CPT 00540
Priced using anesthesia methodology
00540 · PFS Q1 2024 · Historical
See your local estimate for a sample 180-minute case.
CPT 00540 is an anesthesia code, so Medicare has no single national rate: payment is (base units + time units) × the locality's anesthesia conversion factor, so the amount varies by locality and case length (Q1 2024 release).
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 00540?
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.
