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

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.
