Medicare Audit

“I received notice I am being selected for a TPE (targeted probe & education) review by Novitas Medicare. I practice in New Jersey. I have gone over the LCDs and the “educational” materials they sent. My documentation seems to be aligned with what they want. Any advice for working with them to have this resolved as soon as possible? Any things to avoid? Should I have someone other than myself act as a liaison between Medicare and me?”
