Reply #2: Are you sure that your charge was just for one procedure ?

It's possible they were including multiple things but the insurance letter was only reflecting one particular item they had processed. Check the bill from the dentist versus the letter.

If they do match, it's also possible that someone midcoded or misread the procedure code so that you were charged on something different than the insurnce company got reported to them.

To avoid a stink, I'd call the dentist and tell them something didnt match and ask whether you possibly misunderstand something or an error was made. This gives them an out to deal with it themselves rather than getting in trouble (if indeed there is either a faulty or fraudulent billing). It also puts them on notice that you're checking these things.
