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 5—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.

Report a problem

CPT 00834 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 $183.15 for a 60-minute case in Dallas, TX under the Q4 2025 release, before sequestration.

Why is there no national PFS amount for 00834?

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.
