Here is how the Medicare Physician Fee Schedule arrives at the CPT 01420 amount above, and what it does and doesn't cover.
Anesthesia codes carry no RVUs. Medicare adds the code's base units to time units (one per 15 minutes of anesthesia time) and multiplies the total by the locality's anesthesia conversion factor — the $20.76 per-unit figure above.
Each Medicare locality has its own anesthesia conversion factor, geographically adjusted like the rest of the Physician Fee Schedule. There is no facility vs. non-facility split.
Commercial payers set their own negotiated rates, and routinely pay above or below the Medicare amount for the same code. See how UHC, Aetna, Cigna and BCBS actually price 01420.
