What 47379 covers
47379 is the CPT unlisted code for a laparoscopic operation on the liver when the specific procedure performed has no dedicated CPT code. It is not a general substitute for a named laparoscopic liver service: laparoscopic radiofrequency or cryosurgical tumor ablation, for example, has specific codes. The operating surgeon reports it for work done through laparoscopic access. The operative report should identify the target, technique, extent of the work, and why no listed code describes the service.
Medicare assigns carrier-priced status C, so CMS publishes no national payment and the Medicare Administrative Contractor determines payment claim by claim. The contractor also sets the global period. Submit a precise procedure narrative and supporting operative documentation for review. When multiple procedures are performed in one session, Medicare’s standard multiple-procedure reduction applies: the highest-valued procedure is paid in full, and other procedures are reduced to 50%.
