180-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 8—set by CMS for this code and the same in every locality. One time unit is 15 minutes, rounded to one decimal, so a 180-minute case adds 12 time units.

Report a problem

CPT 00864 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 $407.00 for a 180-minute case in Dallas, TX under the Q2 2025 release, before sequestration.

Why is there no national PFS amount for 00864?

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.
