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.

60-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 7—set by CMS for this code and the same in every locality. One time unit is 15 minutes, rounded to one decimal, so a 60-minute case adds 4 time units.
CPT 00904 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 $248.49 for a 60-minute case in Dallas, TX under the Q2 2014 release, before sequestration.
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.

Why is there no national PFS amount for 00904?
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.

The anesthesia estimate uses the base units, case length, and locality conversion factor shown beside it. The PFS file shows this code is priced as anesthesia. Past releases are never edited, so these sources stay valid after CMS publishes a newer one. Our methodology explains sourcing, parsing, versioning, and how we cross-check claims before we publish them.
