Basics of anesthesia billing

Anesthesia billing is very different from other types of medical billing. Every surgical procedure has a defining procedure code with a “base unit value”. During your surgery, there is a starting and ending time for the administration of the anesthesia. The acceptable standard for billing anesthesia time is 1 unit for every 15 minutes of anesthesia time. Combine the base unit with the units of anesthesia and you have your total billable units. These units are multiplied by the per unit rate to get your anesthesiologist fee. Postoperative nerve blocks are billed at a set fee.


We participate with most insurance companies, including Medicare. Community Anesthesia Associates, Ltd. will submit a bill to your insurance company. Anything not paid by your insurance, will be balance billed to you. In the case that we do not participate with your insurance company, we will submit a claim. It is possible that your insurance company will remit payment to you, reduce their payment or sometimes even deny our claim. Please contact your insurance company! If you have gone to a participating surgeon and a participating facility, you cannot choose the anesthesiologist who works at that facility. This is called a “hidden provider” and many insurance companies will adjust their payments and make an additional payment.
