What 47300 covers
A surgeon performs a hepatotomy to open and drain one or more abscesses or cysts within the liver. This is an operative service, typically performed in a hospital operating room by a general or hepatobiliary surgeon. It describes open drainage, not needle biopsy, tumor ablation, or image-guided catheter drainage through the skin.
Choose the code when the operative report documents open access to the liver and drainage of an abscess or cyst. The code covers one or more such lesions; documentation should identify the treated finding and the approach. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
