CMS Pub. 100-04 Ch. 12 50: anesthesia payment = (base + time + modifying units) x the anesthesia CF; time unit = 15 min. ASA RVG base units are entered, not shipped. Medical-direction modifiers AA/QZ pay 100%, QK/QY/QX 50%, AD a flat 3 base units. Read the source ↗
Worked example: (5 base + 4 time + 1 modifying) = 10 units x $22 = $220; medically directed (QK 50%) = $110.
