CPT 00794
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.
~$499.44 for a 240-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 8 — set by CMS for this code and the same in every locality. One time unit is 15 minutes, so a 240-minute case adds 16 time units.

Common questions Copy link
Why is there no payment amount for 00794?
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 Q2 2024 release (schedule pfs, effective April 2024). 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. Commercial and cash-pay figures anywhere on this page are arithmetic on the Medicare amount, using commonly cited reimbursement ranges. They're illustrative, and no nationwide claims database stands behind them. Our methodology covers all of this in depth — sourcing, parsing, versioning, and how claims are cross-checked before they ship.
