Submitting Bills and Reports

You can help L&I provide care for injured workers and pay you promptly.

Prevent payment delays

To speed up your payment, bill L&I online using Provider Express Billing.
To avoid having L&I deny or reduce payment or send your payment to the wrong place, make sure that you:

  • Don’t Fax Bills, L&I does not accept any bills that are faxed, they will not be processed
  • Use a procedure code that matches the level or type of service billed.
  • Provide documentation and reports at the right time in the right format.
  • Notify us when your address or business status changes, by using the Provider Accounts Change Form.

In addition, make sure that you fax reports correctly:

  • Send reports and chart notes separately from bills.
  • Put the L&I claim number in the top right corner of every page of each document.
  • Use only plain, white paper and do not highlight, to assure clear imaging.
  • Do not use address stamps or labels that are too large for a form.
  • Make sure documentation is legible.
  • Fax your chart documents to L&I so that it goes directly to the claim file.
