MHS GENESIS is the Department of Defense’s (DoD) official electronic health record system. It replaces several older systems, including the Composite Health Care System (CHCS) and the Armed Forces Health Longitudinal Technology Application (AHLTA), which date back decades.
The system creates a single, integrated, lifelong health record for each of the Military Health System’s 9.5 million beneficiaries – including active duty personnel, retirees, and their families.
This unified record follows patients across their entire care journey, whether at their home base, in deployed environments, or when transitioning to Department of Veterans Affairs (VA) care.
MHS GENESIS aims to:
- Enhance overall health outcomes
- Increase military readiness
- Improve patient safety through better information access
- Enable beneficiaries to actively manage their healthcare
What is the MHS GENESIS Patient Portal?
The MHS GENESIS Patient Portal is the secure website where beneficiaries access their health information stored in the MHS GENESIS system.
It provides registered users 24/7 access to their personal health data and offers tools to manage healthcare online.
Important: Only use the official site at https://myaccess.dmdc.osd.mil/my.logout.php3?errorcode=19. Any websites referencing MHS GENESIS that don’t end in “.mil” are not official government sites and aren’t affiliated with the DoD or MHS.
Who Can Use the Portal?
Eligibility for the MHS GENESIS Patient Portal is tied to being a Military Health System beneficiary and receiving care at a facility that has implemented MHS GENESIS. Eligible groups include:
- Active Duty Service Members
- Retirees
- Family Members enrolled in a TRICARE health plan
The system serves approximately 9.5 million beneficiaries across all DoD facilities, which completed final rollout in March 2024.
Access for Minors
Parents or legal sponsors can access their children’s health information with some age-based restrictions:
- Children 12 and under: Parents typically have full access
- Minors 13-17: Parental access is limited to appointments, messages, immunizations, and allergy information
Access to sensitive information about reproductive health, mental health, or sexually transmitted disease care may be restricted under state and federal privacy laws. Parents can request paper records through the facility’s medical records department in specific circumstances.

MHS GENESIS Rollout
The deployment of MHS GENESIS was a multi-year project replacing legacy systems across the global DoD healthcare enterprise.
The rollout began in February 2017 at four initial sites in the Pacific Northwest, including Fairchild Air Force Base. It then proceeded in 23 planned waves, bringing military hospitals and clinics online across the United States and overseas.
Key milestones included:
- California facilities (2019-2020)
- Brooke Army Medical Center in Texas (2022)
- Facilities across the National Capital Region (2023)
The seven-year deployment concluded on March 9, 2024, with the final implementation at the Captain James A. Lovell Federal Health Care Center in North Chicago, Illinois. This facility represents a unique partnership between the DoD and VA, and its successful transition marked the completion of the DoD’s MHS GENESIS rollout.
As of completion, MHS GENESIS operates at:
- 100% of DoD garrison facilities
- 138 parent military hospitals and clinics
- Over 3,600 DoD locations worldwide
- Supporting approximately 194,000 active users
Security and Privacy
Protecting sensitive patient health information is a top priority for the Military Health System. The MHS GENESIS Patient Portal incorporates measures to safeguard the confidentiality, integrity, and availability of your data.
Health information handling within MHS GENESIS is governed by federal laws and DoD regulations, primarily the Health Insurance Portability and Accountability Act (HIPAA) of 1996.
Key HIPAA components include:
HIPAA Privacy Rule
Sets national standards for protecting medical records and health information. It limits how protected health information (PHI) can be used and disclosed without patient authorization and grants patients rights over their own health information.
HIPAA Security Rule
Establishes national standards for protecting electronic PHI. It requires appropriate administrative, physical, and technical safeguards to ensure the confidentiality, integrity, and security of electronic health information.
HIPAA Breach Notification Rule
Requires covered entities to notify affected individuals, the Secretary of Health and Human Services, and sometimes the media, following a breach of unsecured PHI.
The Defense Health Agency (DHA) has specific policies implementing HIPAA requirements, with the Chief of the DHA Privacy Office serving as the designated HIPAA Privacy and Security Officer. DHA maps HIPAA Security Rule requirements to existing DoD Information Assurance policies and controls to ensure compliance.
For more detailed information on how your health information is protected, refer to the MHS Notice of Privacy Practices and the HIPAA compliance information on the official Health.mil website.
