A bill for an act relating to standards for determination of loss or permanent impairment for purposes of permanent partial disability under workers’ compensation and including applicability provisions.

This Iowa bill (SF 454) updates how workers' compensation claims for permanent partial disability are calculated. It requires using the most recent annual update to the American Medical Association's impairment guides (currently the 2024 update to the sixth edition) instead of the commissioner's rule-based adoption of older versions. The change directly affects workers injured on the job who seek permanent partial disability benefits, ensuring their impairment percentage is determined solely by the latest medical guidelines. It also prohibits using lay testimony or agency expertise in specific disability evaluations under these guidelines. The policy applies to all claims filed after the bill's effective date.
