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. GLPHelper provides information and provider matching, not medical or coverage advice.

§ 04Medication factsheet
cited · last review 2026.05.19

The molecule in Mounjaro and Zepbound. It acts on two gut-hormone pathways, GIP and GLP-1.

Tirzepatide is a once-weekly injection sold by Eli Lilly as Mounjaro (for type 2 diabetes) and Zepbound (for chronic weight management). It is the first approved dual GIP/GLP-1 receptor agonist. It activates two gut-hormone pathways rather than one, which is associated with greater average weight loss than single GLP-1 agonists.[2][3]

In SURMOUNT-1, adults with obesity (without diabetes) lost a mean of 20.9% of body weight on the 15 mg dose at 72 weeks, versus 3.1% on placebo. In the SURPASS-2 head-to-head diabetes trial, tirzepatide produced larger HbA1c and weight reductions than semaglutide 1 mg.[1]

STEP 1 to 4 + SELECT (N = 17,604)

What the trials actually showed.

We summarize the SURMOUNT weight-management program and the SURPASS diabetes program, including the SURPASS-2 head-to-head against semaglutide. Figures are means at each trial's primary endpoint.

SURMOUNT-1 randomized 2,539 adults with obesity (without diabetes) across 72 weeks. Mean weight change was −15.0% (5 mg), −19.5% (10 mg), and −20.9% (15 mg) versus −3.1% with placebo. A majority of patients on the higher doses lost ≥20% of body weight.[2]

§ 09Frequently asked: Tirzepatide in California

The questions people ask before they book.

Answers reviewed by the GLPHelper Medical Team. Citations link to primary sources, never marketing copy.

Yes. Tirzepatide is the active molecule in both Eli Lilly products. Mounjaro is approved for type 2 diabetes; Zepbound is approved for chronic weight management. They are the same drug with different approved indications, and insurers treat them as separate products.[1]
