Frequently Asked Questions

What is the difference between Zepbound and Mounjaro?

Zepbound and Mounjaro contain the same active ingredient (tirzepatide) but are approved for different uses. Mounjaro is for type 2 diabetes, while Zepbound is for weight management. Insurance covers them based on your diagnosis. They are separate products with different NDC numbers, so pharmacies cannot substitute one for the other.

How do I get insurance to cover Zepbound?

First, verify your plan covers anti-obesity medications. If it does, your doctor submits prior authorization documenting your BMI, weight-related conditions, and previous weight management attempts. If your plan excludes weight loss drugs, ask your employer (for group plans) about adding coverage. Consider switching plans during open enrollment.

Is Zepbound covered by Medicaid?

Medicaid coverage of weight loss drugs varies by state. Some state Medicaid programs have begun covering FDA-approved anti-obesity medications, while others explicitly exclude them. Check your state Medicaid formulary or call your Medicaid plan for specific coverage information.
