Medicaid (weight loss)
Diabetes only
As of April 2026, California Medicaid covers GLP-1s for diabetes but not for weight loss. Employer and private plans can still cover them; that is a plan-design choice, not a state rule.

Medicaid status above is for weight-loss use and was compiled April 2026 from KFF and public Medicaid trackers; only 13 states cover it and several are mid-change, so confirm California’s current Medicaid and plan rules before booking.

§ 04Medication factsheet
cited · last review 2026.05.19

An injectable medication for adults with type 2 diabetes. Same molecule as Zepbound.

Mounjaro is the brand name Eli Lilly uses for tirzepatide approved for type 2 diabetes. It is a once-weekly subcutaneous injection and the first approved dual GIP/GLP-1 receptor agonist. It activates two gut-hormone pathways rather than one. The identical molecule, marketed as Zepbound, is the FDA-approved formulation for chronic weight management.[2][3]

In the SURPASS-2 head-to-head trial, tirzepatide produced greater HbA1c reductions and greater weight loss than semaglutide 1 mg across all doses. Across the SURPASS program, tirzepatide lowered HbA1c by approximately 1.8 to 2.6 percentage points. Mounjaro is approved as an adjunct to diet and exercise for glycemic control in adults with type 2 diabetes.[1]

Mounjaro and Zepbound are both tirzepatide, made by Eli Lilly, but they carry different FDA-approved indications. Mounjaro is approved for type 2 diabetes; Zepbound is approved for chronic weight management. Insurers treat them as separate products, and coverage differs sharply between the two.[1]
