TRICARE Retail Network Pharmacy
Civilian pharmacies (chains and independents) contracted with Express Scripts to fill TRICARE prescriptions at network copays.
Also known as: retail network, in-network pharmacy
Quick answer
TRICARE retail network pharmacies are civilian pharmacies — major chains (CVS, Walgreens, Walmart, Kroger, Publix, etc.) and many independents — under contract with Express Scripts to fill TRICARE prescriptions at standard network copays. The network covers tens of thousands of pharmacies nationwide.
Why it matters
Retail network is the right choice for short-term medications (antibiotics, post-op pain) and for any time Home Delivery is impractical. Copays are higher than Home Delivery but far below non-network rates.
Why this matters at age 65
Confirm your favorite local pharmacy is in network — most are, but a few independents are not. Walgreens dropped out of the TRICARE network in 2024; verify current status before assuming.
When you'll encounter it
Acute prescriptions, vacation refills, anything you can't wait 7–10 days for.
Impact on Medicare
None directly. The pharmacy bills Express Scripts, not Medicare.
Impact on TRICARE For Life
Network copay applies — typically a few dollars for generics, more for brands.
Impact on Medicare Advantage
If you have MA-PD, the pharmacy will try to bill the MA-PD plan first. You can instruct them to bill TRICARE only — usually cheaper.
Military-specific context
Find a network pharmacy on militaryrx.express-scripts.com. The same chain may have some locations in-network and some out — confirm at the specific store.
Common misconceptions
- "All big chains are in the TRICARE network." — Not always — Walgreens left the network in 2024. Confirm before filling.
Common mistakes to avoid
- Assuming your old pharmacy is still in-network without verifying.
- Refilling 30-day at retail instead of moving to 90-day Home Delivery for maintenance drugs.
Real-world scenario: A retiree gets a 10-day antibiotic prescription on a Friday evening.
She fills at the in-network CVS for a small generic copay — appropriate use of retail network for a short, acute course.
What should I do?
- 1Confirm your preferred pharmacy is in the TRICARE network at militaryrx.express-scripts.com.
- 2Use retail network for acute, short-course meds.
- 3Move 90-day maintenance refills to Home Delivery for lower cost.
