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 chronic weight management in adults. Same molecule as Ozempic, higher dose.

Wegovy is the brand name for semaglutide at the higher 2.4 mg dose. It is the same molecule as Ozempic, marketed by the same manufacturer for a different FDA-approved indication. It is a once-weekly subcutaneous injection in the GLP-1 receptor agonist class.[2][3]

In the STEP-1 randomized trial, 68 weeks of weekly 2.4 mg semaglutide produced a mean body-weight reduction of 14.9%, roughly 2.5× the weight loss seen at the Ozempic 1 mg dose. Wegovy is FDA-approved for chronic weight management in adults with a BMI ≥ 30, or ≥ 27 with at least one weight-related comorbidity such as hypertension or dyslipidemia.[1]

§ 06Clinical evidence
STEP 1 to 4 + SELECT (N = 17,604)

What the trials actually showed.

We summarize results from the STEP program, the global Phase IIIa trials Novo Nordisk submitted to the FDA for the weight-management indication, and the SELECT cardiovascular outcomes trial. Numbers below are means at the 68-week endpoint, 2.4 mg weekly dose.

STEP-1 randomized 1,961 adults with obesity to weekly 2.4 mg semaglutide vs placebo over 68 weeks. Mean body-weight reduction was 14.9% on semaglutide vs 2.4% on placebo. 86.4% of patients on semaglutide achieved ≥ 5% weight loss vs 31.5% on placebo.[4]
