  • Enroll into a TRICARE plan or transfer enrollment to the 61 MDS

The Outpatient Records Department is responsible for managing and safeguarding medical records for all patients assigned to the 61 MDS. The Release of Information section provides copies of medical records to patients and other agencies upon request. Routine record requests will be completed within 20 working days. Upon receipt of a member’s PCS orders, the complete medical record will be mailed to the member's gaining military treatment facility. If an active duty member retires or separates, the medical and dental record is sent to the Service Treatment Record Cell located in San Antonio, Texas. The Referral Management Center processes patient specialty referrals requested by the military treatment facility primary care manager. The RMC will route your referral to the requested specialty within the MTF or to Health Net Federal Services for treatment by an off-base specialist.

  • It is important to keep your DEERS information up to date (e.g. home address, e-mail, phone numbers, dependent information etc.). You can call 800-583-9552 or visit DEERS for assistance.
  • You can contact Health Net Federal Services for any referral related questions by calling 844-866-WEST (9378) or visit the MHS GENESIS to view your authorization.
  • Please have the network specialist fax your results to the Referral Management Center at 310-653-6453.

In some cases, we can also refer our patients to nearby MTFs for services that we cannot accommodate.
