Aetna's Wegovy coverage in 2026
Aetna covers Wegovy on most commercial plans with prior authorization. However, coverage varies dramatically based on your specific employer's selected benefits — Aetna sells plans to employers and each employer chooses whether to include obesity drug coverage. Some employer plans through Aetna explicitly exclude obesity medications; others include with Wegovy on Tier 3 formulary requiring PA.
Aetna Medicare Advantage: generally cannot cover Wegovy for weight loss only (CMS exclusion of weight-loss drugs in Medicare Part D). T2D coverage through Ozempic is available.
Aetna Medicaid (Aetna Better Health): coverage by state, often more restrictive than commercial.
Federal Employee Program (FEP) through Aetna: covers Wegovy with PA when applicable.
Typical Aetna Wegovy PA requirements
BMI ≥30, OR BMI ≥27 with at least one weight-related comorbidity (hypertension, dyslipidemia, type 2 diabetes, obstructive sleep apnea, cardiovascular disease).
Documentation of structured weight-loss attempts. Aetna typically requires 6 months of documented structured weight management — supervised lifestyle program, registered dietitian visits, or structured commercial program (WW, Noom, Optavia). This is the 'step therapy' requirement.
Prescriber attestation. Your physician must attest medical necessity and intent to monitor.
Continuation criteria. Re-authorization annually requires documentation of at least 5% weight loss maintained AND continued medical necessity.
How to check your specific Aetna Wegovy coverage
Log into your Aetna member portal at aetna.com. Use 'Find a Medication' tool. Search 'Wegovy' or 'semaglutide.' Confirm formulary tier and PA requirement for your specific plan.
Call Aetna member services using number on your insurance card. Ask: (a) Is Wegovy on the formulary? (b) Is prior authorization required? (c) What are the specific PA criteria? (d) What are the copay tiers?
Ask your prescriber's office to run a real-time benefits inquiry. Most prescribing offices have access to verification tools showing your specific Aetna coverage and PA pathway.
When Aetna denies the PA
Common denial reasons: 'Not medically necessary' (BMI documentation issue), 'Step therapy not completed' (lifestyle attempt documentation), 'Plan excludes obesity medications,' 'Failed step-therapy with alternative treatments.'
Appeal strategy: get denial reason in writing. Address specific reason in appeal. Include BMI history, comorbidity documentation, prior weight management attempts. Use our appeal letter generator for personalized draft.
Peer-to-peer review: your prescriber can request a peer-to-peer call with Aetna's medical reviewer. This often reverses denials if the initial reviewer wasn't a specialist.
External review: if Aetna denies internal appeal, you have right to external review by independent medical reviewer. About 40% of external reviews reverse denials.
About 40-60% of properly appealed Aetna Wegovy denials succeed.
Aetna-specific tips
Aetna's policy bulletins document PA criteria publicly. Search 'Aetna policy semaglutide' or 'Aetna clinical policy bulletin obesity drugs' to find current criteria. Match your documentation to the explicit criteria.
Aetna often requires CDS (Clinical Decision Support) integration — your prescriber's EHR may auto-populate Aetna's PA fields if integrated. Ask about this if PA process is slow.
Aetna covers Wegovy during documented prior weight loss attempts with specific drugs (phentermine, naltrexone-bupropion, orlistat). Documenting prior trials with these older drugs strengthens your PA case.
Aetna's step-therapy override requires documented harm or ineffectiveness from required alternatives. If you tried phentermine and had cardiovascular contraindication, document that — it qualifies for step-therapy override.
If Aetna denies completely
NovoCare self-pay $499/mo for Wegovy. Manufacturer direct-pay program, not affected by insurance denial.
LillyDirect orforglipron $149/mo. Cheaper than NovoCare. Different molecule but similar efficacy. Doesn't require Aetna PA.
LillyDirect Zepbound vials $349-549/mo. Better efficacy than Wegovy semaglutide.
Multi-level appeals. Aetna has 2 internal appeal levels plus external review. Persistence often works.
Switch employer benefits at open enrollment. If your employer's Aetna plan excludes Wegovy and you have alternative plan options, evaluate during open enrollment.
