ACA marketplace ladder, in detail

Internal appeal.
For an ACA-compliant, non-grandfathered plan, you have 180 days (6 months) from the denial to file. Your insurer then has 30 days to decide if you haven't received the service yet, or 60 days if you already have. If waiting that long could seriously harm your health, you can ask for an urgent decision instead; the insurer must respond within at least 4 business days.
External review.
If the internal appeal is denied, you have four months from that denial to request external review by an independent reviewer outside your insurer. A standard external review is decided within 45 days; an expedited one within 72 hours. Your insurer is required to accept whatever the external reviewer decides.

Sources: HealthCare.gov: Internal appeals; HealthCare.gov: External review

Don't borrow a Part D deadline for a commercial plan, or vice versa. 65 days and 180 days are not interchangeable, and neither are the two ladders' second rungs. Use the notice your insurer actually sent you to confirm which process, and which deadline, applies to your specific plan.

Writing the appeal itself

Whichever ladder you're on, the letter does the same job: it answers the plan's stated reason, point by point, instead of restating that you want the drug.

Before you write anything

Copy the exact denial reason word for word from the notice.
Confirm the drug and formulation that was actually requested: tablet vs. injection vs. KwikPen vs. vial matters for GLP-1s specifically.
Confirm which ladder applies (Part D drug plan, Medicare Advantage, or a commercial/ACA plan) from the notice itself, not from assumption.
Note the real deadline from the table above, and file with room to spare.

Lead with what you're asking for.
Name the drug and formulation, name the appeal level you're requesting, and be direct about it.
Quote the plan's reason back to them.
This keeps the appeal anchored to their actual objection instead of a generic plea.
Answer each point in the same order the notice raised it.
If the notice lists three requirements you supposedly didn't meet, answer all three, in that order, with the specific fact or document that addresses each one.
Fix routing errors explicitly, if that's the issue.
If the real problem is that your request should have gone through normal Part D instead of the Bridge (or the reverse), say so plainly and cite the rule.
Ask for a written decision, and keep a copy of everything.
Follow the specific filing method in the denial notice: mail, fax, portal, or phone, followed by written confirmation.

What the appeal-success numbers actually show

It's tempting to want one clean "your appeal has an X% chance" statistic. There isn't one for GLP-1 appeals specifically, and the closest verified data point covers a different, broader category: all Medicare Advantage prior-authorization requests, not GLP-1 drugs and not Part D.

In 2024, Medicare Advantage insurers overturned 80.7% of the prior-authorization denials that were actually appealed. The catch is the word "actually": only 11.5% of denied requests were appealed at all that year. Read those two numbers together: most people who could have appealed didn't, and most of the people who did, won. Source: KFF: Medicare Advantage prior authorization determinations, 2024

That's a Medicare Advantage figure covering every kind of prior authorization, not a GLP-1-specific or Part D-drug-specific number, so treat it as a reason to actually file rather than a promise about your particular case.

Frequently asked questions

What's the very first thing I should do after a Wegovy or Zepbound denial?

Read the written denial notice and identify which ladder applies (Medicare Part D, Medicare Advantage, or a commercial/ACA marketplace plan) because the deadlines and steps differ for each. If you have Medicare, also check whether the Medicare GLP-1 Bridge might apply before you appeal anything.

How long do I have to file a Part D redetermination?

65 days from the date on your plan's denial notice.

How long do I have to file an internal appeal on a commercial or ACA marketplace plan?

180 days (6 months) from the date you receive the denial notice, for an ACA-compliant, non-grandfathered plan.

What comes after a Part D redetermination denial?

Reconsideration by a Part D Independent Review Entity (IRE), which you must request within 60 days of the redetermination decision. Beyond that are an OMHA hearing, Medicare Appeals Council review, and federal district court, each with its own dollar threshold and deadline.

What comes after an internal appeal denial on a commercial or ACA plan?

External review by an independent reviewer, which you must request within four months of the internal-appeal denial. A standard external review is decided within 45 days, or 72 hours if expedited, and the insurer must accept the outcome.

Does the Medicare GLP-1 Bridge cover Ozempic?

No. The Bridge covers only Foundayo tablet, Wegovy injection or tablet, and the Zepbound KwikPen. Ozempic, Zepbound single-dose pens and vials, and compounded GLP-1 products are excluded.

Can I appeal my way into Bridge eligibility if I have type 2 diabetes?

No. The Bridge excludes type 2 diabetes, moderate-to-severe sleep apnea, and fatty liver disease by design, and directs those conditions to normal Part D coverage instead. An appeal corrects an incorrect decision; it can't rewrite that exclusion.

How often do GLP-1 appeals actually succeed?

There's no verified GLP-1-specific success rate. The closest data point is broader: in 2024, 80.7% of appealed Medicare Advantage prior-authorization denials (all service types) were overturned, but only 11.5% of denied requests were appealed in the first place.

Can someone help me file a Medicare appeal for free?

Yes. The State Health Insurance Assistance Program offers free, one-to-one help with Medicare appeals. Find your local program at SHIPhelp.org.
