Medicaid provides health coverage to low-income individuals and families, with prescription drug benefits managed at the state level. Federal law requires state Medicaid programs to cover nearly all FDA-approved drugs from participating manufacturers, making Medicaid one of the most comprehensive drug coverage programs. Each state operates its own preferred drug list and prior authorization system.

Frequently Asked Questions

Does Medicaid cover all prescription drugs?

Medicaid must cover nearly all FDA-approved drugs from manufacturers participating in the Medicaid Drug Rebate Program. States can use preferred drug lists and require prior authorization, but they cannot outright deny medically necessary medications. Some states exclude specific categories like fertility drugs or cosmetic treatments.

How much do prescriptions cost on Medicaid?

Medicaid copays are very low, commonly a few dollars for preferred generics and somewhat more for non-preferred brands. Exact amounts are set by each state within federal nominal cost-sharing maximums, so check your state Medicaid agency. Many populations (children, pregnant women, nursing home residents) are exempt from all copays. Pharmacies cannot deny medication to Medicaid patients who cannot afford the copay.

Does Medicaid cover Ozempic and other GLP-1 drugs?

Medicaid must cover Ozempic for its FDA-approved indication (type 2 diabetes). Coverage for weight loss indications varies by state. Some states have added coverage for anti-obesity medications, while others limit coverage to diabetes treatment only. Check your state Medicaid formulary for specifics.
