How to Get Your GLP-1 Medication Covered
Steps to maximize your chances of getting insurance to pay for weight loss medication in Illinois.
Check your formulary
Call your insurance company or check their formulary online. Ask specifically if Wegovy or Zepbound is covered for weight loss. In Illinois, 95.5% of GLP-1 clinics accept insurance, suggesting strong insurer participation.
Get your BMI documented
Most insurers require a BMI of 30+ or 27+ with at least one weight-related condition (Type 2 diabetes, high blood pressure, sleep apnea, high cholesterol). Have your doctor document this at your next visit.
Submit prior authorization
Your prescribing provider submits the prior auth. Include your BMI history, comorbidities, and evidence of previous weight loss attempts (diet, exercise programs). This typically takes 3-14 business days.
Appeal if denied
If denied, you have the right to appeal. Have your doctor write a letter of medical necessity. Include clinical trial data showing cardiovascular and metabolic benefits. Many denials are overturned on appeal.
Use savings cards as backup
While waiting for approval, both Novo Nordisk (Wegovy) and Eli Lilly (Zepbound) offer manufacturer savings cards that can reduce your copay to as low as $25/month for eligible commercially insured patients.
