Leidos and TRICARE: MHS GENESIS and Your Records

*Disclosure: TRICARE.com is an independent reference site and is not the official TRICARE program or affiliated with the Department of Defense. For official policy, visit TRICARE.mil.*

## Quick answer Leidos is a major American defense and technology firm that plays a critical role in the TRICARE ecosystem, primarily by managing the **MHS GENESIS** electronic health record system. While Leidos is not a regional insurance contractor like Humana or TriWest, they provide the underlying digital infrastructure that allows military doctors to access your records, schedule appointments, and coordinate care across the Military Health System (MHS).

In detail

Leidos impacts TRICARE beneficiaries behind the scenes by modernizing how medical data is stored and shared. Their primary involvement stems from the **Defense Healthcare Management Modernization (DHMSM)** contract, a multi-billion dollar initiative to replace legacy military healthcare legacy systems.

### MHS GENESIS Management Leidos led the "Leidos Partnership for Defense Health" (including Cerner, Accenture, and Henry Schein) to deploy **MHS GENESIS**. This system is now the standard electronic health record (EHR) for all military hospitals and clinics worldwide. * **The Patient Portal:** When you log in to view lab results, message your provider, or request prescription renewals, you are using the portal maintained by the Leidos partnership. * **Data Portability:** Leidos ensures that your medical records follow you from a base in the East Region (Humana Military) to the West Region (TriWest) without manual file transfers.

### Operational Support and IT Services Beyond records, Leidos provides technical support for various Defense Health Agency (DHA) initiatives, including: * **Cybersecurity:** Protecting the Protected Health Information (PHI) of nearly 9.6 million TRICARE beneficiaries. * **Decision Support:** Tools that help TRICARE leadership analyze healthcare costs and outcomes to determine future benefit changes. * **Telehealth Infrastructure:** Supporting the secure video platforms used for virtual appointments within MTFs (Military Treatment Facilities).

### Comparison: Leidos vs. Regional Contractors It is important to distinguish between the technology provider and the insurance administrators:

## Who this applies to * **Active Duty Service Members (ADSMs):** All medical readiness and health data are tracked via systems managed by Leidos. * **Active Duty Family Members (ADFMs):** If you receive care at a Military Treatment Facility (MTF), your records and portal access are Leidos-managed. * **Retirees using MTFs:** Retirees enrolled in TRICARE Prime or Plus who see military doctors interact daily with Leidos-maintained software. * **Providers:** Military doctors and civilian "purchased care" providers who use the Joint Health Information Exchange (jHIE) to see military records.

Common scenarios

### 1. Accessing the Patient Portal In 2026, a TRICARE Prime beneficiary in San Diego wants to check their blood pressure results from a visit to Naval Medical Center San Diego. They log into the **MHS GENESIS Patient Portal**. While the doctor is Navy and the insurance is TriWest, the software experience is maintained by Leidos.

### 2. Moving Regions A Sergeant moves from Fort Liberty (East Region - Humana Military) to Joint Base Lewis-McChord (West Region - TriWest). Because of the Leidos-led integration of MHS GENESIS, their primary care manager (PCM) at the new location can instantly view all previous clinical notes, allergies, and medications from the old location without waiting for faxed records.

### 3. Cybersecurity and Privacy A beneficiary receives a notification about a security update for their healthcare login. This layer of protection is often managed by the DHA in partnership with Leidos to ensure HIPAA compliance for the millions of users in the TRICARE system.
