Wow--that sounds fishy. It makes no sense to me at all.
My mother-in-law paid $800 for a crown, only to find out it wasn't a full crown after all--another dentist told her she didn't have one. She called the one who charged her and asked about it and he immediately sent her a check for $800. Guilty, or what?
The same week she received a letter in the mail to verify how many times she had visited a PT. Some kind of audit. She was supposed to confirm going for eight visits--but she only went for three! I guess the PT had billed the insurance company for all eight! :shock:
So--based on what's happened to her--and my dwindling faith in "no one would ever lie about such a thing!!"--I'd definitely get a second opinion.
