Does UnitedHealthcare Cover Mounjaro? 2027 Medicare and Commercial Rules

By Brian Monahan Updated October 21, 2026

Reviewed October 21, 2026. Yes, UnitedHealthcare covers Mounjaro (tirzepatide) when it’s prescribed for type 2 diabetes, usually with prior authorization. It doesn’t cover Mounjaro for weight loss. That’s true for UnitedHealthcare’s commercial plans, which require a confirmed type 2 diabetes diagnosis, and for its Medicare plans, because Medicare Part D can’t cover drugs used for weight loss.

Quick answer: If you have type 2 diabetes, ask your doctor to send UnitedHealthcare a prior authorization request with your diagnosis and lab results. In 2027, Medicare drug plans can charge a deductible of up to $700, and your yearly out-of-pocket drug costs are capped at $2,400. Medicare’s $50-a-month GLP-1 Bridge for weight loss doesn’t include Mounjaro.

Plan type	Covers Mounjaro for type 2 diabetes?	Covers Mounjaro for weight loss?
UnitedHealthcare employer and individual plans	Yes, with prior authorization	No
UnitedHealthcare and AARP Medicare Advantage and Part D plans	Yes, when it’s on the plan’s drug list; prior authorization may apply	No, excluded from Part D

UnitedHealthcare commercial plans: Mounjaro prior authorization

UnitedHealthcare’s prior authorization criteria for GLP-1 diabetes drugs, effective July 1, 2026, approve Mounjaro after “confirming diagnosis of type 2 diabetes mellitus.” Your doctor shows this with one of these results:

A1C of 6.5% or higher
Fasting plasma glucose of 126 mg/dL or higher
2-hour glucose of 200 mg/dL or higher on an oral glucose tolerance test
Random glucose of 200 mg/dL or higher with symptoms of high blood sugar

The same document says Mounjaro is “not FDA approved for the treatment of weight loss” and that weight-loss drugs “are typically excluded from benefit coverage.” Approval is issued for 12 months. Source: UnitedHealthcare GLP-1 prior authorization criteria.

What about Zepbound for weight loss?

Zepbound is the same drug, tirzepatide, approved for weight management. UnitedHealthcare’s separate weight-loss drug policy, effective October 1, 2026, can approve Zepbound for a BMI of 30 or more, or 27 or more with a weight-related condition, and for moderate to severe obstructive sleep apnea. But it only applies if your employer’s plan includes weight-loss drug coverage (UHC weight-loss drug criteria). For details, see UnitedHealthcare and tirzepatide coverage.

Does Medicare cover Mounjaro?

Yes, for type 2 diabetes. CMS’s Part D manual excludes “agents when used for anorexia, weight loss, or weight gain,” even for obesity, but diabetes is a medically accepted use, so Part D plans can cover Mounjaro for it (CMS Part D Benefits Manual, Chapter 6). UnitedHealthcare’s 2026 AARP Medicare formularies list Mounjaro. Check your 2027 drug list for the tier and any prior authorization or quantity limit, because these can change each year. Our guide to drug tiers explains what each tier means.

What Mounjaro costs with a UnitedHealthcare Medicare plan in 2027

Part D standard benefit	2026	2027
Maximum deductible	$615	$700
Yearly out-of-pocket cap on covered drugs	$2,100	$2,400

Source: Medicare.gov: Part D costs. UnitedHealthcare’s Part D changes page gives the same 2027 figures. Mounjaro is a brand-name drug, so if your plan puts it on a higher tier you may reach the $2,400 cap during 2027; after that, covered drugs cost $0 for the rest of the year. You can also ask your plan about the Medicare Prescription Payment Plan, which spreads those costs into monthly payments. If your income is limited, Extra Help can lower your costs further.

Lilly’s Mounjaro savings card can’t be used with Medicare, Medicare Advantage, Medicaid or other government coverage (Lilly savings terms).

The Medicare GLP-1 Bridge doesn’t include Mounjaro

The Medicare GLP-1 Bridge is a CMS demonstration that runs from July 1, 2026 through December 31, 2027, outside the Part D benefit. Eligible people pay $50 a month for certain weight-loss drugs, and the Part D deductible doesn’t apply (CMS: Medicare GLP-1 Bridge).

Drugs included: Foundayo tablets, Wegovy injection or tablets, and Zepbound KwikPen only.
Not included: Mounjaro, Ozempic and Rybelsus.
Not eligible: people with type 2 diabetes, moderate to severe sleep apnea or fatty liver disease. Their regular Part D plan covers GLP-1s for those conditions.
BMI rules: 35 or higher; 30 or higher with certain heart failure, hard-to-control high blood pressure or kidney disease; or 27 or higher with prediabetes or a past heart attack, stroke or blocked arteries.

Mounjaro vs Ozempic coverage in 2027

Both are covered for type 2 diabetes. One difference for 2027: Medicare negotiated a price of $274 for a 30-day supply of semaglutide (Ozempic, Rybelsus and Wegovy), effective January 1, 2027 (CMS negotiated prices fact sheet). Tirzepatide (Mounjaro and Zepbound) isn’t on the negotiation lists for 2026, 2027 or 2028. Your out-of-pocket cost still depends on your plan’s tier. See UnitedHealthcare Ozempic coverage and UnitedHealthcare Wegovy coverage.

How to get Mounjaro approved by UnitedHealthcare
