1. Where to fill, and what it costs

Express Scripts runs the TRICARE pharmacy benefit. These are retiree and family copays. The Defense Health Agency says they stay in effect through December 31, 2027.

DrugHome delivery, 90 daysRetail network, 30 days
Generic$14$16
Brand-name$44$48
Non-formulary$85$85

A brand-name drug at home delivery costs $44 for 90 days; at retail, three 30-day fills cost $144.

2. The home delivery rule

Everyone except active duty, TRICARE For Life included, must refill certain brand-name maintenance drugs through home delivery or a military pharmacy. You get a letter after the first retail fill and another after the second. On the third, you pay 100%. The rule doesn’t apply if you live overseas, or if other health insurance with drug coverage, such as FEHB, pays first. The drug list is at tricare.mil/maintenance.

To switch, call Express Scripts at 877-363-1303 or have your doctor send the prescription to home delivery.

3. Prior authorization

Some drugs need Express Scripts to approve them first: drugs with age or sex limits, brand-name drugs that have a generic, and amounts above the normal limit.

4. Quantity limits and step therapy

5. How to appeal

Ask your doctor for a letter explaining why you need the drug. That’s usually what wins an appeal.

6. GLP-1 drugs and TRICARE For Life

TRICARE For Life stopped covering GLP-1 drugs such as Wegovy and Zepbound for weight loss on August 31, 2025. They’re still covered for diabetes when prior authorization criteria are met. Your options are in the Medicare GLP-1 bridge and TRICARE For Life.

How long does TRICARE prior authorization take?

Express Scripts usually decides about 10 days after it gets the request from your prescriber. Your prescriber can send it electronically, by fax or by phone. The approval letter shows how long it lasts.

How do I appeal a TRICARE pharmacy denial?

Send Express Scripts a signed, written request for reconsideration within 90 days of the decision. Say why you disagree and include a copy of the denial. Mail it to Express Scripts, Inc., P.O. Box 60903, Phoenix, AZ 85082-0903. If it’s denied again, the letter tells you the next step.

Does TRICARE For Life cover Wegovy or Zepbound for weight loss?
