Why Wegovy Gets Denied (And the Winning Response for Each)

Most denials fall into predictable buckets, and each has a matching “best” letter:

1. PA denied / incomplete documentation / criteria not met → Template #1

2. “Not medically necessary” → Template #2 (plus chart notes + objective measures)

3. Step therapy (“try cheaper meds first”) → Template #3

4. Non-formulary (“not on the drug list”) → Template #4

5. Continuation/renewal denied (reauthorization requires proof of response) → Template #5

My opinion: Most people lose Wegovy appeals because they argue fairness instead of policy. Your appeal should read like a clean case file that makes it easy for a reviewer to check boxes and say “approved.”

The Wegovy “Medical Necessity Packet” (Attach This to Any Appeal)

Think of your appeal as a packet, not just a letter. Your letter is the cover sheet; the attachments do the heavy lifting.

Include what applies

• Denial letter (and any PA reference number)

• Current height, weight, and BMI (with dated documentation)

• Weight/BMI history timeline (baseline → current)

• Diagnoses/comorbidities documentation (examples: hypertension, dyslipidemia, prediabetes, OSA, cardiovascular risk factors)

• Evidence of lifestyle intervention (nutrition counseling notes, program participation, coaching summaries, etc.)

• Prior medication history (dates, outcomes, intolerance, contraindications)

• 
  
  

  ---

  
  

  Labs and vitals as relevant (A1c, lipids, BP)

• Provider Letter of Medical Necessity (Template #2), signed and on letterhead

Real-life example: If the denial says “criteria not met,” the fastest win is often a corrected resubmission with missing items (BMI documentation, comorbidity diagnosis codes, lifestyle program proof). That is why Template #1 is built for “paperwork denials,” which are the most fixable.

Deadlines That Can Make or Break Your Appeal

• Many plans require an internal appeal within 180 days of the denial notice (check your denial letter for your exact deadline).

• If you lose internally, external review requests are often due within four months of the final denial for ACA-regulated plans.

If delay puts your health at risk, ask about expedited review during the call.

Pro Tips That Increase Approval Odds (Fast)

• Ask for the exact criteria they used to deny you and match your packet to it line-by-line.

• Request peer-to-peer review (your prescriber speaks with the insurer’s clinician reviewer).

• Use “urgent/expedited” language if delay could worsen health outcomes. Prior authorization delays are widely reported as harmful in clinical practice, which is exactly why urgent review exists.

• Keep everything measurable: BMI dates, comorbidity diagnosis dates, lab trends, and a clean attachment list.

FAQ

Should I appeal myself, or should my doctor submit it?

Do both when possible: you submit the appeal (Template #1), and your prescriber submits the medical rationale (Template #2). If you want a step-by-step framework that works for most medication denials, use: How to Write a Strong Medication Appeal Letter (Free Sample)

What if my insurer says weight-loss meds are “excluded”?

Ask for the exact exclusion language and whether exceptions exist for medical necessity or specific comorbidities. If they still deny, escalate and consider external review eligibility (timelines vary by plan).

How long do I have to appeal?

Many ACA-regulated plans require internal appeals within 180 days of the denial notice (verify your plan’s deadline in the letter).

What evidence matters most?

A signed provider LMN, dated BMI history, comorbidity documentation, and proof of lifestyle intervention. If you need your BMI quickly for criteria language, use: BMI Calculator: Quickly Check Your Body Mass Index Online

What if I’m denied for the second time?

Request the second-level appeal process, add new documentation, and tighten your “policy match” section. Start here: 7 Second-Level Appeal Letter Samples

Can I request an external review?

Often yes after internal appeals (depends on plan type). Many ACA-regulated plans require the request within four months of the final denial.

What if this is Medicare-related instead of commercial insurance?

Medicare has its own levels and timelines. Use: How to Write a Medicare Appeal Letter (Step-by-Step Guide)

Is it worth appealing at all?

Yes when the denial is documentation-based, step therapy, non-formulary, or “not medically necessary.” These are exactly the denial types designed to be reversed with complete records and clinician support.

I also got denied Zepbound. Is the strategy the same?
