FAQs20
- Should I use the VA pharmacy or TRICARE Pharmacy?You can use both. VA fills prescriptions written by VA providers; TRICARE Pharmacy fills prescriptions written by any provider. Use whichever is cheaper and more convenient for each medication.
- What are the TRICARE Pharmacy copays for retirees?MTF pharmacy: $0. Home Delivery (90-day): low. Retail network (30-day): higher. Non-network: highest and requires a paper claim. Exact amounts adjust annually.
- Pharmacy — FAQ categoryTRICARE Pharmacy (Express Scripts) remains your prescription benefit after 65 — and it's creditable coverage, so you don't need Medicare Part D. Here's when that changes.
- Should I enroll in Medicare Part D?No, for almost every TFL beneficiary. TRICARE Pharmacy (Express Scripts) is creditable coverage and cheaper than most Part D plans. Adding Part D usually costs more without adding benefit.
- What are the biggest mistakes retired military make at 65?Declining Part B, missing the IEP, ignoring DEERS, enrolling in Part D unnecessarily, and assuming MTF access continues. Each can cost thousands or end TFL.
- Do I need a Part D drug plan?No. TRICARE Pharmacy (Express Scripts) is creditable coverage. Enrolling in a standalone Part D plan can disrupt your TRICARE benefits.
- Do I have to file claims myself?Almost never. Medicare and TFL claims cross over automatically. The exceptions are non-network pharmacy, overseas care, and providers who opt out of Medicare.
- Where can I fill prescriptions on TFL?MTF pharmacy (free), TRICARE Pharmacy Home Delivery (Express Scripts, lowest copays for 90-day supplies), or any in-network retail pharmacy.
- What actually changes the day I turn 65?Your TRICARE Prime/Select ends, Medicare A and B become primary, TRICARE For Life turns on as your secondary, and your MTF access drops to space-available.
- What is Extra Help and do I need it on TFL?Extra Help (LIS) lowers Part D drug costs for low-income beneficiaries. TFL beneficiaries usually don't need it because TRICARE Pharmacy is already very low cost — unless you also enroll in a Part D plan.
- What is 'creditable coverage' for Part D?Drug coverage that's at least as good as standard Part D. TRICARE Pharmacy is creditable, so you can skip Part D without owing a late-enrollment penalty later.
- What if my drug isn't on the TRICARE formulary?Non-formulary drugs cost more. Your doctor can request a medical-necessity exception so it's covered at the formulary copay.
- What is a pharmacy prior authorization?Some drugs (high-cost specialty, opioids, certain brand-names) require Express Scripts to approve before TRICARE will pay. Your doctor submits the request.
- Should I enroll in a Medicare Advantage plan that includes Part D (MAPD)?Only if the MA plan otherwise makes sense for you. The Part D piece duplicates TRICARE Pharmacy — but you keep TRICARE Pharmacy as a fallback. Don't enroll just for the drug coverage.
- I accidentally enrolled in a Part D plan. What now?Disenroll during AEP (Oct 15 – Dec 7) for the next year, or use an SEP if you qualify. TRICARE Pharmacy still works — but stop paying the duplicate Part D premium.
- Who is eligible for TRICARE For Life?Retired uniformed service members, eligible spouses and widows/widowers, certain former spouses, and Medal of Honor recipients — all entitled to Medicare Part A and enrolled in Part B, with current DEERS status.
- Is there an enrollment fee for TRICARE For Life?No. TFL has no enrollment fee and no monthly premium. The only premium you pay is for Medicare Part B.
- Who pays first, Medicare or TRICARE For Life?Medicare pays first for any service it covers. TFL pays second. The claim usually crosses over automatically — you should never pay out of pocket up front.
- Does TRICARE For Life work overseas?Yes. Overseas, TFL acts as your primary payer because Medicare generally doesn't pay outside the U.S. You'll usually pay the provider up front and file a paper claim with TFL overseas.
- Will I lose TRICARE For Life if I join Medicare Advantage?No. As long as you keep Medicare Part B, TFL stays. Inside an MA plan, MA becomes primary and TFL becomes a secondary wraparound for in-network MA cost-shares.
