Mounjaro, with its active ingredient tirzepatide, has helped many people with type 2 diabetes achieve better blood sugar control while also promoting significant weight loss as a common side benefit. For those without diabetes but struggling with obesity, the medication’s appetite-suppressing effects make it appealing for off-label use. Military families covered by TRICARE often ask whether this powerful option fits into their benefits, especially when prescribed primarily to manage weight.
TRICARE follows federal guidelines that distinguish between coverage for diabetes treatment and coverage for weight loss alone. Recent policy updates, effective August 31, 2025, tightened rules for weight management drugs across certain plans. This change aligns with regulations limiting non-essential uses while protecting access for medically necessary cases.
This article outlines current TRICARE rules for Mounjaro when used for weight loss, including plan-specific details, prior authorization steps, costs, and alternatives. It helps beneficiaries understand their options and prepare for informed discussions with providers.
What Is Mounjaro and Its Role in Weight Management?
Mounjaro is a weekly injection that activates GLP-1 and GIP receptors to regulate insulin, slow digestion, and reduce hunger. Approved for type 2 diabetes, it frequently leads to 15-21% body weight loss in studies when paired with lifestyle changes. Many pursue it off-label for obesity due to these robust results.
The same molecule is branded Zepbound when FDA-approved specifically for chronic weight management. TRICARE evaluates both under pharmacy benefits managed by Express Scripts.
Coverage hinges on the diagnosis, plan type, and meeting clinical criteria.
Does TRICARE Cover Mounjaro for Weight Loss?
Does TRICARE Cover Mounjaro for Weight Loss? TRICARE does not cover Mounjaro when prescribed solely for weight loss in most cases as of 2026. The Defense Health Agency updated rules effective August 31, 2025, ending coverage for weight management drugs—including Zepbound and off-label Mounjaro—when obesity is the sole or major condition for beneficiaries not enrolled in TRICARE Prime or TRICARE Select.
TRICARE Prime and TRICARE Select (including premium-based plans like TRICARE Reserve Select, Retired Reserve, Young Adult, and Continued Health Care Benefit Program) still cover certain weight loss medications with approved prior authorization and clinical criteria met. However, Mounjaro itself is not FDA-approved for weight loss—only diabetes—so pure weight-focused prescriptions face denial or full out-of-pocket costs.
TRICARE For Life, direct care-only beneficiaries, and certain other groups lost coverage for weight loss indications entirely after the 2025 change. Diabetes treatment remains covered across plans.
Coverage for Diabetes vs Weight Loss
When Mounjaro is prescribed for type 2 diabetes, TRICARE covers it reliably with prior authorization and medical necessity forms (for formulary copay and military pharmacy access). This applies to all eligible beneficiaries, including TRICARE For Life.
For weight loss alone, coverage is limited to Prime and Select enrollees under strict rules—no longer available for non-Prime/Select after August 31, 2025. Zepbound (same drug, weight indication) follows similar restrictions.
Prior authorizations for weight loss from before the change are no longer valid—new evaluations are required.
Prior Authorization and Clinical Criteria
To seek coverage under eligible plans, your provider submits a prior authorization to Express Scripts. This includes proof of BMI (typically 30+ or 27+ with comorbidities), failed prior weight loss attempts, and medical necessity.
Step therapy may require trials of other approaches first. Approval often requires documented weight reduction (e.g., 5% in initial months) for continuation.
Denials can be appealed with additional evidence from your doctor.
Costs When Covered or Not
Covered fills under Prime/Select often carry specialty tier copays or coinsurance—around $38–$100 for a 30-day supply via home delivery, varying by status and plan. Military pharmacies may offer lower rates with proper forms.
Without coverage, costs reach $1,000+ monthly. Manufacturer savings cards help some commercially insured users, but TRICARE beneficiaries face restrictions on these programs.
Explore patient assistance if uninsured or ineligible.
Alternatives Covered by TRICARE
For diabetes management, Ozempic, Trulicity, and Victoza remain covered with authorization. These GLP-1 options provide glucose control and some weight benefit.
Weight-focused alternatives like Wegovy may gain approval under Prime/Select with similar prior authorization. Older drugs such as phentermine (short-term) or Contrave face their own criteria.
Lifestyle programs, nutrition counseling, and bariatric referrals receive support under many plans.

Steps to Check Your Coverage
Log into your beneficiary web portal or call Express Scripts/TRICARE pharmacy support. Use the formulary search tool to check tirzepatide/Mounjaro/Zepbound status.
Discuss with your provider whether diabetes diagnosis applies or if weight indication fits eligible plans. Submit required forms promptly.
Track appeals or alternatives if initial requests face denial.
Lifestyle Support Alongside Medication
Focus on nutrient-dense meals with protein and fiber to manage appetite changes safely. Regular activity enhances metabolic benefits.
Track weight and health markers to demonstrate progress during reauthorizations. Nutrition counseling may be covered.
These steps support any approved treatment and improve overall outcomes.
Summary
TRICARE does not cover Mounjaro for weight loss in most cases as of 2026, particularly under TRICARE For Life, direct care-only, or non-Prime/Select plans after the August 2025 changes. Prime and Select may cover weight management drugs like Zepbound with strict prior authorization, but Mounjaro itself remains tied to diabetes indications.
Diabetes treatment with Mounjaro receives reliable coverage across plans when criteria are met. Costs vary widely without approval.
Verify your specific plan details and work with your provider to explore covered paths or alternatives that align with your needs.
