Digestive system surgery
About 47100: Surgical liver wedge biopsy
Reports surgical removal of a wedge-shaped liver sample for tissue diagnosis, rather than a needle sample or therapeutic liver resection.
The surgeon removes a wedge-shaped piece of liver tissue for diagnostic examination, commonly during an abdominal operation when direct surgical access to the liver is available. The specimen is sent for pathology to assess suspected disease or clarify findings such as a liver lesion or diffuse tissue abnormality. This is distinct from sampling the liver with a needle and from removing liver tissue as treatment.
Report the service when the operative documentation supports an actual wedge-shaped tissue biopsy; document the specimen and the reason for sampling. A pathology examination may be reported separately by the laboratory or pathologist. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When performed in the same session as other procedures subject to the standard multiple-procedure reduction, the highest-valued procedure is paid in full and the others at 50%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
