Why it Matters
Simplify Case Prep and Maximize Client Results with Fast, Thorough Permanent Disability (PD) Rating Calculation
Gemini Legal knows PD rating can make or break a workers’ compensation case so we made it easy to calculate complete, accurate impairment rating and payments.
Our in-house developed calculator is robust and reflects the latest California Labor Codes and American Medical Association (AMA) guidelines. As a result, you can complete the complex math needed to calculate whole person impairment (WPI) and run dynamic total compensation calculations without a clunky user interface or loss of past calculations.

FREE TOOL
Add impairments across body parts under Kite/Vigil
Most calculators only combine multiple impairments, which pushes the final rating down. Ours also adds them where Kite and Vigil support it — the difference between a rating that reflects your client's actual disability and one that quietly understates it.
