Im getting denials from Medicare for CPT Code 96375. They are stating that it is an unbillable code. I made sure the claim had the proper Initial Code, but it still is denying. Any insight would be great. Also, i know this code is Modifier 59 exempt, but i found a claim that paid this code that had modifier 59 on it. So that makes absolutely no sense! Not sure if it was added by the coder or initial biller. Please help!
