## Quick answer TRICARE beneficiary services are the support systems—provided by regional contractors and the Defense Health Agency—that help you manage your healthcare coverage. These services include finding a provider, checking claim status, resolving billing issues, and updating your information in DEERS. Depending on where you live, these services are handled by **Humana Military (East)**, **TriWest (West)**, or **International SOS (Overseas)**.

In detail

Beneficiary services are divided into three primary categories: administrative management, clinical resources, and financial oversight. Since the transition to the T-5 contract on January 1, 2025, TriWest has assumed all West Region beneficiary services, while Humana Military continues to manage the East.

### 1. Regional Contractor Services (East & West) Your regional contractor is your primary point of contact for day-to-day operations. Their beneficiary service portals allow you to: * **Search for Providers:** Locate TRICARE-authorized doctors, specialists, and hospitals within your region. * **Manage Referrals and Authorizations:** Most TRICARE Prime beneficiaries require a referral for specialty care; beneficiary services allow you to track the status of these requests. * **Claims Processing:** View "Explanation of Benefits" (EOB) statements and check if a claim has been paid. * **Secure Messaging:** Communicate directly with customer service representatives regarding specific health benefits.

### 2. Pharmacy Services Managed by **Express Scripts**, pharmacy beneficiary services allow you to manage your prescriptions globally. * **Home Delivery:** Order maintenance medications (90-day supplies). * **Price Check:** Use the "Price a Medication" tool to see 2026 copays for generic, brand-name, and non-network drugs. * **Formulary Search:** Ensure your specific medication is covered before visiting a pharmacy.

### 3. DEERS (Defense Enrollment Eligibility Reporting System) While contractors manage care, the Department of Defense manages *eligibility* through DEERS. Beneficiary services at the DEERS level include: * Updating addresses and contact info (failure to do so can lead to a loss of coverage). * Adding family members (newborns, spouses). * Managing "MilConnect" logins to view proof of coverage.

Summary of Regional Service Contacts (2026)

## Who this applies to * **Active Duty Service Members (ADSMs):** Rely on beneficiary services for travel authorizations and referrals when away from their primary duty station. * **Active Duty Family Members (ADFMs):** Use these services to navigate TRICARE Select or Prime and manage specialist appointments. * **Retirees and Their Families:** Essential for tracking 2026 enrollment fees and managing TRICARE For Life (TFL) transitions. * **National Guard and Reserve:** Use beneficiary services to verify coverage during periods of activation or when paying monthly premiums for TRICARE Reserve Select.

Common scenarios

### Scenario 1: Moving from Virginia to California A Navy family moves from the East Region (Humana Military) to the West Region (TriWest) in 2026. Their primary beneficiary service task is updating their address in DEERS and then visiting the TriWest website to select a new Primary Care Manager (PCM) in the West network.

### Scenario 2: Contesting a Medical Bill A TRICARE Select beneficiary receives a bill for $500 for an outpatient procedure. By logging into the **Humana Military** beneficiary portal, they find their EOB (Explanation of Benefits) showing the 2026 deductible was met and their actual cost-share should only be $91. They use the contractor's "Customer Service Chat" to initiate a claim review.

### Scenario 3: Specialty Care Referral A TRICARE Prime enrollee is referred to a cardiologist. They use the **TriWest** self-service portal to download the "Authorization Letter," which tells them exactly which doctor they can see and the expiration date of the referral.
