Provider Express Billing (PEB) is a free and secure way to submit bills electronically and receive remittances through My L&I.

About PEB

There are three ways to bill electronically:

  1. Direct Entry using a free online form (no need to purchase software or use a clearinghouse).
  2. Upload billing files using your own software.
  3. Submit bills through a Clearinghouse.

What do I need to get started?

  1. You will need an Active L&I Provider Account Number
  2. You will need a My L&I Account.
  3. You will need to request access to your L&I Provider Account Number.
Direct Entry Billing

Direct entry allows you to submit bills using an online billing form and is ideal for providers with no billing software.

  • Online form is a modified version of the CMS-1500 billing form.
  • Provider and claim information are pre-loaded onto the form.
  • Finalized Direct Entry bills can be adjusted or voided online.
  • Can be used standalone or in addition to uploading files or billing through a clearinghouse.
Upload Files

Submit bills and adjustments electronically using your billing software. For this option, your software must be able to create billing files in the HIPAA Compliant 837 format.
