Coverage for weight loss treatment and GLP-1 medications through Aetna in Illinois typically falls under medical or pharmacy benefits rather than mental health benefits. Weight loss treatment is not subject to the Mental Health Parity and Addiction Equity Act (MHPAEA), so coverage structures differ from mental health benefits and vary significantly between plan designs and employer elections.
Aetna offers several plan types in Illinois that may include weight loss or obesity management benefits:
GLP-1 Medication Coverage: FDA-approved GLP-1 medications for weight management — such as semaglutide (Wegovy) and tirzepatide (Zepbound) — may be covered under Aetna’s pharmacy benefit when prescribed for obesity. Coverage often depends on prior authorization, qualifying BMI thresholds, and whether the plan has opted into obesity medication benefits. Diabetes-indicated GLP-1 medications may have different coverage criteria.
Prior Authorization: Prior authorization is typically required for GLP-1 weight loss medications under Aetna plans in Illinois. Plans may require documentation of qualifying BMI, failed prior weight loss attempts, and absence of contraindications. Verify prior authorization requirements with Aetna before prescribing or filling a GLP-1 prescription.
Deductibles and Copays: Cost-sharing for weight loss treatment and GLP-1 medications varies significantly by plan tier and pharmacy benefit design. Review your Summary of Benefits and Coverage for specific cost-sharing obligations.
