We full time and have a doctor at our home of records. We use Express Scripts to handle all our medications except for controlled meds which we use CVS for. They mail them to wherever you are and will maintain a one year order from your doctor that they will fill automatically. Our doctor will only do 3 months at a time so we have to call when we need a refill. Wife has been going thru Chemo for the last 4 years and right now in Florida for the winter we have a Oncologist here and one in MI. She's on Medicare and I'm still on Tricare and if I need to see a doctor on the road most urgent care centers will take Tricare or a call to Tricare center for the region can give you a list of doctors in your area you can call to get an appointment.
