If beneficiaries live overseas and need air ambulance services (aeromedical evacuation or "air evac"), TRICARE only pays if the transport is medically necessary and to the closest, safest location for medical care. Retirees overseas have to pay for the service up-front and then file a claim for reimbursement. If you are planning to live or travel overseas, you may wish to consider other options for coverage of air transport for circumstances not covered by TRICARE. Also, active-duty family members (ADFMs) using TRICARE Standard may have to pay up front for the air evacuation; the evacuation must be medically necessary; and must be to the nearest facility capable of providing the needed care in order for TRICARE to cost-share on the aeromedical evacuation. For more information about receiving care overseas, visit the TRICARE Overseas Program webpage.
