Surgical procedure
About 47001: Intraoperative liver needle biopsy
A surgeon obtains a needle sample of liver tissue during another major operation when intraoperative findings or clinical need warrant histologic evaluation.
The surgeon takes a needle sample of liver tissue while performing a separate major operation. This service is used when liver tissue needs histologic assessment during that operation, such as when an abnormal-appearing liver is encountered during abdominal surgery. It is generally performed in the operating room by the surgeon carrying out the primary procedure.
Report 47001 only with the code for the primary major procedure; it is not a stand-alone liver biopsy code. Use 47000 for a percutaneous needle biopsy performed as the procedure itself, and 47100 when tissue is obtained by wedge excision rather than needle sampling. The operative report should identify the primary procedure, document that a needle biopsy was performed, and explain the clinical reason for sampling. CMS payment for this add-on falls within the primary procedure’s global period.
