Arthroplasty

“In many cases requiring an arthroplasty of the proximal interphalangeal joint (PIPJ) 5th digit (especially when associated with a heloma molle), I often do an arthroplasty PIPJ, flexor lengthening and a partial syndactylization (advancing the webspace but differently than the description of Ruiz-Mora). I have always simply billed for an arthroplasty PIPJ 5th toe. Now I have been forced to pay attention to coding because of my EMR program. Should I have been billing this differently for all these years?”
