Does Texas Medicaid Cover Mounjaro? Texas Medicaid Guide 2026
Texas residents covered by Medicaid asking about Mounjaro coverage, it depends on several factors. Texas Medicaid — managed by the Texas HHSC — applies unique criteria for Mounjaro (tirzepatide) that may surprise those coming from commercial insurance.
Texas Medicaid’s Coverage Rules for Mounjaro
By federal mandate, Medicaid programs must cover any drug from a manufacturer with a rebate agreement from manufacturers participating in the Medicaid Drug Rebate Program. Eli Lilly is enrolled in this program, which means Texas Medicaid has to include Mounjaro — though it may apply prior authorization and utilization controls.
What this means:
- Mounjaro is included in Texas Medicaid’s PDL but may be non-preferred
- Prior authorization is required for all enrollees
- Patient cost: Little to no out-of-pocket cost (federal rules cap Medicaid copays)
- Managed care organizations (MCOs) in Texas might impose their own PA criteria on top of state rules
Coverage for Different Diagnoses
For type 2 diabetes:
- Approval is the expected path for the FDA-approved indication of type 2 diabetes
- Needed documentation: diagnosis codes, lab results, and medication history
- The majority of managed care plans authorize Mounjaro when PA criteria are met
For weight loss/obesity:
- Texas Medicaid has traditionally excluded anti-obesity medications
- That said, CMS guidance has opened the door for states to add weight management drugs via waivers
- Verify with Texas Medicaid member services for the most current formulary status
