#### Formula

Medicare Physician Fee Schedule (MPFS) Methodology:

Step 1 – Adjust RVUs by Geography (GPCI): Adjusted RVU = (Work RVU × Work GPCI) + (Practice Expense RVU × PE GPCI) + (Malpractice RVU × MP GPCI)

Step 2 – Apply Conversion Factor: Medicare Allowed Amount = Adjusted RVU × Conversion Factor (2024: $32.7442)

Step 3 – Apply Payer & Modifier: Estimated Reimbursement = Medicare Allowed × Payer Rate Multiplier × Modifier Factor × Units

Medicare Split (Traditional Medicare only): Medicare Pays = Allowed × 80% | Patient Coinsurance = Allowed × 20%
