## Quick answer The "Products.htm" page is the primary index for the TRICARE Pharmacy Program’s **Formulary Search Tool**. It is used by beneficiaries and providers to check if a specific medication is covered, determine the 2026 copayment amounts, and see if a drug requires Prior Authorization or Medical Necessity documentation.

## In detail When beneficiaries refer to "Products" within the TRICARE ecosystem, they are almost always interacting with the pharmacy benefits managed by **Express Scripts**. This digital infrastructure allows you to search for drugs across all TRICARE plans, including Prime, Select, and For Life.

### How the Formulary Tool works The pharmacy search tool categories drugs into distinct tiers, which directly impacts your out-of-pocket costs. As of 2026, the tiers remain:

* **Tier 1 (Generic):** Low-cost, widely available drugs with the lowest copay. * **Tier 2 (Brand-Name / Preferred):** Higher cost than generics but preferred by the Defense Health Agency (DHA) for clinical effectiveness. * **Tier 3 (Non-Preferred):** High-cost brand-name drugs that may require a medical necessity waiver to lower the cost. * **Tier 4 (Non-Covered):** Drugs not covered by TRICARE (e.g., cosmetic drugs or some lifestyle medications).

### 2026 Pharmacy Copayments Under the current fee structure, your cost depends on where you fill the prescription:

| Medication Tier | Military Pharmacy (90-day) | Home Delivery (90-day) | Retail Network (30-day) | | :--- | :--- | :--- | :--- | | **Tier 1 (Generic)** | $0 | $13 | $16 | | **Tier 2 (Preferred)** | $0 | $38 | $43 | | **Tier 3 (Non-Preferred)** | $0 (if available) | $76 | $76 |

*Note: Active Duty Service Members (ADSMs) always pay $0 for covered drugs at all locations.*

### Key Features of the Products Search The tool provides more than just a price. It displays "Coverage Rules," which include: * **Prior Authorization (PA):** Your doctor must explain why this specific drug is needed before TRICARE pays. * **Step Therapy:** You must try one or more "Tier 1" drugs before TRICARE will cover a more expensive "Tier 2" drug. * **Quantity Limits:** Restrictions on how many pills or doses you can receive in a specific timeframe.

## Who this applies to * **Active Duty Service Members (ADSMs):** Must use military pharmacies first but can use the tool to find locations. * **Active Duty Family Members (ADFMs):** Use the tool to compare costs between Home Delivery and Retail. * **Retirees and their Families:** Impacted most by Tier 3 pricing; the tool helps identify lower-cost Tier 1 alternatives. * **TRICARE For Life (TFL) Users:** Essential for coordinating benefits with Medicare Part D (if applicable) and managing costs at 65+.

Common scenarios

**Scenario 1: Switching to Home Delivery** A retiree in the East Region (Humana Military) takes a Tier 2 blood pressure medication. By using the search tool, they see the retail cost is $43 for 30 days. By switching to Express Scripts Home Delivery, they pay $38 for a 90-day supply, saving $91 every three months.

**Scenario 2: Navigating Step Therapy** A dependent in the West Region (TriWest) is prescribed a new brand-name anti-inflammatory. The "Products" search shows it requires Step Therapy. They bring this information to their doctor, who prescribes the Tier 1 generic alternative first, resulting in a $16 copay instead of a $76 non-preferred charge.
