Combine multiple impairment ratings instantly using the AMA combined values formula — built for occupational medicine physicians. Stop doing the combined values math in your head.

The combined result updates in real time, displayed as a rounded whole number with the exact decimal available for reference. WHY PHYSICIANS USE IT • No login. No subscription. No ads. • Designed for clinical workflow — get in, get your answer, get out. • Clean interface built for use during evaluations and dictation. • Accurate combined values per AMA conventions.
