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 64590 in a non-facility setting with national GPCI: (4.97 + 7.12 + 0.73) × $33.4009 ≈ $428.2. The same code in a facility setting pays about $266.87 because facility PE RVU (2.29) replaces office PE RVU.
