How often are Wegovy or Zepbound denials overturned on appeal?
When California members took a weight-control drug denial all the way to an independent reviewer, the reviewer overturned the plan 86.3% of the time (1,365 of 1,581 decisions, 2003 to 2026), and 87.5% when the diagnosis was endocrine or metabolic. That is a self-selected sample of appealed denials in one state, not a prediction for your claim, but it shows the plan's first answer is far from final.
What to do, in order
- Step 1
Find the reason on the letter
Plan exclusion, prior authorization, BMI criteria, step therapy or formulary status each need a different appeal. A benefit exclusion is the hardest; a criteria or step-therapy denial is a documentation exercise.
- Step 2
Get the prescriber's statement to the criteria
BMI and comorbidities, the programs and drugs already tried with dates, why the plan's preferred option is contraindicated or failed. Reviewers' findings in overturned cases mention prior therapies and published evidence most often.
- Step 3
File the internal appeal within the deadline
At least 180 days on employer and marketplace plans; a formulary exception is decided within 72 hours (24 if urgent) on marketplace plans.
- Step 4
Take it to external review
If the plan upholds, an independent reviewer decides on the record. This is the step most people skip, and the step the numbers above are about.
The deadline that applies
At least 180 days to file an internal appeal on employer and ACA plans (45 CFR 147.136; 29 CFR 2560.503-1); a formulary or step-therapy exception request is decided within 72 hours standard, 24 hours expedited (45 CFR 156.122(c); 42 CFR 423.578 for Part D). The letter controls.

Does the 86% figure apply to my insurer?
It is California IMR data across all DMHC-regulated plans. Your plan's own appeal overturn rate, if it sells on HealthCare.gov, is on its report card.
My plan says weight-loss drugs are excluded. Is that appealable?
A true benefit exclusion is appealed on the wording: whether the drug is prescribed for a covered indication (for example obstructive sleep apnea or cardiovascular risk for a drug labeled for it), whether the exclusion is stated in the plan document, and whether state law limits it. Read the exclusion sentence exactly.

Compounded products are generally not covered at all; this page is about denials of the FDA-approved drugs.
