Three drug benefits, one table — and who should hold which
Three drug benefits serve this site's readers: VA pharmacy ($5/$8/$11 per 30 days, $700 annual cap), TRICARE's Express Scripts ($14/$44/$85 for 90-day home delivery in 2026), and Medicare Part D (premiums plus a $2,100 cap). All three are creditable — the question is never penalties, only which benefit fits your prescribers, medications, and program.
The three benefits, one table
| VA pharmacy | Express Scripts (TFL) | Medicare Part D | |
|---|---|---|---|
| Who holds it | VA-enrolled veterans | TFL retirees & spouses | Anyone with Medicare who buys it |
| Monthly premium | $0 | $0 | ~$38.99 national base + plan variation + IRMAA at high incomes |
| Typical copays (2026) | $5/$8/$11 per 30 days; many pay $0 | $14/$44/$85 per 90-day home delivery; $16/$48 retail 30-day; military pharmacy $0 | Plan-set tiers; deductible up to $615 |
| Annual protection | $700 copay cap (PG 2–8) | Counts toward the $3,000 family cap | $2,100 out-of-pocket cap |
| Prescriber rules | VA (or authorized community) providers — won't fill outside scripts | Any prescriber | Any prescriber |
| Pharmacy access | VA pharmacies + mail; app refills | Home delivery, large retail network, military pharmacies | Plan's retail/mail network |
| Formulary | One national VA formulary | TRICARE formulary (generic-substitution rules) | Varies by plan, changes yearly |
| Creditable for Part D | Yes | Yes | — |
(CHAMPVA households have a fourth arrangement — free Meds by Mail generics plus OptumRx retail — governed by its own rule: any of the benefits above in the Part D column would end Meds by Mail.)
Drug cost comparator: VA vs. Express Scripts vs. Part D
All three routes are creditable — no late penalty rides on this choice. VA prices require VA (or authorized community-care) prescribers and formulary coverage; most brand maintenance drugs on TRICARE must move to home delivery or a military pharmacy ($0); Part D copays, deductibles, and formularies vary by plan — these are modeled estimates, not quotes.
Estimates for educational purposes only — not a quote, plan recommendation, or guarantee of costs; actual costs vary by plan, pharmacy, and formulary.

How the choices actually shake out
- VA-only veteran, VA doctors: VA pharmacy wins on price and simplicity — $700 is the worst case all year. Add Part D only for the specific reasons: civilian prescribers, a formulary gap, same-day retail needs.
- VA-enrolled veteran with mostly civilian doctors: the prescriber rule bites — every script needs VA review to fill at VA prices. Part D's premium buys friction-free retail; many split the difference, routing maintenance drugs through the VA and acute civilian scripts through a cheap PDP.
- TFL household: Express Scripts by default — any prescriber, no gap, no premium. Part D adds cost without coverage, with full penalty protection either way. The one exception: full Extra Help qualifiers should price a subsidized PDP.
- VA + TFL both (an enrolled veteran who's also a retiree): the strongest hand at the table — VA prices on VA scripts, Express Scripts for everything civilian, zero premiums, two caps.
- Anyone holding an MAPD or PDP alongside the above: you're likely paying for duplicate coverage — the creditable coverage SEP page is your next read.
