When writing prescriptions for your TRICARE  beneficiaries, please remember that some medications require prior authorization. These include brand-name drugs with generic equivalents, drugs that are new to the market and not yet reviewed for Department of Defense (DoD) formulary inclusion and certain  other drugs identified by the DoD.
 
Brand-name drugs with generic equivalents can be dispensed only if you can establish medical necessity, and they will only be covered by TRICARE if you obtain prior authorization. In addition, active duty service members (ADSMs) and other eligible beneficiaries can receive non-formulary drugs at a lower cost when medical necessity is established. If medical necessity is established, ADSMs may receive non-formulary medications at retail network pharmacies or through the TRICARE Mail Order Pharmacy at no cost. Other eligible TRICARE beneficiaries may receive them at the formulary medication cost.
