Does Tufts Health Plan Cover Mounjaro?
The verdict
Conditional on most plans
Tufts Health Plan (part of Point32Health, along with Harvard Pilgrim) covers Mounjaro for type 2 diabetes with prior authorization across commercial, ACA, and Medicare Part D lines. Mounjaro is not covered for weight loss under any Tufts line. Massachusetts Medicaid covers Mounjaro for diabetes; Wegovy and Zepbound are restricted. The weight-loss tirzepatide product is Zepbound, with separate and often-restricted coverage. Verify tier and criteria on the Tufts formulary.
Coverage is set by your specific plan and formulary. This is a research summary — always confirm with Tufts Health Plan using your member ID.

Medicare vs. commercial coverage
Whether Tufts Health Plan 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
Medicare Part D covers Mounjaro for type 2 diabetes only — not weight loss — at a specialty or non-preferred tier with prior authorization. The 2026 out-of-pocket cap is $2,100; most continuous users reach it within 2–3 months and pay $0 for the rest of the year. 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, 2026 – Dec 31, 2027), which covers weight-loss-approved products only. Lilly savings card is not usable by Medicare beneficiaries. Verify your specific Tufts Medicare plan formulary each year.
Commercial / Employer
Group & marketplace plans
Commercial and employer-sponsored Tufts Health Plan plans cover Mounjaro for type 2 diabetes with prior authorization; off-label weight-loss use (diagnosis code E66.x) is denied. ACA/Individual plans cover Mounjaro for T2D with PA; weight-loss GLP-1s are commonly excluded. Massachusetts Medicaid covers Mounjaro for diabetes with PA at nominal cost-share; Wegovy and Zepbound are restricted under MassHealth. Commercially insured patients with coverage may pay as little as $25/month via the Lilly savings card (excludes government programs; expires 12/31/2026). Without coverage on a commercial plan, the card reduces cost to $499/month (max $647/month, up to 13 fills). Tufts and Harvard Pilgrim share Point32Health's formulary architecture — verify tier and cost-share on the Tufts formulary.
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 without coverage (max $647/month, up to 13 fills; expires 12/31/2026). Excludes all government programs.
List price with no coverage — before any manufacturer savings card.
With coverage
Varies by plan tier — verify on Tufts formulary or member services. Commercially insured patients with coverage may pay as little as $25/month via the Lilly savings card.
Typical monthly copay once prior authorization is approved.
Bridge program
Lilly Mounjaro Savings Card: commercially insured patients with coverage as little as $25/mo; without coverage $499/mo (up to 13 fills, expires 12/31/2026). Not available to Medicare, Medicaid, Medicare Advantage, or government program beneficiaries.
Reduced copay through the assistance program, where eligible.
All figures are estimates; actual cost-share varies by plan tier, pharmacy, and deductible status. Confirm with Tufts formulary or member services. Medicare Part D: 25% coinsurance after deductible until the $2,100 OOP cap; MFN $245/month mid-2026. MA Medicaid (MassHealth) nominal.
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
Search the Tufts Health Plan formulary or drug list
Visit the Tufts Health Plan member portal or formulary search and enter 'Mounjaro' or 'tirzepatide.' Confirm the tier, prior authorization requirement, and cost-share for your specific plan type (commercial, Medicare, or MassHealth). Tufts and Harvard Pilgrim share Point32Health's formulary architecture, so rules track closely between the two New England plans.
- 2
Have your prescriber prepare the prior authorization
Your prescriber will need to document your confirmed T2D diagnosis (ICD-10 E11.x), A1c of 6.5% or higher within about 90 days, and a trial or failure of metformin. Massachusetts providers are generally familiar with Tufts Health Plan PA processes — verify current criteria on the Tufts formulary before submission.
- 3
Call Tufts Health Plan member services if coverage is unclear
Call the member services number on the back of your Tufts card. Ask: Is Mounjaro covered for type 2 diabetes on my plan? What tier? Is prior authorization required? What is my estimated cost-share? If you are on MassHealth through Tufts, confirm that weight-loss GLP-1s (Zepbound, Wegovy) are restricted separately from Mounjaro's diabetes coverage.
Options if Tufts Health Plan 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. Covered with PA across Tufts commercial and MassHealth plans; often placed ahead of Mounjaro in step-therapy sequences.
Trulicity (dulaglutide)
FDA-approved for T2D. GLP-1 alternative; often preferred tier with a lower list price than Mounjaro. Verify on Tufts Health Plan formulary.
Jardiance (empagliflozin) or Farxiga (dapagliflozin)
SGLT2 inhibitors approved for T2D with cardiovascular and renal benefits. May be part of step-therapy before GLP-1 approval on Tufts plans.
Zepbound (tirzepatide) — weight loss only
Same molecule as Mounjaro but FDA-approved for chronic weight management and obstructive sleep apnea — not diabetes. Has separate, more restricted coverage from Mounjaro. Massachusetts MassHealth restricts weight-loss GLP-1s including Zepbound and Wegovy.
These options are listed for information only — your own clinician decides what is appropriate for you.
❓Frequently Asked Questions
No. Tufts Health Plan does not cover Mounjaro for weight loss. Mounjaro is FDA-approved for type 2 diabetes only, and off-label weight-loss prescriptions are denied. The weight-loss tirzepatide product is Zepbound, with separate coverage. Massachusetts MassHealth restricts weight-loss GLP-1s including Zepbound and Wegovy — these are separate from Mounjaro's diabetes coverage, which remains available with PA.
MassHealth covers Mounjaro for type 2 diabetes with prior authorization at nominal cost-share. Weight-loss GLP-1s (Zepbound, Wegovy) are separately restricted under MassHealth — this does not affect Mounjaro, which is a diabetes drug. If you are on MassHealth through Tufts and have T2D, your prescriber can submit a PA for Mounjaro's diabetes indication.
Tufts Health Plan and Harvard Pilgrim are both part of Point32Health and share closely aligned formulary architecture, so Mounjaro coverage rules track closely between the two plans. Both cover Mounjaro for type 2 diabetes with PA; both operate in the MA Medicaid environment where diabetes GLP-1s are covered and weight-loss GLP-1s are restricted. The main difference is plan design — verify your specific plan's tier and criteria on the Tufts or Harvard Pilgrim formulary.
Yes, if you have commercial Tufts coverage and Mounjaro is covered on your plan, you may pay as little as $25/month via the Lilly savings card. Without commercial coverage, the card reduces cost to $499/month (max $647/month, up to 13 fills, expires 12/31/2026). The card is not available to Medicare Part D, Medicare Advantage, MassHealth, or any government program beneficiaries.
No. The 2026 Medicare GLP-1 Bridge ($50/month copay, July 1, 2026 – December 31, 2027) covers weight-loss-approved products only — Wegovy, Foundayo, and the Zepbound KwikPen. Mounjaro is excluded because it is a diabetes drug. Medicare covers Mounjaro for type 2 diabetes under standard Part D with prior authorization, specialty-tier cost-share, and the $2,100 annual OOP cap.
