TRICARE GLP-1 Prior Authorization Guide: Military Weight-Loss Coverage for Wegovy, Zepbound, and Saxenda (2026)

Unlike Medicare — which still statutorily excludes weight-loss drugs — TRICARE, the US military health program, does cover GLP-1 weight-management medications (Wegovy, Zepbound, and Saxenda) with an approved prior authorization. But that coverage is not universal: it applies only to beneficiaries in TRICARE Prime, TRICARE Select, or premium-based plans such as the Continued Health Care Benefit Program. And a major change already landed — as of August 31, 2025, weight-loss drug coverage ended for TRICARE For Life, direct-care-only, and NATO / Partnership-for-Peace beneficiaries. Diabetes GLP-1s (Ozempic, Mounjaro, Trulicity, Victoza) remain covered for all plans with PA when medically necessary for type 2 diabetes. This guide quotes the TRICARE and Express Scripts source language verbatim so your prescriber can address every clause. It is informational and does not constitute medical or legal advice.

Bottom line: what TRICARE covers (and who lost coverage)

• Weight-management GLP-1s (Wegovy, Zepbound, Saxenda) are covered with an approved PA for TRICARE Prime, TRICARE Select, and premium-plan members. Saxenda additionally requires a medical-necessity form.
• Diabetes GLP-1s (Trulicity, Ozempic, Mounjaro, Victoza) are covered across all plans with PA when medically necessary for type 2 diabetes.
• As of August 31, 2025, weight-loss drug coverage ENDED for TRICARE For Life, direct-care-only, and NATO / Partnership-for-Peace beneficiaries — these members pay 100% of the cost even with an approved prior authorization.

Prior-authorization criteria

• Authorization mechanics: every weight-loss agent requires a PA, a TRICARE-authorized / network prescriber, and a network pharmacy. The initial PA lasts 12 months; annual renewal requires documenting ≥ 5% baseline weight loss (adults) or ≥ 4% (ages 12 to < 18).
• Adult BMI tiers: BMI < 27 is not approved; BMI 27–29 requires at least one weight-related comorbid condition; BMI 30 or greater qualifies on its own. Adolescents 12 to < 18: Wegovy only, with BMI at or above the 95th percentile.
• Step therapy: 3 months of a generic agent (phentermine, benzphetamine, diethylpropion, or phendimetrazine) with failure to reach 5% weight loss, OR a documented contraindication to those generics. Active-duty service members pay $0.

What TRICARE says

“Weight loss medications (i.e. Wegovy, Zepbound, Contrave, Qsymia, and phentermine) are covered for beneficiaries with TRICARE Prime and TRICARE Select, with an approved prior authorization.”

— Express Scripts TRICARE Pharmacy Program FAQ. This is the load-bearing distinction versus Medicare: the category is covered, gated by PA and by plan type.

“As of August 31, 2025, coverage for weight loss medications will no longer be available for non-TRICARE Prime and non-TRICARE Select beneficiaries.”

— Express Scripts TRICARE Pharmacy Program FAQ. In practice this removed the weight-loss benefit for TRICARE For Life, direct-care-only, and NATO / Partnership-for-Peace beneficiaries, who now pay the full cost even with an approved PA.

“TRICARE still covers certain drugs (such as Ozempic, Mounjaro, Trulicity, and Victoza) for all patients to treat diabetes when medically necessary.”

— TRICARE — Weight Loss Products. The diabetes indication is unaffected by the August 2025 weight-loss change; the same molecule can be covered for type 2 diabetes while being non-covered for weight loss on the same plan.

How to appeal a TRICARE pharmacy denial

• File in writing. If you disagree with the decision, submit a signed written appeal stating why you disagree, and include a copy of the claim decision.
• Mind the 90-day deadline. The appeal must be postmarked or received by Express Scripts within 90 calendar days of the decision.
• Mail it to the Express Scripts appeals address: Express Scripts, Inc., P.O. Box 60903, Phoenix, AZ 85082-0903.
• Expect a full-course review. Express Scripts reviews the entire course of treatment, not just the single denied fill.

A note on sourcing: the detailed PA criteria above were confirmed against a US Family Health Plan administrator copy of the TRICARE PA form (dated April 2026) that mirrors the DoD / Express Scripts criteria — confirm the current form through the TRICARE Formulary Search tool before filing. Exact copays and cost tiers vary by year and plan; verify yours at tricare.mil/costs. Coverage rules change; confirm your own plan before acting.
