Submitting Bills and Reports

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

• Prevent payment delays
• Faxing reports and chart notes
• Where to mail paper documents
• For desk references

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:

• 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.
