Submitting Medical Bills Electronically

Providers who have established partnerships with clearinghouses other than Jopari Solutions Inc. or StoneRiver P2P Link may submit e-bills and attachments to State Fund via those existing partnerships.

If you are a first-time provider for State Fund, you must also complete and return an Internal Revenue Services form W-9 or SCIF Form 5159 prior to submitting your e-bill to our clearinghouse. Your bill (paper or electronic) will not be processed until your Taxpayer Identification Number (TIN) is stored within State Fund’s vendor file. Please review our Single Remittance Address Policy regarding your TIN.

E-Billing Regulations

The California Division of Workers’ Compensation (DWC) adopted regulations and standards in 2012, to encourage medical providers to transition to e-billing, improve efficiency of the billing and remittance process, and produce quicker bill payment. Title 8 of the California Code of Regulations covers workers’ compensation medical billing rules and requirements. To assist providers with electronic billing and remittance, the DWC created a guide called “Electronic Medical Billing and Payment Companion Guide 2012.” State Fund will only accept e-bills compliant with Division of Workers Compensation Electronic Medical Billing and Payment Companion Guide or  paper bills served in accordance with 8 CCR §10505(b)(1),(2). State Fund will not accept bills served in any other manner, including, but not limited to facsimile (fax) and e-mail.
