Medicaid (weight loss)
Diabetes only
As of April 2026, Illinois 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 Illinois’s current Medicaid and plan rules before booking.

§ 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]

Bar chart of Tirzepatide dose strengths on the FDA label: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg
Tirzepatide comes in 6 strengths: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg. The chart shows what the label lists. A prescriber sets the dose.[1]

§ 06Clinical evidence
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]

Tirzepatide is the active ingredient in two Eli Lilly brands: Mounjaro and Zepbound. No generic tirzepatide is FDA-approved in the US. Mounjaro is approved for type 2 diabetes; Zepbound is approved for chronic weight management. They share an active ingredient but carry different approved indications, and insurers treat them as separate products.[1]
