## Quick answer MHS GENESIS is the modern electronic health record (EHR) system used by the Department of Defense to manage medical and dental records for all military members and their families. It replaces legacy systems like AHLTA and CHCS, providing a single, continuous health record that follows you from your initial entry into service through retirement and into the VA system.

Details

MHS GENESIS is not an insurance plan; it is the software and database infrastructure that houses your clinical data. As of 2026, it is fully deployed across all military hospitals and clinics (MTFs) worldwide, including overseas locations.

### The Patient Portal The most visible part of MHS GENESIS for beneficiaries is the **MHS GENESIS Patient Portal**. This secure website replaced TOL (TRICARE Online). Through this portal, you can: * View laboratory and radiology results. * Exchange secure messages with your primary care team. * Schedule and cancel appointments at military clinics. * Request prescription renewals at MTF pharmacies. * View your immunization records and health history.

### Accessing Your Records To log in to the portal, you must use a DS Logon (Level 2), a Common Access Card (CAC), or a Personal Identity Verification (PIV) card. Because the system is unified, if you move from a base in the **East Region (Humana Military)** to a base in the **West Region (TriWest Healthcare Alliance)**, your provider can see your entire history instantly without waiting for paper files to be mailed.

### Transition to the VA One of the primary goals of MHS GENESIS is "interoperability." It uses the Oracle Health (formerly Cerner) platform, which is the same platform being adopted by the Department of Veterans Affairs (VA) and the Coast Guard. This creates a "longitudinal" record, meaning your 2026 medical data remains accessible to the VA when you eventually separate from service, reducing the need for manual record claims.

### Privacy and Security MHS GENESIS is compliant with HIPAA regulations. While it allows for seamless sharing between military providers and authorized civilian "Joint Health Information Exchange" (joint HIE) partners, beneficiaries have the right to "opt-out" of sharing their records with civilian providers through the TRICARE or MHS GENESIS privacy settings.

## Who this affects * **Active Duty Service Members:** Accesses their readiness data and clinical history. * **Active Duty Family Members:** For those enrolled in TRICARE Prime and seen at military clinics. * **Retirees and Families:** Those receiving care at Military Treatment Facilities (MTFs). * **National Guard and Reserve:** Tracks medical readiness and line-of-duty documentation. * **Survivors:** Accesses historical family health data and ongoing care records.
