EOR Non-compliant - Incomplete

When an EOR received from a claims administrator lacks information required by Labor Code 4603 or Appendix B of the DWC Billing and Payment Guide, we strongly recommend that you file an Audit Complaint. Doing so could improve California workers’ comp billing for the entire community.

Frequently Asked Questions

Q: What’s an Audit Complaint?

A: Audit Complaints are designed to alert the DWC to non-compliant behavior on the part of a claims administrator. Using your Audit Complaints, the DWC can intervene and correct a claims administrator’s improper bill processes.

Q: Will a claims administrator know if I file an Audit Complaint against them?

A: Not if you don’t want them to. The DWC allows you to file Audit Complaints confidentially, so reporting improper behavior poses no risk to your relationship with the claims administrator.

Q: Will filing an audit complaint guarantee correct reimbursement?

A: Not necessarily – the DWC cannot promise that every complaint will result in an audit or investigation. The DWC does intervene when appropriate, though, and the data collected from an Audit Complaint can ultimately lead to improvements across the entire California workers’ comp community.

Regulations and Rules

Labor Code 4603.3. (a) Upon payment, adjustment, or denial of a complete or incomplete itemization of medical services, an employer shall provide an explanation of review in the manner prescribed by the administrative director.

Per the
Division of Workers’ Comp Billing and Payment Guide, an “Explanation of Review” (EOR) means the explanation of payment or the denial of the payment as defined in Appendix B.

Per Appendix B: This Appendix provides Explanation of Review (EOR) instructions for both paper and electronic EORs. The Explanation of Review is required to be used for both the original bill review determination and the final written determination that is issued by the claims administrator after processing a request for second review. When a bill is being paid in full or in part, the EOR also serves as a remittance advice.
