What 47399 covers

Surgeons report CPT 47399 for a liver procedure when no specific CPT code describes the operation performed. It is the general unlisted liver procedure code, rather than a code for a defined technique such as radiofrequency ablation. For an unlisted laparoscopic liver procedure, 47379 is the more specific code for that approach. The operative documentation and claim submission should explain the procedure and its scope.

Medicare assigns 47399 status C: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. The contractor also sets the global period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. The documentation should make the service being priced clear.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
