## Quick answer The TRICARE Pharmacy Program provides prescription drug coverage for all eligible uniformed service members, retirees, and their families. Depending on your location and the type of drug, you can fill prescriptions via military pharmacies ($0 copay), the Express Scripts home delivery mail-order service, or a network of over 50,000 retail pharmacies.
In detail
The pharmacy benefit is managed globally by **Express Scripts**. While the benefit is consistent across different TRICARE health plans (Prime, Select, etc.), your out-of-pocket costs are determined by your beneficiary status and the "tier" of the drug you are prescribed.
Where You Can Fill Prescriptions
1. **Military Pharmacies:** Usually located inside military hospitals and clinics. These offer a 90-day supply for a **$0 copay**. This is the most cost-effective option, though not all drugs are stocked. 2. **TRICARE Pharmacy Home Delivery:** Managed by Express Scripts. This is the primary method for "maintenance medications" (drugs taken regularly for chronic conditions). You receive a 90-day supply delivered to your door. 3. **Retail Network Pharmacies:** A network of over 50,000 pharmacies (including major chains and independent locals). These are best for short-term needs, like antibiotics. Coverage is limited to a 30-day supply. 4. **Non-Network Pharmacies:** You will pay the full price upfront and must file a claim for partial reimbursement. This is almost always the most expensive option.
### Understanding the Drug Tiers TRICARE categorizes drugs into four tiers which dictate your cost: * **Tier 1 (Generic):** Widely available, lowest out-of-pocket cost. * **Tier 2 (Brand Name):** Preferred brand-name drugs. * **Tier 3 (Non-Preferred):** Higher cost; usually available but more expensive because a Tier 1 or 2 equivalent exists. * **Tier 4 (Non-Covered):** Not covered by TRICARE (e.g., cosmetic drugs, some weight loss supplements).
### 2026 Pharmacy Copayments (Estimated/Current) *Note: Active Duty Service Members (ADSMs) always pay $0 for covered drugs at any internal or network pharmacy.*
| Drug Tier | Military Pharmacy (90-day) | Home Delivery (90-day) | Retail Network (30-day) | | :--- | :--- | :--- | :--- | | **Generic (Tier 1)** | $0 | $13 | $16 | | **Brand (Tier 2)** | $0 | $38 | $43 | | **Non-Preferred (Tier 3)** | $0 (if stocked) | $76 | $76 |
### Special Rules and Constraints * **Maintenance Medications:** If you live in the U.S. and use "select maintenance medications," you are generally required to use Home Delivery or a Military Pharmacy after two fills at a retail pharmacy. If you continue using a retail pharmacy for these specific drugs, you may have to pay 100% of the cost. * **Prior Authorization:** Some high-cost or specialized drugs require your doctor to submit a justification form to Express Scripts before TRICARE will cover the cost. * **Medical Necessity:** If your doctor can prove that a Tier 3 drug is medically necessary over a Tier 1 or Tier 2 drug, you may be able to get it at the Tier 2 copay rate.
Who this applies to
* **Active Duty Service Members:** Generally pay $0 for all prescriptions, but must use military pharmacies or the network. * **Active Duty Family Members (ADFMs):** Pay standard copays for home delivery and retail; $0 at military pharmacies. Includes those on TRICARE Prime and Select. * **Retirees and their Families:** Subject to the standard tiered copayments for all pharmacy types. * **TRICARE For Life (TFL) Beneficiaries:** Must use the TRICARE pharmacy benefit as their primary drug coverage, even if they have Medicare Part A and B.
Common scenarios
**Scenario 1: Management of High Blood Pressure** John is a retired Navy petty officer. He takes a generic maintenance medication for blood pressure. By switching from his local CVS to **Express Scripts Home Delivery**, he pays **$13 for a 90-day supply** (2026 rates) instead of paying $16 every month ($48 for 90 days) at his local retail pharmacy.
**Scenario 2: Acute Infection** Sarah is an active duty Army spouse. Her daughter gets an ear infection and is prescribed a 10-day course of generic antibiotics. Sarah goes to a **Network Retail Pharmacy** (like Walgreens) and pays a **$16 copay** (2026 rates) to get the medicine immediately.
**Scenario 3: Non-Preferred Brand Usage** Mark is a retiree who insists on a Tier 3 non-preferred brand medication when a Tier 1 generic is available. If he fills this via **Home Delivery**, he will pay **$76** for a 90-day supply in 2026.
