CPT 01230
Priced using anesthesia methodology — base units plus time units, not the standard RVU formula.
No national payment amount
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.
~$295.12 for a 120-minute example case in Dallas, TX
Where this example comes from
(base_units + time_units) × anesthesia_cf time_units = time_minutes / 15. The anesthesia conversion factor is CMS's published locality-adjusted value.
Source
Anesthesia has no single national rate — payment is (base units + time units) × the locality's anesthesia conversion factor, so the amount above is an example computed with Dallas, TX rates, before sequestration. Enter your ZIP and your own case length for your locality's number.
Base units 6 — set by CMS for this code and the same in every locality. One time unit is 15 minutes, so a 120-minute case adds 8 time units.

Why isn't there a national PFS amount?
- Status 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.

Common questions Copy link
Why is there no payment amount for 01230?
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. The blank is deliberate: the amount is either unknown or paid under another provision, so reading it as $0 would be wrong.
When does this rate change?
CMS publishes a fee schedule release every quarter (January, April, July, October), and each is versioned here. See what changed each release, or get an email when a new release moves rates.

This is computed from CMS's Medicare Physician Fee Schedule Q1 2023 release (schedule pfs, effective January 2023). National amounts apply a GPCI of 1.000 and leave sequestration off. The status indicator decides payability, never the RVU values, so a blank RVU stays blank. Releases are immutable: a rate retrieved for a past quarter always reflects that release. Our methodology covers the depth: sourcing, parsing, versioning, and how we cross-check claims before they ship.
