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

What 00812 covers

Code 00812 represents anesthesia care for a screening colonoscopy, an endoscopic examination of the colon performed to screen for colorectal disease. An anesthesiologist or CRNA may provide the service in an endoscopy unit, ambulatory surgery center, or hospital; the anesthesia professional reports the anesthesia, while the endoscopist reports the examination. Average-risk and high-risk screening colonoscopies are commonly represented by G0121 and G0105, respectively.

Choose 00812 for a screening colonoscopy; use 00811 for lower-intestinal endoscopy performed for a diagnostic or therapeutic indication, and 00813 when upper and lower GI endoscopic procedures are performed in the same anesthesia encounter. The anesthesia record should support the screening indication, procedure performed, practitioner attendance, and anesthesia start and stop times. This code has 3 base units. Medicare payment is (3 base units + time units) × the locality’s anesthesia conversion factor; time is counted in minutes from preparation for anesthesia until personal attendance ends and the patient can safely be placed under postoperative care, then converted to 15-minute units to one decimal place.
