Upload files using your billing software

Submit bills and adjustments electronically using your HIPAA compliant billing software by uploading files directly to L&I. Note that L&I does not provide software for this option.

Provider Express Billing (PEB) supports the HIPAA Compliant formats documented in the companion guides listed below.

  • EDI X12 837 Professional
  • EDI X12 837 Institutional
  • 835 Remittance Advice

Follow these 4 simple steps:

  • Make sure that you have billing software that can create a file in the HIPAA compliant 837 formats. Because L&I does not provide this software, you may need to contact your software vendor to see if your system can create the required file format.
  • Contact the Electronic Billing Unit at 360-902-6511 to have your account updated to test with the Department.
  • Create an account in My Secure L&I (powered by SecureAccess Washington).
  • Submit electronic test file(s) until approved to submit production files.
