There are nearly 11,000 CPT codes. In 2023, 225 new codes were added, 75 were deleted, and another 93 were revised.5
According to the AAPC, every section of the coding guidelines was changed except for anesthesia. “The most significant changes are to the evaluation and management (E/M), percutaneous pulmonary artery revascularization, hernia repairs, lab and pathology, and COVID-19 vaccination codes.” There are also new appendices for taxonomy and artificial intelligence and “synchronous real-time interactive audio-only telemedicine services.” To say coding is complex is an understatement. Just staying on top of the changes could be a full-time job.
According to the American Medical Association, some of the top coding errors include unbundling, upcoding, incorrect appending of modifiers, overuse of modifier 22, not including documentation for unlisted codes, and not referencing National Correct Coding Initiative (NCCI) edits for multiple code reporting.6
