Semaglutide denied for missing prior authorization by UnitedHealthcare?

Q: How long do I have to appeal a UnitedHealthcare Semaglutide denial?

Internal appeal window: Typically 180 days from the denial date. External review window: Typically 60–120 days after the final internal denial. The clock starts from the date on the denial letter.

If the original prescription wasn't run through prior auth, the path is to submit a PA now with a medical-necessity letter — many plans then back-date approval to the date of service.

US health-plan appeal rights

Cite: Most US health plans have appeal rights under either the ACA, ERISA, or Medicare/Medicaid rules

Most US health plans are required by federal law to give you both an internal appeal (where the insurer reconsiders) and an external review (where an independent reviewer decides). The exact timelines and processes depend on what kind of plan you have — marketplace / employer group, self-funded, Medicare Advantage, or Medicaid MCO — but in every case there's a window after the denial during which you have the right to fight it.

Internal appeal window

Typically 180 days from the denial date

External review window

Typically 60–120 days after the final internal denial

What UnitedHealthcare typically requires

BMI >=30, OR BMI >=27 with at least one weight-related comorbidity (T2DM, hypertension, dyslipidemia, CVD, OSA). 6-month documented diet/exercise program. Step therapy: failed/contraindicated phentermine/topiramate or Contrave trial.

Source policy: GLP-1 Receptor Agonists for Weight Management

What works in the appeal

Step-therapy: Document contraindications to required agents - phentermine contraindicated in cardiovascular disease, uncontrolled hypertension, hyperthyroidism, glaucoma, MAOI use within 14 days (FDA prescribing information); phentermine/topiramate contraindicated in pregnancy, glaucoma, hyperthyroidism, MAOI use (FDA prescribing information); naltrexone/bupropion contraindicated in uncontrolled hypertension, seizure disorders, eating disorders, chronic opioid use, abrupt discontinuation of alcohol/benzodiazepines (FDA prescribing information). If prior trial completed: document inadequate response (weight loss <5% after 12 weeks per 2016 AACE/ACE obesity guidelines) or intolerance with specific adverse effects (e.g., tachycardia, insomnia, nausea, headache). Cite semaglutide 2.4mg FDA approval for chronic weight management in adults with obesity or overweight with weight-related comorbidity (June 2021). Reference STEP 1 trial showing semaglutide produced mean 14.9% body weight reduction vs 2.4% with placebo at 68 weeks (NEJM 2021;384:989-1002). Cite AMA recognition of obesity as a disease requiring treatment (2013) and 2016 AACE/ACE obesity algorithm supporting GLP-1 receptor agonists when lifestyle and first-line pharmacotherapy fail or are contraindicated. BMI threshold: Verify FDA indication (BMI ≥30 kg/m² or ≥27 kg/m² with weight-related comorbidity such as hypertension, type 2 diabetes, or dyslipidemia). Supervised program: Document prior lifestyle intervention attempts including dietary counseling and increased physical activity per FDA indication requirements. Employer carve-out: Request plan documents confirming exclusion; appeal as medically necessary treatment for chronic disease; consider state parity laws if applicable.
