Surgeon providers and billing professionals use Current Procedural Terminology (CPT) codes to specify patient treatment and associated charges. In the present study, coding discrepancies between surgeons' first pass coding and employed coders' final codes were investigated. A total of 500 patients over 3 months were retrospectively analyzed for coding discrepancies. To quantify the impact of change, codes with the most accumulated discrepancies were studied and change to annual relative value unit (RVU) was determined. Final submission of codes to billing demonstrated a 161% increase in total codes by the professional coders, versus original surgeon-derived codes (1594 vs 987 CPT codes). The most common source of change between the surgeon and coder was the addition of distinct codes by the billing professional (270 patients, 54.51%). These results demonstrate the existence of coding discrepancies. Future investigation will evaluate the communication between surgeons and billing professionals.
