WCCombine

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.

Impairment Combiner is a fast, distraction-free tool for occupational medicine physicians, IME evaluators, and workers' compensation professionals who need to combine multiple whole person impairment (WPI) ratings using the AMA Guides combined values formula.

HOW IT WORKS

Enter each impairment rating — the app applies the combined values formula instantly:

Combined = 1 − (1 − A) × (1 − B) × (1 − C) …

Add as many ratings as you need. Remove any by tapping. The combined result updates in real time, displayed as a rounded whole number with the exact decimal available for reference.
