What 00797 covers

This code covers anesthesia for intraperitoneal bariatric operations in the upper abdomen that reduce stomach capacity, including gastric bypass and sleeve gastrectomy. An anesthesiologist or CRNA reports the anesthesia service for the qualifying operation in a facility setting. The patient’s obesity alone does not make this the appropriate anesthesia code; the operation performed determines selection.

Choose this code for the bariatric operation rather than 00790, which covers other intraperitoneal upper-abdominal procedures; procedure-specific codes apply to partial hepatectomy, pancreatectomy, and liver transplantation. The operative report should identify the bariatric procedure, and the anesthesia record should document the practitioner’s service and anesthesia start and end times. Medicare payment uses 11 base units plus time units, multiplied by the locality-specific anesthesia conversion factor, which varies by locality. Report anesthesia time in minutes from when preparation begins until the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care; CMS converts it to 15-minute units to one decimal place.

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.

00797 billing questions

When should I choose 00797 instead of 00790?

Use 00797 for anesthesia for a qualifying bariatric operation in the upper abdomen, such as gastric bypass or sleeve gastrectomy. Use 00790 for other intraperitoneal upper-abdominal procedures covered by that code.

Does the surgeon’s procedure code replace 00797?

No. The surgeon reports the operative procedure, while the anesthesia professional reports 00797 for anesthesia for the qualifying bariatric operation.

Do both gastric bypass and sleeve gastrectomy qualify?

Yes. Anesthesia for qualifying upper-abdominal gastric bypass and sleeve gastrectomy procedures is reported with 00797.

What should the records show?

The operative report should identify the bariatric procedure performed. The anesthesia record should support the anesthesia service and document its start and end times.

How are time units calculated?

Record anesthesia time in minutes and convert it to units of 15 minutes, computed to one decimal place. Time starts when the anesthesia practitioner begins preparing the patient and ends when the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
