Appointments & Referrals

To make an appointment, log in to MHS GENESIS Patient Portal. (scheduling on MHS GENESIS coming soon). Use Patient Portal to send a message to your provider or call the Central Appointment Desk at: 707-423-3000.

Read the MHS GENESIS Brochure for more information.

For any care that your primary care manager does not provide, such as urgent, preventative, mental health, and specialty care, you will need a referral. Find out more about how to obtain the necessary referral and authorization.

Note: Please be aware that when a patient reverts to a military treatment facility not currently using MHS GENESIS, they must convert back to using the TRICARE Online Patient Portal.
