CPT code 00792: Liver resection anesthesia, partial hepatectomy2026 Medicare rate & RVUs in Guam

CMS doesn’t publish an office rate for 00792 in Guam.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 00792 covers

This anesthesia service supports an intraperitoneal partial hepatectomy, in which a surgeon removes part of the liver. The procedure involves the upper abdomen and is distinct from a liver biopsy, pancreatic resection, or liver transplant. An anesthesiologist or CRNA reports the anesthesia service for the operative encounter.

Select 00792 when the operative procedure is a partial hepatectomy; 00790 is for other intraperitoneal upper-abdominal procedures not otherwise specified, while 00794 and 00796 identify pancreatic resection and liver transplantation. The operative report should establish the procedure, and the anesthesia record should support the service and its start and end times. This code has 13 base units; Medicare payment is (base units + time units) × the locality’s anesthesia conversion factor. Time is reported in minutes and converted to 15-minute units to one decimal place, beginning with anesthesia preparation and ending when the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care; the conversion factor varies by locality.
