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.

00812 billing questions

How is 00812 distinguished from 00811?

00812 is for anesthesia for a screening colonoscopy. Use 00811 for lower-intestinal endoscopy performed for a diagnostic or therapeutic indication rather than screening.

What if an upper endoscopy is performed during the same anesthesia encounter?

When both upper and lower GI endoscopic procedures are performed in the same anesthesia encounter, consider 00813 rather than 00812.

Does the endoscopist’s procedure include the anesthesia service?

The endoscopist reports the colonoscopy, and the anesthesia professional reports the anesthesia service on the anesthesia claim.

How are anesthesia units calculated for 00812?

The code has 3 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.

How does Medicare pay when an anesthesiologist medically directs a CRNA?

Medicare pays each professional 50% of the allowance for the personally performed service.

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.
