Tricare now covers both treat and release and joint response ambulance services. Treat and release is when an ambulance treats you but does not take you to the hospital. Joint response is when an ambulance crew needs the help of a paramedic or intermediate EMT to give you advanced life support services. Ambulances can be network or non-network providers. Active duty troops will not pay for treat and release or joint response services, while some active duty and retiree families are subject to deductibles or copays.
