Denial Incorrect - Duplicate Bill

Last update
July 31, 2018

When an EOR incorrectly denies an Original Bill as duplicate billing, 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.
