How does my doctor become a TRICARE provider?
Have your doctor call the regional contractor for his or her state. Doctors may choose to become a non-network or a network provider. Your provider may also complete an online application to join the East region network or West region network.
If you aren't sure what region you're in, visit the FAQ How do I know what region I’m in?
