I, and my wife have TriCare, and we also have Medicare. Both cover just about everything.
Have our own family doctor, and NONE of our Hospital, or Doctor visits have cost us A PENNY.
We live within one mile of OCEANA Naval Air Station Medical Center, Dam Neck. Portsmouth Naval Hospital is about 20 miles from here. Haven't had to use them, except for VA visits for my re-registering for Disability status...every 5 years. I think they want me to kick the bucket and save them the bother of an old Retired Guy, taking advantage of what I earned.
