MHS GENESIS: Guide to the Military Health Record and Portal

MHS GENESIS: The Military's Modern Electronic Health Record

## Quick answer MHS GENESIS is the unified electronic health record (EHR) system used by the Department of Defense to manage medical and dental records across all military hospitals and clinics. It integrates inpatient and outpatient records into a single platform, allowing your health data to follow you from boot camp to retirement, regardless of which TRICARE region you are in.

## In detail MHS GENESIS replaced legacy systems like CHCS and AHLTA. As of 2026, it is fully deployed across all military treatment facilities (MTFs) worldwide. The system is based on Oracle Health (formerly Cerner) technology and is designed to provide a seamless "longitudinal" record for every service member and veteran.

### The MHS GENESIS Patient Portal The Patient Portal is the secure website where beneficiaries manage their care at MTFs. It is the successor to TRICARE Online (TOL). Within the portal, you can: * **View Health Data:** Access lab results, radiology reports, clinical notes, and immunization records. * **Secure Messaging:** Send encrypted messages to your primary care manager (PCM) or specialty team. * **Scheduling:** Book and cancel appointments at military clinics. * **Pharmacy:** Request prescription renewals for pickup at MTF pharmacies.

### Impact on TRICARE Regions While the EHR is unified, the contractors managing the networks remain separate. As of 2026: * **East Region:** Managed by Humana Military. * **West Region:** Managed by TriWest Healthcare Alliance (T-5 Contract). * **Overseas:** Managed by International SOS.

MHS GENESIS allows a TriWest doctor at a military clinic in California to see the same records created by a Humana Military doctor at a military clinic in Virginia without the need for manual record transfers.

### Integration with the VA and Civilian Providers MHS GENESIS is notable for its interoperability. It shares data with the Department of Veterans Affairs (VA) through the Joint Health Information Exchange (jHIE). It also connects with thousands of civilian provider systems. If you see a civilian specialist under TRICARE Select or a TRICARE Prime referral, that doctor may be able to view your MTF records—and vice versa—if they participate in the "eHealth Exchange."

## Who this applies to * **Active Duty Service Members (ADSMs):** All medical readiness data, deployment health assessments, and daily care are tracked here. * **Active Duty Family Members (ADFMs):** Those enrolled in TRICARE Prime and seen at MTFs must use the portal for all administrative tasks. * **Retirees and their Families:** Even if using TRICARE For Life, any care received at a military hospital (on a space-available basis) will be recorded in GENESIS. * **National Guard and Reserve:** Medical readiness and "Line of Duty" (LOD) documentation are centralized in this system.

Common scenarios

### Scenario 1: Checking Lab Results Jane is a TRICARE Prime enrollee seeing a PCM at Fort Belvoir Community Hospital. She has blood work done on Monday. Instead of waiting for a phone call, she logs into the MHS GENESIS Patient Portal on Wednesday. In 2026, there is no cost for this digital access; it is part of her TRICARE benefit.

### Scenario 2: Moving from East to West Region Sgt. Smith PCSs from Fort Liberty (East/Humana) to Fort Carson (West/TriWest). Under legacy systems, his paper records or digital files often arrived weeks late. With MHS GENESIS, his new doctor at Evans Army Community Hospital opens his file on day one and sees his entire history from Fort Liberty instantly.

### Scenario 3: Civilian Specialist Referral A beneficiary sees a civilian cardiologist in the TriWest network. Because the specialist participates in the CommonWell Health Alliance (which connects to GENESIS), the cardiologist pulls the patient's recent EKG results directly from the military hospital record, preventing a $200+ redundant test charge to TRICARE.
