Washington F242-243-000: Notice of Occupational Disease

Washington medical providers use this notice after diagnosing a worker with an occupational disease or infection when no claim form is completed at that visit. The provider certifies the diagnosis, tells the worker of the right to file a workers' compensation claim, and explains that a claim must be filed within two years from the date the form is signed and a copy is given to the worker.

Who completes it

The examining provider completes the medical section (provisional diagnosis with ICD code, date of first treatment, provider number and type of exposure), and a licensed physician must sign. The worker helps complete the worker, employer and exposure section.

Submitting and payment

How to submit it
Give a copy to the worker and mail the original to L&I's Claims Section. If the worker wants to file now, complete the Report of Accident instead and follow its mailing instructions.
Who pays
L&I's Reports and Forms payment policy does not list a billing code for this notice, while the Report of Accident, when completed instead, is billed with local code 1040M.

Good to know

  • Use it only when the provider and worker do not complete a Report of Accident; if the worker asks to file, complete the accident report with them instead.
  • Describe the exposure that appears to have caused the disease, such as noise, specific chemicals, toxic substances, job activities, or a bacterial or viral infection.
  • It is a flat PDF with no fillable fields, marked original for L&I and copy for the worker, and it asks for current and previous employers with dates.

The list was last checked in October 2026. Forms and their requirements change without notice, so check the official page for the current version before you complete one.

Frequently asked questions

Why does the Washington Notice of Occupational Disease matter for the worker?

It documents that a provider diagnosed an occupational disease or infection and told the worker of the right to file. The worker must then file a claim within two years from the date the form is signed and a copy is provided, so handing the worker a copy is part of the process.

Who can sign the occupational disease notice?

The form says a licensed physician must sign. The signer certifies having examined the worker, determined that the disease or infection was caused by the occupation, and advised the worker of the right to file a claim and of the two-year filing limit.
