How to Appeal a Weight-Loss Medication (GLP-1) Denial from Cigna

Denied for Zepbound, Wegovy, Ozempic, or Mounjaro? Step-therapy and "not medically necessary" denials are among the most overturnable — if you make the right argument.

Your deadline: most plans allow 180 days from the date on your denial letter to file an internal appeal — more time than most people think. Check the date on your letter.

Why weight-loss medication (GLP-1) claims get denied

Step therapy — the plan wants you to try a preferred drug (often Wegovy) first
Formulary exclusion — some plans exclude weight-loss drugs entirely (this one matters most, see below)
BMI or comorbidity criteria not documented in the request
Framed as "lifestyle" or "cosmetic" rather than medical

Before appealing, check your plan’s prescription drug list. If weight-loss medications are excluded (not covered under any circumstances) rather than denied, a medical-necessity appeal cannot win — that is a benefit-design issue, not a coverage decision. Our free check tells you which one you’re facing before you spend anything.

The argument that wins

Request a step-therapy exception. Almost every plan must offer one. If your doctor chose this drug for a documented clinical reason — sleep apnea, prediabetes, an intolerance to the preferred drug — the trial requirement can be waived.
Use the FDA-indication argument: tirzepatide (Zepbound) is the only GLP-1 FDA-approved to treat moderate-to-severe obstructive sleep apnea in adults with obesity. If you have OSA, requiring a drug that is not indicated for it defeats the clinical purpose.
Cite your comorbidities with documentation — prediabetes (rising A1c), hypertension, sleep apnea — to establish medical necessity beyond weight alone.

Evidence to gather

Your BMI and weight history
Comorbidity documentation: A1c results, sleep study (AHI), blood pressure readings
Records of any prior weight-loss drugs tried and why they failed or were stopped
A letter of medical necessity from your prescribing physician

Frequently asked questions

Can I appeal if my plan excludes weight-loss drugs entirely?

Usually not on medical-necessity grounds — a blanket exclusion is a benefit-design choice, not a coverage denial. Check your plan’s drug list first. Our free case check confirms this before you pay anything.

What if I haven’t tried the preferred drug?

You can request a step-therapy exception instead of completing the trial, if there is a clinical reason the preferred drug is inappropriate for you (a contraindication, a documented intolerance, or an FDA-indication mismatch).
