TRICARE does cover Wegovy for weight management, but only under certain plans and only after your provider completes a prior authorization. The process involves confirming your plan eligibility, meeting clinical criteria, and having your doctor submit the right paperwork to Express Scripts. Here’s how each step works.
Check Your Plan First
Not every TRICARE plan covers weight loss medications. Wegovy is covered under TRICARE Prime, TRICARE Prime Remote, TRICARE Select, TRICARE Young Adult, TRICARE Reserve Select, TRICARE Retired Reserve, the US Family Health Plan, and the Continued Health Care Benefit Program.
Two groups are excluded entirely: TRICARE For Life beneficiaries and anyone receiving direct care at military hospitals and clinics. If you fall into either category, you’ll pay 100% of the cost for Wegovy out of pocket, even if you manage to get a prior authorization approved. That’s a significant distinction, because Wegovy without insurance runs over $1,300 per month.
Three Requirements You Must Meet
TRICARE sets three conditions for covering Wegovy:
- A prescription from a network provider. Your prescribing doctor must be in TRICARE’s network. A prescription from an out-of-network provider won’t qualify.
- Medical necessity. TRICARE needs to determine that Wegovy is medically necessary and appropriate for your specific situation. This typically means meeting BMI thresholds (generally 30 or higher, or 27 or higher with a weight-related condition like high blood pressure, type 2 diabetes, or high cholesterol) along with TRICARE’s own clinical criteria.
- An approved prior authorization. Your provider must complete and submit a prior authorization form before you can fill the prescription. Without this approval, the pharmacy will reject the claim.
How the Prior Authorization Works
The prior authorization is the step where most people get stuck, but the process itself is straightforward once you know the sequence. Start by searching for Wegovy on the TRICARE Formulary website. From there, you can download and print the specific prior authorization form for the drug. Hand that form to your prescribing provider. They fill it out with your clinical details (your BMI, relevant health conditions, treatment history) and send it directly to Express Scripts, which is TRICARE’s pharmacy benefits manager. Instructions for where and how to submit are printed on the form itself.
You only need to submit one form. If you can’t find the Wegovy-specific form on the formulary tool, contact Express Scripts directly for help locating it. Your provider’s office may already be familiar with this process, so it’s worth asking if they’ve submitted TRICARE prior authorizations before.
What Your Provider Needs to Document
The strength of your prior authorization depends on what your doctor puts on the form. A bare-minimum submission is more likely to get denied. Your provider should clearly document your current BMI, any weight-related health conditions you have, and what other approaches you’ve already tried (such as diet, exercise, or other medications). If you’ve previously tried and failed on a different weight loss medication, that history is especially valuable to include, since TRICARE may require evidence that cheaper alternatives were inadequate before approving a higher-cost drug like Wegovy.
Talk to your provider before they submit the form. Make sure they understand you want Wegovy specifically and that they’re prepared to justify it based on your health profile. A provider who writes a detailed clinical rationale gives you a much better shot at first-pass approval than one who checks a few boxes and sends it off.
Staying on Wegovy After Approval
Getting the initial authorization isn’t the end of the process. TRICARE requires that you continue to meet prior authorization requirements to keep your coverage active. This means ongoing documentation that the medication remains medically necessary and appropriate for your treatment. Your provider will likely need to resubmit authorization paperwork at regular intervals, and you should expect TRICARE to look at whether the medication is actually working for you (typically measured by weight loss progress) before renewing approval.
Stay in close contact with your prescribing provider throughout treatment. If you switch doctors, move, or change TRICARE plans, your authorization may need to be resubmitted.
What You’ll Pay Out of Pocket
Once approved, your copay depends on whether Wegovy is classified as a brand-name formulary drug or non-formulary drug, and where you fill it. For 2026 and 2027, TRICARE’s pharmacy copays for most beneficiaries break down like this:
- Home delivery (up to 90 days): $38 for brand-name formulary drugs, $76 for non-formulary drugs
- Retail network pharmacy (up to 30 days): $43 for brand-name formulary drugs, $76 for non-formulary drugs
Medically retired sponsors and certain survivors pay less: $20 for brand-name formulary through home delivery, $24 at retail. Home delivery is the better deal for most people, since you’re getting a 90-day supply for less than the cost of a single 30-day retail fill. You can set up home delivery through Express Scripts once your prior authorization is approved.
If Your Authorization Gets Denied
A denial isn’t necessarily the final answer. Common reasons for denial include incomplete paperwork, insufficient documentation of medical necessity, or not meeting the specific clinical criteria TRICARE requires. If you’re denied, ask Express Scripts for the specific reason. Your provider can then address the gap and resubmit. In many cases, a more detailed clinical justification or additional documentation of failed alternative treatments is enough to overturn an initial denial.
You also have the right to appeal through TRICARE’s formal appeals process. This involves submitting a written request with supporting medical documentation explaining why Wegovy is necessary for your care. Your provider’s office can help you assemble this, and many have staff experienced with insurance appeals for weight management medications.
