Attention TRICARE beneficiaries!  
You may experience busy signals when calling the military pharmacy prescription refill interactive voice response system – or prescription refill line – Jan. 26 to Feb. 5, 2026, as the system is updated.  
Each military pharmacy’s prescription refill line may be unavailable for about two hours. If you call the prescription refill line at this time, you will hear a busy signal. Please wait and call back to complete your refill later.  
You may still use the
MHS GENESIS Patient Portal to refill your prescriptions.  
You may report issues to the DHA Global Service Center by calling 800-600-9332.

MHS GENESIS Patient Portal

The MHS GENESIS Patient Portal is the most efficient and secure method of communicating with the provider team. It provides a summary of your most recent clinical visit, lab results, upcoming appointments, and allows you to request prescription refills and renewals.

The patient portal is the preferred non-urgent way to communicate with your providers.

Medication Renewal Request

Preferred Method: Use the MHS GENESIS Patient Portal to request prescription renewals from your provider. Be sure to include the medication name(s) and current dose in your message.

Alternate Method: Call the Appointment Line at 618-256-9355, then press options 1-1 and leave a detailed message, including your name, date of birth, DOD ID number, and the medication you wish to refill.

If you have refills, they're processed through the Satellite Pharmacy, not the clinic. The phone number and prescription number on on the medication bottle. We recommend that you initiate medication refill requests a week before your current supply runs out. Please note that requests require three business days to process.

Call 618-298-7813 for request prescription refills.
