Billing Self-Insured Employers

When you treat an injured worker insured by their employer rather than by the State Fund, submit bills directly to the employer or their claims representative.

How to determine if an employer is self-insured:


Self-insured employers must authorize treatment and pay bills according to the same Medical Aid Rules and Fee Schedules followed by L&I.

If you don't agree with a payment received from a self-insurer, you must follow WAC 296-20-125(9), and inquire about it within ninety days of payment to be considered.


Need L&I's Self-Insurance Section's assistance? All disputes must be received in writing.

  • For bill underpayment disputes, only:
  • For all other disputed issues:
    • Include the department's claim number on your fax cover sheet, and fax all information to 360-902-6900, or
    • Contact L&I's Self-Insurance receptionist at 360-902-6901.
