How the payment is calculated
Total RVU is work plus practice expense plus malpractice, each adjusted by its GPCI factor, then multiplied by the conversion factor. For 33521 in a non-facility setting with national GPCI: (12.28 + 2.45 + 3.03) × $33.4009 ≈ $593.2. The same code in a facility setting pays about $593.2 because facility PE RVU (2.45) replaces office PE RVU.
