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.

How and when to schedule a QNFT

QNFT walk-in hours for both military protective masks and industrial respirators are from 9-11 a.m. every Tuesday and Wednesday. Per IAW AFI 48-137, you only need to have a military gas mask QNFT once per lifetime or upon arrival at the first permanent duty station. We will do another QNFT if:

  • You geta new size or type of mask
  • You gain or lose 10% or more of body weight after your initial QNFT
  • You have extensive dental work, facial surgery, scarring, or disfigurement.

Industrial respirators require fit testing and training each year.
