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 64859 in a non-facility setting with national GPCI: (4.14 + 1.32 + 0.89) × $33.4009 ≈ $212.1. The same code in a facility setting pays about $212.1 because facility PE RVU (1.32) replaces office PE RVU.
