I used to have Tricare, as my dad was in the military for 20 years. Tricare, although a very nice insurance, can be kinda messy and screw up a lot. As you have experienced. I've experienced having to call several people in the tricare office and hospital offices about bills that were supposed to be payed, weren't filed right, etc... but with patience, they will fix their mistakes. Good luck on everything, and i am glad to hear that you don't have to pay that bill. One time, i went to the psych ward for a week and the usual copay for tricare was around $240 (cause thats what i had to pay several times i went) and one of the bills came back and they expected me to pay over $9,000! :O It took me several WEEKS to get that one straightened out. Turns out they filed my visit as "outpatient" instead of "inpatient." It was so retarded. But a few months later, I got the correct copay bill. It just takes patience.
