Help us provide care for injured workers, and pay you promptly.

Prevent payment delays

To speed up your payment, bill us online using Provider Express Billing.

To avoid denials, payment reductions, or having your payment sent to the wrong place:

  • Don't Fax Bills, we do not accept faxed bills, and they will not be processed.
  • Use procedure codes that match the level or type of service billed.
  • Provide documentation, and reports at the right time, in the correct format.
  • Notify us if your address or business status changes with the Provider Accounts Change Form (F245-365-000).

Make sure you fax reports correctly:

  • Send reports, and chart notes separately from bills.
  • Put our claim number in the top right corner of every page of each document.
  • Use 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 us so it goes directly to the claim file.
