Does Health Net Cover Mounjaro?
The verdict
Conditional on most plans
Health Net (Centene, California) covers Mounjaro for type 2 diabetes with prior authorization on commercial, ACA, Medicare Part D, and Medi-Cal lines. Mounjaro is not covered for weight loss. Effective 1/1/2026, Medi-Cal excludes weight-loss GLP-1s — but that policy affects Zepbound and Wegovy, not Mounjaro, which has always been diabetes-only. The weight-loss tirzepatide is Zepbound, with separate coverage.
Coverage is set by your specific plan and formulary. This is a research summary — always confirm with Health Net using your member ID.
Key facts
Effective 1/1/2026, California Medi-Cal excluded weight-loss GLP-1s. This affects Zepbound, Wegovy, and Saxenda — not Mounjaro, which is covered under Medi-Cal for type 2 diabetes only, as it has always been.

Medicare vs. commercial coverage
Whether Health Net covers Mounjaro depends heavily on which kind of plan you hold. They follow completely different rules — here's each one, side by side.
Medicare
Part D & Advantage plans
Health Net Medicare Part D plans cover Mounjaro for type 2 diabetes only — not weight loss — with prior authorization. The 2026 Part D out-of-pocket cap is $2,100; most continuous Mounjaro users for diabetes reach it within 2–3 months and pay $0 thereafter. The IRA-negotiated Medicare MFN price of $245/month begins mid-2026. Mounjaro is NOT included in the 2026 Medicare GLP-1 Bridge ($50/month, July 1 – December 31, 2027), which covers weight-loss-approved products only (Wegovy, Foundayo, Zepbound KwikPen). The Lilly savings card is not usable by Medicare beneficiaries. Verify on the Health Net Medicare formulary.
Commercial / Employer
Group & marketplace plans
Commercial/Employer: Health Net commercial plans cover Mounjaro for T2D with prior authorization. Not covered for off-label weight loss. ACA/Individual: diabetes only, PA; weight-loss GLP-1s are commonly excluded on California ACA plans. Medi-Cal (Health Net's Medicaid line in CA): diabetes only; effective 1/1/2026, Medi-Cal excludes weight-loss GLP-1s — this affects Zepbound and Wegovy but not Mounjaro, which was diabetes-only from the start. Medi-Cal cost-share for Mounjaro is nominal with PA. The Lilly savings card is not available to Medi-Cal beneficiaries. Verify tier and copay on the Health Net formulary or member services.
The 5 boxes you must tick to get approved
Commercial plans that will consider Mounjaro require prior authorization. Check off what applies to you to see how close you are — this is a guide, not a guarantee of approval.
Meet all 5 and you have a documented case for approval. Missing any one is the most common reason requests are denied.
Your cost, three ways
What Mounjaro actually costs you swings enormously depending on how it's covered. Here's the realistic range.
Paying cash
Approximately $1,300–$1,560/month retail (WAC ~$1,080). Lilly savings card: $499/month for commercially insured patients without coverage (max $647/month, up to 13 fills, expires 12/31/2026). Not available to Medicare or Medi-Cal beneficiaries.
List price with no coverage — before any manufacturer savings card.
With coverage
Commercial: plan-specific cost-share — verify on Health Net formulary. Lilly savings card: as low as $25/month for commercially insured patients with coverage. Medicare Part D: 25% coinsurance after deductible to the $2,100 OOP cap 2026; MFN $245/month mid-2026. Medi-Cal: nominal cost-share with PA.
Typical monthly copay once prior authorization is approved.
Bridge program
The 2026 Medicare GLP-1 Bridge ($50/month) covers weight-loss-approved products only (Wegovy, Foundayo, Zepbound KwikPen). Mounjaro is not included.
Reduced copay through the assistance program, where eligible.
All figures are estimates; actual cost-share varies by Health Net product, plan, and pharmacy. Confirm tier and copay on the Health Net formulary or by calling member services. The Lilly savings card applies only to commercially insured patients and expires 12/31/2026.
Check YOUR exact coverage in 3 steps
General answers only get you so far. Here's how to confirm your own plan's decision in a few minutes.
- 1
Look up Mounjaro on the Health Net formulary
Visit healthnet.com or your Health Net member portal and use the plan drug list (formulary) for your specific product (commercial, ACA, Medicare Part D, or Medi-Cal). Search for 'Mounjaro' or 'tirzepatide'. Confirm it is listed for type 2 diabetes (E11.x), note the tier, and check whether prior authorization is required. Health Net operates multiple plan types in California — coverage details vary by product.
- 2
Have your prescriber submit the prior authorization
Your prescriber must document your confirmed T2D diagnosis, A1c of 6.5% or higher, and prior oral agent step therapy (metformin plus typically one additional agent). Ask your prescriber's office to submit a PA request to Health Net. Verify the specific PA criteria on the Health Net formulary before submission.
- 3
Call Health Net member services to confirm coverage and Medi-Cal status
Call the number on the back of your Health Net card. Ask: Is Mounjaro covered for type 2 diabetes on my plan? What is my cost-share after prior authorization? Does the Medi-Cal weight-loss GLP-1 exclusion (1/1/2026) affect my Mounjaro coverage? (Answer: No — Mounjaro is covered for diabetes only and was never covered for weight loss under Medi-Cal.)
Options if Health Net won't cover Mounjaro
A denial isn't the end of the road. These are the paths people commonly explore next — discuss any of them with your prescriber.
Ozempic (semaglutide)
FDA-approved for type 2 diabetes. Often covered with PA on Health Net commercial and Medicare Part D plans; may be at a more favorable tier than Mounjaro — verify on plan formulary.
Trulicity (dulaglutide)
FDA-approved for T2D. GLP-1 alternative with lower list price; often preferred tier on California Medi-Cal and commercial formularies — verify on Health Net plan.
Jardiance (empagliflozin)
SGLT2 inhibitor for T2D with cardiovascular benefits. Often preferred tier; may be required as step therapy before GLP-1 approval. Verify on Health Net formulary.
Zepbound (tirzepatide) — weight loss only
Same molecule as Mounjaro (tirzepatide) but FDA-approved for chronic weight management and obstructive sleep apnea — not diabetes. Has separate coverage; included in the 2026 Medicare GLP-1 Bridge for weight-loss-approved products. Medi-Cal excludes weight-loss GLP-1s from 1/1/2026 — verify Zepbound status on plan. Do not substitute Mounjaro for Zepbound — they are different FDA approvals.
These options are listed for information only — your own clinician decides what is appropriate for you.
