Reader Question:

Yes, a CRNA Can Bill Anesthesia for Colonoscopy

Question: Our physicians want to add a CRNA to help with any cases, but especially with colonoscopies. Does Medicare allow a CRNA to bill for anesthesia during a colonoscopy? If so, are there certain requirements we must meet beforehand?

Answer: Yes, a CRNA can bill Medicare for colonoscopy, although some payers do not recognize anesthesia as medically necessary for endoscopies. If you file a claim, the correct code depends on the type of sedation administered.

For general anesthesia or monitored anesthesia care (MAC), report 00810 (Anesthesia for lower intestinal endoscopic procedures, endoscope introduced distal to duodenum). Reporting MAC is appropriate if the carrier recognizes that anesthesia service is medically necessary for the procedure or if you plan to bill the patient.

For moderate sedation, choose from 99148 (Moderate sedation services [other than those services described by codes 00100-01999], provided by a physician other than the health care professional performing the diagnostic or therapeutic service that the sedation supports; younger than 5 years of age, first 30 minutes intra-service time), 99149 (... age 5 years or older, first 30 minutes intra-service time), and +99150 (...each additional 15 minutes intra-service time [List separately in addition to code for primary service]). Your choice will be based on the patient’s age and the procedure length.
