A bill for an act relating to injuries subject to workers’ compensation and including retroactive applicability provisions.

HF 421 extends the deadline for filing workers' compensation claims when an employee cannot get an accurate diagnosis due to delays from an employer-chosen health provider. It allows the filing period to be extended until diagnosis is possible, but only if the delay was solely caused by the provider and the employee made a diligent effort to get care. The bill also changes the definition of "date of injury" to when the employee knew or should have known the injury was work-related and serious enough to permanently affect their job. This applies retroactively to injuries occurring on or after August 1, 2022, directly affecting workers seeking compensation for delayed-diagnosed injuries.
