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.

HF 450 updates Iowa's workers' compensation rules for permanent partial disability claims. It requires that the extent of permanent impairment be determined solely using the most recent annual update to the American Medical Association's guides, rather than relying on rules adopted by the workers' compensation commissioner. This change directly affects injured workers seeking permanent partial disability benefits and their employers or insurers. The bill removes the requirement for the commissioner to formally adopt the AMA guides by rule, instead mandating the use of the latest available update for all claims filed after the bill's effective date.
