What 00811 covers

00811 represents anesthesia care for endoscopic examination or treatment of the lower intestinal tract. Typical cases include diagnostic or therapeutic colonoscopy and sigmoidoscopy, including biopsy or lesion removal during the endoscopy. An anesthesiologist or CRNA reports the anesthesia service separately from the endoscopist’s procedure, in an office, ambulatory surgery center, or hospital setting.

Choose 00811 for lower-GI endoscopy that is not a screening colonoscopy; use 00812 for anesthesia for screening colonoscopy and 00813 when upper and lower GI endoscopic procedures are performed in the same session. The record should identify the lower-GI procedure and its indication, whether upper endoscopy was also performed, and anesthesia start and stop times. This code has 4 base units; Medicare payment is (base units plus 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, from when the practitioner begins preparing the patient for anesthesia until the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care; 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.

00811 billing questions

How is 00811 different from 00812?

00811 is for anesthesia for lower-GI endoscopy that is not a screening colonoscopy. 00812 is the screening-colonoscopy anesthesia code.

When should 00813 be considered instead?

Use 00813 when upper and lower GI endoscopic procedures are performed during the same session. 00811 describes the lower-GI endoscopy service.

Does 00811 include the endoscopist’s procedure?

No. The anesthesia professional reports the anesthesia service, while the endoscopist reports the colonoscopy or sigmoidoscopy and any endoscopic work performed.

How are units calculated for 00811?

The code has 4 base units. Medicare adds time units, calculated from anesthesia minutes in 15-minute units to one decimal place, and multiplies the total by the locality’s anesthesia conversion factor.

What should the record support?

Document the lower-GI endoscopic procedure and its indication, any upper endoscopy performed in the same session, and the anesthesia record’s start and stop times.

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.
