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 13—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 00670 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 $508.75 for a 180-minute case in Dallas, TX under the Q4 2025 release, before sequestration.

Why is there no national PFS amount for 00670?

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.

    Medicare Advantage, Medicaid or commercial volume, or the exact place of service: CMS publishes only the facility vs non-facility split, so the Office (non-facility) share does not identify urgent care or any other specific setting.
    Note
    The dataset suppresses rows under 11 beneficiaries. Specialty groups with fewer than 30 observed clinicians are omitted, so the shares can fall short of 100%.
