Coverage is provided by Medicare in the United States and U.S. territories. If TRICARE for Life is used overseas, TRICARE becomes the primary payer toward medical care. By paying the annual deductible, costs and shares of TRICARE becomes your responsibility. Beneficiaries of TRICARE who stay overseas and are qualified for premium-free Medicare Part A need to have Medicare Part B in order to remain eligible for TRICARE. This is due to the fact that overseas coverage is not covered by Medicare.
The program contractor for TRICARE overseas is International SOS. This program will provide you with the needed assistance for medical providers, filing of claims, finding a provider, and authorization and assistance for medical care.
