See your local estimate for a sample 90-minute case.
CPT 01402 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 locality conversion factor in the estimate. The PFS row establishes the anesthesia pricing pathway.

Why is there no national PFS amount for 01402?
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. Ask for a locality to see that factor. Anesthesia code: paid via base + time units × a separate anesthesia conversion factor, not the standard PFS RVU formula. Supply a locality (and time_minutes for a specific amount) to compute it.

How often 01402 is billed Copy link
Across Original Medicare in CY2024, 01402 ranked #204 of the 7,879 CPT codes billed to Medicare that year, by patients served or total allowed dollars. It repeats: a patient billed for it in 2024 was billed 1.5 times on average that year.
2024 Medicare fee-for-service national totals. They exclude Medicare Advantage, Medicaid and commercial volume, so real-world use runs higher. This is a calendar-year snapshot from the CMS Physician & Other Practitioners dataset, on a different cycle from the Q1 2024 fee schedule above.

The anesthesia estimate uses the base units, case length, and locality conversion factor identified beside that estimate. The PFS file establishes the pricing pathway. Releases are immutable: historical evidence remains tied to the specified release. Our methodology covers the depth: sourcing, parsing, versioning, and how we cross-check claims before they ship.
