Instead of assigning a single procedure code and fee, anesthesia services are billed based on a formula that combines multiple components. The most important part of this formula is **time**, and that’s exactly what this tool helps you calculate. How Anesthesia Billing Works Unlike surgical procedures that are billed using fixed procedure codes, anesthesia billing is calculated using: Total Anesthesia Units = Base Units + Time Units + Modifying Units** This calculator focuses on **Time Units**, which are determined by how long the anesthesia service lasts. Time-Based Calculation (15-Minute Rule) Anesthesia time is counted from the moment anesthesia starts until it ends. Time is then converted into billable units. Every **15 minutes = 1 time unit** Partial units may be rounded depending on payer...
