File your claim in Iowa
- Time limit
- 2 years
- Counted from
The date you knew or should have known the injury was work-related; or, if weekly benefits were paid, 3 years from the last payment of weekly benefits
- What to file
Original Notice and Petition for arbitration, filed with the Workers' Compensation Division through its electronic filing system (WCES)
Source: Form 100
- Who files it
You report the injury to your employer. Your employer (or its insurance carrier) files the First Report of Injury with the Workers' Compensation Division. You file an Original Notice and Petition with the Division only if there is a dispute that cannot be resolved.
- What your employer must do
Your employer must file a First Report of Injury with the Workers' Compensation Division within 4 days after notice or knowledge of an injury that causes more than 3 days of lost work, permanent injury or death.
- When the insurer decides
Weekly payments are due starting on the 11th day after the injury. Late payments carry interest, and unreasonable delay or denial can lead to penalty benefits. Once benefits start, they can stop only when you return to work or after 30 days' written notice explaining why and telling you that you can file a claim with the Commissioner.
- Illness that develops over time
The 2-year period runs from the date you knew or should have known that the condition was work-related.
If no weekly disability benefits have been paid, you must file a petition with the Workers' Compensation Division within 2 years from the date of injury, or you may lose your benefits. If weekly benefits have been paid, you have 3 years from the last weekly payment to file. Payment of medical expenses or mileage does not extend the deadline.
