Getting Care

Last Updated :

There are two things you must do before obtaining medical care at Reynolds. First, you must update your status in DEERS (Defense Enrollment Eligibility Reporting System). Second, you must enroll in TRICARE Prime or transfer your current enrollment to Fort Sill.

Defense Enrollment Eligibility 
Reporting System (DEERS)
Proper registration in the Defense Enrollment Eligibility Reporting System (DEERS) is key to receiving timely and effective TRICARE benefits. DEERS is a worldwide, computerized database of uniformed service members, their Family Members and others who are eligible for military benefits, including TRICARE.

All sponsors (active duty, retired, National Guard or Reserve) are automatically registered in DEERS. However, the sponsor must register eligible Family Members.

It is vital to keep your DEERS records updated; this includes changes in military career status, addresses, family status, i.e., marriage, divorce, births and adoptions.


To update all DEERS information, visit the local ID card facility, Building 4700, or call (580) 442-5010. The ID card facility uses an appointment system. You can call or make an appointment online. Click on the “Make Appointment” tab, select Oklahoma from the drop-down menu and click “Go,” then click on “Fort Sill” and follow the prompts. Appointments are available Monday through Friday, 8:30 to 11:30 a.m. and 12:30 to 3 p.m. To update your address and telephone number, visit and click on "Beneficiaries."
