Getting Care


On Jan. 13, 2024, the Department of Defense’s new electronic health record (EHR), MHS GENESIS, launched here at Naval Hospital Guam. MHS GENESIS has replaced TRICARE Online at this facility. 


MHS GENESIS is the new EHR that provides you and your providers with enhanced, secure technology to manage your health information. When fully deployed, MHS GENESIS will be the single health record for service members, veterans, and their families. >>Learn More about MHS GENESIS

What is the MHS GENESIS Patient Portal?

Along with the new EHR, the MHS GENESIS Patient Portal is a secure website available 24/7 that gives you access to your health information. Through the MHS GENESIS Patient Portal, you can:
  • View health information, including laboratory and radiology results  
  • Schedule appointments
  • Communicate securely with care team
  • Request prescription renewals
  • Complete intake and screening forms in advance of appointments
  • Access a health library
The MHS GENESIS Patient Portal is replacing the TRICARE Online Secure Patient Portal.

What does this mean for me?

MHS GENESIS and the MHS GENESIS Patient Portal have replaced TRICARE Online, including the patient portal and secure messaging, at this facility.
  • If you had a current TRICARE Online account, it was migrated to MHS GENESIS on Jan. 13, 2024. No action is necessary by you.
  • If you don’t already have a TRICARE Online account, you can log onto your Common Access Card or DS Logon Account.
  • If don’t have a DS Logon Account or if you have questions about DS Logon, visit the milConnect website or call 1-800-538-9552.

What happens next?
