An Independent Bill Review (IBR) is a process in California’s workers’ compensation system to resolve billing disputes between medical providers and claims administrators. Medical bills often get denied due to exceeding pre-authorized approvals or improper documentation, making it one of the key medical billing challenges providers face.

According to the California Code of Regulations, Title 8, Section 9792.5.12, providers can file an IBR when there is a dispute over the payment amount. The filing fee is $180 per application, reimbursable if the provider wins the dispute. Although the IBR process can effectively overcome medical billing challenges, many medical providers hesitate to file due to the high fee and time-consuming method.

This table shows the breakdown of IBR cases by different medical service types from 2022 to 2024. According to the data provided on the DWC website, 5,704 cases were filed, ranging from durable medical equipment to pharmaceuticals.
