GLP-1 Denied by Insurance? How to Organize Your Appeal

A GLP-1 denial letter is a to-do list in disguise. Find the reason code, the deadline and the right appeal track, then build a packet that answers that exact reason. Cover-letter template included.

To appeal a GLP-1 denial, start with the letter: find the exact reason and the deadline, then send an appeal that answers that reason with the right records. Most job-based and Marketplace plans give you 180 days to file an internal appeal. Medicare Part D gives 65 days. The Medicare GLP-1 Bridge has no appeals process at all, only a corrected resubmission by your prescriber. Here's how to sort it out without drowning in paper.

If you're still waiting on a first decision, our prior authorization checklist is the better starting point. This guide is about organizing an appeal, not legal advice. Your notice and plan documents always win over anything written here.

Step 1: What does the GLP-1 denial reason actually mean?

Denial letters tend to fall into a handful of buckets. Each needs a different response:

What the letter says (roughly) What it usually means Best next move
"Not a covered benefit" / "plan exclusion" The plan doesn't pay for this drug for this use at all (check the formulary and exclusions) Ask whether any exception exists; if not, appeals rarely change exclusions. Plan for alternatives and open enrollment
"Criteria not met" The plan's prior authorization checklist wasn't satisfied Find which criterion; your prescriber supplies records showing it's met (if it is)
"Insufficient information" Something was missing or unreadable Often fastest to fix: ask which item, then resubmit or appeal with it
"Step therapy required" / "use preferred product" The plan wants a different drug tried first Prescriber explains why the preferred drug isn't appropriate, or discusses trying it
"Not medically necessary" A reviewer judged the criteria unmet on medical grounds Prescriber's letter plus records; this kind of denial can usually go to external review
"Quantity/dose limit" The amount or strength exceeds the plan's limit Prescriber explains the dose against the label and plan rules

If any term is unclear, call the plan and ask: "Which policy section was applied, and which criterion wasn't met?" Write down the answer.

Step 2: Which appeal track are you on, and what's the deadline?

Your coverage First step Deadline to file How fast they decide
Job-based or Marketplace plan Internal appeal to the plan 180 days from the denial notice 30 days if you haven't received the drug yet; 72 hours (up to 4 business days) if urgent
…then if still denied External review by an independent reviewer 4 months after the final denial Up to 45 days standard; 72 hours expedited
Medicare Part D (including Medicare Advantage drug coverage) Redetermination by the plan 65 days from the notice 7 days standard; 72 hours expedited
…then if still denied Independent Review Entity, then further levels 60 days (per Medicare.gov) Varies by level
Medicare GLP-1 Bridge No appeals process — Prescriber may resubmit with corrected or new information; decision within 72 hours
Medicaid State fair hearing process On your notice Varies by state

A few details that matter:

  • External review is mainly for denials involving medical judgment, such as medical necessity or treatment appropriateness. A straightforward "this drug is excluded" decision may not qualify. Your final denial letter has to explain whether and how to request it.
  • Your insurer must accept an external reviewer's decision, according to HealthCare.gov. Under the HHS-run process it's free; state or contracted processes can charge up to $25.
  • Medicare Bridge vs Part D: if a Bridge request was turned down because of a condition like type 2 diabetes, that request belongs with your Part D plan instead. See Bridge or regular Part D?

Put the deadline in your calendar today, with a reminder a week before.

Step 3: Build the appeal packet

Think of the packet as a folder with five pockets:

  1. The denial notice (or Explanation of Benefits) and any policy language they cited
  2. Your appeal request: the plan's form, or a letter (template below)
  3. Your prescriber's letter explaining how you meet the criteria, or why the exception is appropriate
  4. Supporting records that answer the stated reason, such as dated BMI, the relevant diagnoses or proof of a lifestyle program, and nothing more
  5. Your call log and submission proof: fax confirmations, portal screenshots, certified-mail receipts

HealthCare.gov's own list includes your name, claim number and insurance ID, any doctor letter, copies of everything, and notes from calls (date, time, name and title of the person). If someone files for you, the plan may need a signed authorization form.

Accuracy beats volume. Don't pad the story or guess at dates. If a criterion truly isn't met, say so to your prescriber and talk about other options instead.

Cover-letter template (fill in the brackets)

Re: Request for internal appeal Member name: [ ] Member ID: [ ] Claim or reference #: [ ] Drug requested: [name, form, strength] Date of denial notice: [ ]

I'm requesting an internal appeal of the decision dated [date] denying coverage of [drug] for [indication].

The notice states the reason as: "[copy exact wording]."

I believe this request meets the plan's criteria because: [one or two plain sentences, e.g. "my BMI at the start of treatment was [ ] on [date], and I have [qualifying condition], documented in the enclosed records"].

Enclosed: (1) denial notice; (2) letter from [prescriber name]; (3) [records]; (4) [other].

Please contact me at [phone] and send your decision to [address/portal]. If this is urgent, I request an expedited review because [reason, as stated by my prescriber].

[Signature, date]

Your prescriber's letter does the clinical arguing. Your letter just points at the facts.

Step 4: Ask about a peer-to-peer review

Many plans let your prescriber talk directly with the plan's reviewing clinician. It can resolve "criteria not met" faster than paper. Ask the prescriber's office whether they've requested one and whether there's a time limit.

Step 5: Track it until there's a decision

Free help exists: your state's Consumer Assistance Program can help with job-based and Marketplace appeals (HealthCare.gov notes it can even file for you), and SHIP counselors help with Medicare.

While you wait

Don't stretch or ration doses on your own. Tell your prescriber about any likely gap in supply so they can plan with you. Cost and access are among the main reasons people stop, and we cover that in why people stop GLP-1 medicines. If you're tracking side effects or weight in GLPily, keep logging. A steady record is useful whatever the decision.

Common questions

How long do I have to appeal a GLP-1 denial?

For most job-based and Marketplace plans, 180 days from the denial notice for an internal appeal, then 4 months after the final denial for external review. Medicare Part D redeterminations are due within 65 days. Always check your notice.

Can I appeal a Medicare GLP-1 Bridge denial?

CMS says the Bridge has no appeals process. Your prescriber can resubmit the prior authorization with corrected or additional information.

Will an appeal work if my plan excludes weight-loss drugs?

Exclusions are hard to overturn because the plan simply doesn't offer the benefit. Ask whether an exception process exists, and compare plans at your next open enrollment.

Can my doctor appeal for me?

Yes. A provider or another person can file on your behalf, though the plan may require a signed form from you.
