What 00790 covers
This code covers anesthesia for intraperitoneal operations in the upper abdomen that do not fit a more specific anesthesia category. Common settings include open or laparoscopic cholecystectomy, splenectomy, and non-bariatric stomach operations. An anesthesiologist or CRNA reports the anesthesia service furnished for the operation in a hospital or other surgical facility.
Select another category for anterior abdominal wall work, upper-abdominal hernia repair, partial hepatectomy, pancreatic procedures, liver transplantation, and bariatric gastric procedures. The operative report should identify the operation and its site; the anesthesia record should support the service and document anesthesia start and end times. This code has 7 base units, and Medicare payment is (base units + time units) multiplied by the anesthesia conversion factor for the locality. Anesthesia time begins when the practitioner starts preparing the patient and ends when personal attendance ends and the patient can safely be placed under postoperative care; minutes convert to 15-minute units to one decimal place, and the conversion factor varies by locality.
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.

00790 billing questions
When should 00790 be chosen over the more specific upper-abdominal anesthesia codes?
Use 00790 for an intraperitoneal upper-abdominal operation when a more specific category does not describe the procedure. Partial hepatectomy, pancreatic procedures, liver transplantation, and bariatric gastric procedures have separate anesthesia categories.
Does 00790 cover laparoscopic upper-abdominal surgery?
Yes, when the operation is intraperitoneal in the upper abdomen and does not fall into a more specific anesthesia category. The operative approach alone does not determine the category.
Is 00790 used for abdominal wall or upper-abdominal hernia surgery?
No. Anterior abdominal wall procedures and upper-abdominal hernia repairs have other anesthesia categories; 00790 is for qualifying intraperitoneal operations.
How are time units calculated for 00790?
Anesthesia time runs from preparation of the patient until personal attendance ends and the patient can safely be placed under postoperative care. Minutes convert to 15-minute units to one decimal place.
What documentation supports reporting 00790?
The operative report should identify the procedure and its intraperitoneal upper-abdominal site. The anesthesia record should support the anesthesia service and document its start and end times.
Does 00790 include the surgeon’s procedure?
No. It represents the anesthesia service; the operating provider reports the surgical procedure.
