When a work-related injury needs to be reported

Find out when an on-the-job injury needs to be reported to the Department of Industrial Accidents (DIA).

What to know

An employee must be disabled for 5 or full or partial calendar days for the injury or illness to be reported to the Department of Industrial Accidents (DIA).

  • The days don’t need to be consecutive.
  • You have 7 calendar days (except for Sundays and legal holidays) after the injured worker's 5th day of full or partial disability to report the injury to the DIA. You need to file the Form 101 - Employer's First Report of Injury/Fatality via a DIA online account.

If your employee is disabled for less than 5 full or partial calendar days, you can file a “medical only” claim.

  • Medical only claims are reported to your workers’ compensation insurer, not the DIA
  • Contact your workers’ compensation insurer, or agent, for a medical only claim form

The Form 101 - Employer's First Report of Injury/Fatality can only be filed electronically as we no longer accept paper forms.
