Formula (base_units + time_units) × anesthesia_cf Localis calculated this from CMS’s published inputs. Select an underlined value to see where it comes from. time_units = time_minutes / 15, rounded to one decimal place. The anesthesia conversion factor is CMS's published locality-adjusted value.

30-minute example case in Dallas, TX
Anesthesia has no single national rate—payment is (base units + time units) × the locality's anesthesia conversion factor. This example is before sequestration. Enter the service-location ZIP and case length for a local estimate.
Base units 3—set by CMS for this code and the same in every locality. One time unit is 15 minutes, rounded to one decimal, so a 30-minute case adds 2 time units.
Amount evidence: base units, time units, and the locality conversion factor, shown in the estimate. The PFS row shows this code is priced as anesthesia.

CPT 01991 is an anesthesia code, so Medicare has no single national rate: payment is (base units + time units) × the locality's anesthesia conversion factor—for example, about $111.10 for a 30-minute case in Dallas, TX under the Q1 2019 release, before sequestration.
Why is there no national PFS amount for 01991?
Its status indicator is J (anesthesia). Medicare prices this under the anesthesia formula—(base units + time units) × the locality anesthesia conversion factor—not the standard RVU formula. Choose a locality to see that factor.
