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 45305 in a non-facility setting with national GPCI: (1.12 + 4.62 + 0.2) × $33.4009 ≈ $198.4. The same code in a facility setting pays about $69.14 because facility PE RVU (0.75) replaces office PE RVU.
