Im rather upset. I went to a new TMJ doc in January. I had to pay up front about 900 for tests and the NTI. They said they would bill insurance for me. This has happened w. doctors in the past, you pay, they get what they can and send you a check for what they do end up getting as reimbursment. My insurance paid 1,200 last month, so Im not sure why they billed more but anyway, I called to get info on when to expect my reimbursement and they said they will keep it for future treatment. Well I hated the NTI and I never signed up for some long treatment nor have I gone back. This just makes me angry because I know a lot of times TMJ gets a cold shoulder from insurance and this kind of stuff is probably why. There are no real standards for costs of specific treatments. They basically got 2,000 for exrays and a 400 appliance.
