What 00794 covers
Code 00794 represents anesthesia for an intraperitoneal operation in the upper abdomen involving pancreatectomy. An anesthesiologist or CRNA provides anesthesia and monitors the patient during the operative service, commonly in a hospital operating room. The procedure involves removal of pancreatic tissue; this code is distinct from anesthesia for general upper-abdominal operations without pancreatic resection.
Select 00794 for pancreatectomy; use 00790 for other upper-abdominal intraperitoneal procedures, while 00792, 00796, and 00797 identify anesthesia for partial liver resection, liver transplantation, and gastric restrictive procedures. The operative report should establish the pancreatic resection, and the anesthesia record should support the service and its time. This code has 8 base units. Medicare payment is (base units + time units) multiplied by the locality’s anesthesia conversion factor; time is reported in minutes and converted to 15-minute units to one decimal place, beginning when the practitioner starts preparing the patient and ending when the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care. Conversion factors vary by locality.

00794 billing questions
When should I choose 00794 instead of 00790?
Choose 00794 when the operation includes pancreatectomy. Code 00790 covers other upper-abdominal intraperitoneal procedures.
Does 00794 apply to every procedure involving the pancreas?
No. It is for anesthesia supporting pancreatectomy, not every procedure involving or near the pancreas. The operative report should establish pancreatic resection.
What documentation supports reporting 00794?
The operative report should identify the pancreatic resection, and the anesthesia record should support the anesthesia service and its time.
How are anesthesia units calculated for 00794?
The code has 8 base units, and Medicare adds time units before multiplying by the locality’s anesthesia conversion factor. Anesthesia time is converted from minutes to 15-minute units to one decimal place.
How does 00794 differ from 00792, 00796, and 00797?
00794 is for pancreatectomy. The other codes identify anesthesia for partial liver resection, liver transplantation, and gastric restrictive procedures, respectively.
