Is the workers employer self-Insured?
Use the Find a Self-Insured Employer look up tool to determine if an employer is self-insured and look up their third-party administrator contact information. If the employer is self-insured, complete the Provider's Initial Report and submit it to the self-insured employers claim contact.
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 90 days of payment to be considered.
You can bill the self-insured employer interest on the balance due when payment isn't made within 60 days of receipt of a proper bill. Use the L&I local code 1159M to bill interest.
Calculate the interest due by using the Self-Insurance Medical Bill Interest Calculator (SIMBIC).
If the employer is not self-insured, see the Medical Providers page under Claims.

For bill underpayment disputes only complete and submit the Self-Insurance Medical Provider Billing Dispute form (F207-207-000), or call L&I's Self-Insurance Section at 360-902-6938. 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, if you need help identifying the department claim number.
The department won’t require self-insured employers to develop or change existing automated payment systems; however, the department will require that self-insured employers process proper billings.
If an approved provider submits a complete billing to a self-insured employer for proper and necessary medical services with the appropriate ICD coding, the self-insured employer should respond to the billing.
