Anesthesia Units Calculator

Anesthesia cases (00100-01999) are paid in anesthesia units, not work RVUs. Enter a code, the anesthesia time and the physical status to get base units, time units (one per 15 minutes), modifying units and a Medicare dollar estimate at the 2026 anesthesia conversion factor.

What is included

  • 2026 CMS base units for every anesthesia code, including add-on codes
  • Time units from total minutes or start and end times, with Medicare exact or round-up rounding
  • Physical status P3-P5 modifying units and QK, QX, QY and AD payment modifiers
  • A work RVU calculator for separately billed blocks, lines, TEE and critical care
