Substance use disorders include alcohol or drug abuse or dependence. Services are only covered by TRICARE-authorized institutional providers—an authorized hospital or an organized treatment program in an authorized freestanding or hospital-based substance use disorder rehabilitation facility. Treatment includes detoxification, rehabilitation in an inpatient or partial hospitalization program setting, and outpatient individual, group, and family therapy. TRICARE covers three substance use disorder rehabilitation treatments in a lifetime and one per benefit period. A benefit period begins with the first date of the covered treatment and ends 365 days later.

Emergency and inpatient hospital services are considered medically necessary only when the patient’s condition requires hospital personnel and facilities. Generally, these services may be medically necessary in certain detoxification circumstances or for stabilization of a medical condition. All treatment for substance use disorders requires prior authorization from Humana Military.
