Specialty Drugs
High-cost, complex medications — typically biologics or injectables — that require special handling, storage, or administration.
Also known as: specialty pharmacy, biologics
Quick answer
Specialty drugs are high-cost medications used for complex conditions (rheumatoid arthritis, MS, hepatitis C, certain cancers, etc.). They often require refrigeration, special handling, or clinical monitoring. TRICARE dispenses specialty drugs through Accredo, the Express Scripts specialty pharmacy.
Why it matters
Specialty drug list prices commonly exceed $5,000–$30,000 per month. TFL coverage of these drugs at TRICARE copays is one of the most valuable financial benefits a retiree has.
Why this matters at age 65
Most MA-PD and Part D plans treat specialty drugs as coinsurance (you pay a percentage) — exposure can run thousands per month. TFL/TRICARE Pharmacy charges only a copay, not coinsurance.
When you'll encounter it
When prescribed an infused or injectable biologic, oral cancer therapy, or other specialty agent.
Impact on Medicare
Specialty drugs administered in a doctor's office or infusion center are usually billed under Part B (medical). Self-administered specialty oral or injectable drugs go through TRICARE Pharmacy.
Impact on TRICARE For Life
When the drug is Part B-administered, Medicare pays first and TFL picks up the coinsurance — often leaving $0 OOP. Pharmacy specialty drugs use TRICARE Pharmacy copay tiers via Accredo.
Impact on Medicare Advantage
MA-PD specialty tiers commonly charge 25–33% coinsurance with annual exposure in the thousands. Keeping TRICARE Pharmacy primary for the drug is usually cheaper.
Military-specific context
Accredo's TRICARE patient services line coordinates shipping, training (eg. self-injection), and refill reminders. Call 1-877-882-3324.
Common misconceptions
- "My MA plan will be cheaper for specialty drugs." — Often false — MA-PD coinsurance on specialty tiers usually exceeds TRICARE copays significantly.
Common mistakes to avoid
- Letting an MA-PD plan adjudicate a specialty drug first when TRICARE Pharmacy would have been a flat copay.
- Filling specialty meds at a retail pharmacy without going through Accredo (often results in denials).
Real-world scenario: A retiree on TFL starts Humira for rheumatoid arthritis.
Accredo ships a 30-day supply with refrigerated packaging and an injection-training call. Copay is the TRICARE brand-name tier — a small fraction of the Part D specialty-tier coinsurance equivalent.
What should I do?
- 1Ask whether your specialty drug is administered in-office (Part B) or self-administered (TRICARE Pharmacy).
- 2Use Accredo (1-877-882-3324) for all self-administered specialty drugs.
- 3If on MA-PD, compare specialty tier coinsurance to the TRICARE copay before letting the MA plan adjudicate.

- Brand-Name DrugsFDA-approved drugs sold under a manufacturer's proprietary name — middle copay tier on the TRICARE formulary.
- Creditable Drug CoveragePrescription drug coverage that CMS certifies is at least as good as standard Medicare Part D — including TRICARE Pharmacy and VA Pharmacy.
- Generic DrugsChemically identical, FDA-approved equivalents of brand-name drugs — the lowest copay tier under TRICARE Pharmacy.
- Medical NecessityA documented clinical justification that a non-formulary or restricted drug is required — allowing TRICARE to cover it at a lower tier.
- Medicare Part D and TFLWhy TFL beneficiaries do not need (and usually should not enroll in) a standalone Medicare Part D plan.
- Military Pharmacy (MTF Pharmacy)Pharmacies operated inside Military Treatment Facilities — fills formulary drugs at $0 copay for TFL beneficiaries.
- Non-Formulary DrugsDrugs not on the TRICARE preferred list — highest copay tier, often requires Medical Necessity approval.
- 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.
- 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.
- 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.
- I have other insurance besides Medicare and TFL. Who pays first?Order varies. Active-employment group insurance pays before Medicare; retiree coverage like FEHB pays after Medicare and usually before TFL. TFL is almost always last.
- 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.
