TRICARE is the military's health plan that provides coverage to 9.4 million active duty and retired uniformed services personnel and their family members. The TRICARE pharmacy benefit has undergone many changes in the last decade. These changes include assigning newly approved drugs to nonformulary status after regulatory approval, the addition of weight loss medications to the benefit, channel management point-of-service requirements for some medications, and copay increases. Several initiatives have resulted in significant cost avoidance to the Department of Defense (DoD). The purpose of this article is to discuss the changes to the TRICARE pharmacy benefit, describe the continual challenges, and estimate cost savings associated with implementation of these changes. DoD implemented its 3-tier Uniform Formulary in 2005. Since then, many changes have been enacted, including more extensive use of prior authorization, step therapy, and quantity limits; coverage of over-the-counter medications; the retail refund program; coverage of vaccines and smoking cessation agents; mandatory mail/military treatment facility requirements; rapid review and initial nonformulary status for newly approved innovator drugs; revisions to the compounded drug benefit; initial deployment of a new medical record system; coverage of weight loss medications; and the ability to exclude medications from the Uniform Formulary. Although the TRICARE pharmacy benefit has evolved significantly, the focus remains on the beneficiaries, with an overall goal of providing integrated, affordable, and high quality health services for the Military Health System. Challenges for the future include maximizing clinical effectiveness in the face of rising pharmaceutical costs and cost avoidance, while supporting the needs of TRICARE beneficiaries.
