Your medication is worth $12,000 a year. Your insurer denied it. Here's how to fight back — and win.
The math is stark: most people who get denied simply give up. But nearly half of those who appeal with proper documentation win. The insurance company is counting on you not knowing this — or not knowing how to build a proper appeal.
This guide gives you the exact steps, the exact language, and the exact documentation you need.
Understanding why you were denied is the first step to winning the appeal. The most common denial reasons:
| Denial Reason | What It Actually Means | How to Counter It |
|---|---|---|
| "Not medically necessary" | Your documentation didn't match their clinical criteria | Submit HbA1c, BMI, comorbidities, and failed prior interventions |
| "Step therapy required" | They want you to try cheaper drugs first | Document any prior drug trials or contraindications |
| "Not covered benefit" | Your plan explicitly excludes weight loss drugs | Appeal using the metabolic/diabetes angle if applicable; consider external review |
| "Diagnosis code mismatch" | The prescription used obesity (E66) but you need diabetes (E11) | Ask physician to recode if diabetes or pre-diabetes is present |
| "Prior authorization incomplete" | Missing documentation from the physician | Resubmit with complete documentation checklist |
Call your insurer and request the complete denial letter in writing. Ask them specifically: "What are the exact clinical criteria required for approval?" and "What specific criteria did I fail to meet?" Write down the names of everyone you speak with. This documentation becomes part of your appeal.
Also ask: "What is my appeal deadline?" Most insurers require appeals within 30-60 days of the denial date. Missing this deadline forfeits your right to internal appeal.
Your appeal needs hard numbers. Collect everything:
Curabook PHI automatically extracts and formats all of this from your uploaded lab reports — ready for appeal submission.
This is the single most important document in your appeal. The letter should include:
Your appeal package should include:
Submit via certified mail with return receipt, or through the insurer's online portal if available. Keep copies of everything.
Follow up every 5-7 days after submission. Ask for the status and expected decision date. If the internal appeal is denied, you have the right to an independent external review — a third party reviews your case. External reviews overturn internal denials approximately 30-40% of the time for GLP-1 medications.
If all else fails, file a complaint with your state insurance commissioner. Insurers take state regulatory complaints seriously.
| Instead of this | Write this |
|---|---|
| "I need this medication to lose weight" | "This medication is medically necessary for the management of obesity (BMI [X]) with associated comorbidities including [diabetes/hypertension/PCOS]" |
| "I've tried everything and nothing works" | "Patient has attempted supervised dietary intervention and physical activity program without achieving or maintaining clinically significant weight loss, consistent with criteria under [insurer's coverage policy section X]" |
| "This medication really helped me" | "Prior treatment with [medication] demonstrated clinically significant reduction in HbA1c from [X]% to [Y]%, representing meaningful glycemic improvement" |
| "It's too expensive without insurance" | Don't mention cost — insurers don't consider patient finances in medical necessity determinations |

Build My Appeal Letter — $79 →Medicare: The GLP-1 Bridge Program (July 2026 - December 2027) provides $50/month access to approved GLP-1 medications for eligible Medicare beneficiaries with obesity. If denied under Medicare Advantage, the appeal process goes through your plan's grievance and appeals department. Medicare appeals have strict timelines (60 days for standard appeals, 72 hours for expedited).
Medicaid: California Medi-Cal removed GLP-1s for weight management in January 2026. Other state Medicaid programs vary significantly. If denied by Medicaid, you have the right to a fair hearing — an administrative law judge reviews your case. Medicaid fair hearing wins are common when the clinical case is well-documented.
