Anesthesia Conversion Factors

The anesthesia conversion factors for each calendar year are listed by payment locality and are effective for the date the service was provided. The participating physician anesthesia conversion factor is listed first, the non-participating physician anesthesia conversion factor is second, and the limiting charge is listed in the third column.

The non-participating physician conversion factor is computed at 95 percent of the participating physician conversion factor. The limitation in the statute requires that Qualified Nonphysician Anesthetist services not exceed the conversion factor for physicians' anesthesia services.
