How to Request Authorization from the California Division of Workers' Compensation

What a Request for Authorization (RFA) Is and When It Is Required

In California workers' compensation, a Request for Authorization (RFA) is the formal process by which a medical provider (or you, the injured worker) asks the Division of Workers' Compensation (DWC) for permission to deliver or continue a specific treatment. Health care providers must obtain preauthorization for many services, including surgeries, certain therapies, and expensive durable medical equipment. Failing to get required approval before care is delivered can result in claims being denied or delayed payment. In the following sections, we explain how the RFA process works in practice, how you can track its status, common reasons for denial, and how to appeal if needed.

Key Facts at a Glance

The RFA Process in Practice

The RFA process begins with the correct form, typically the DWC Form RFA (Request for Authorization), completed with accurate patient and provider information, a clear diagnosis, and a detailed description of the requested treatment. The request must explain why the treatment is medically necessary and how it relates to the accepted compensable condition. Submit via the methods accepted by DWC, which often include the HealthCare Compliance System (HCS) for electronic filing or mail for paper submissions. Once received, the DWC reviews the request against medical necessity guidelines, evidence standards, and the injured worker's claim status. A timely, complete submission reduces the risk of delays or denials due to missing information or lack of clinical justification.

How to Track Your RFA Status

After submission, you can monitor the RFA status through the DWC's online services or by contacting the DWC helpdesk. Providers using HCS can check real-time adjudication outcomes within the system. Workers and providers should note the date of submission and follow up if no decision arrives within the typical 21-day window. Keeping copies of all correspondence, including confirmation numbers and email receipts, is essential if you need to dispute a denial or escalation. Prompt tracking helps ensure that incomplete requests are supplemented quickly, which improves overall approval odds.

Common Reasons for RFA Denial and Immediate Steps

Denials usually occur because the DWC determines the treatment is not medically necessary, not related to the compensable injury, or not preauthorized. Other frequent issues include missing documentation, unclear treatment plans, or services not covered without prior approval. If your RFA is denied, first review the denial letter for specific reasons and required supplements. You may request additional information, clarify medical necessity, or correct clerical errors. For time-sensitive care, communicate immediately with the DWC and the provider to discuss interim options or urgent review.

How to Appeal an RFA Decision

To challenge an RFA denial, you typically must file Form R-44 (Request for Conference) to initiate a conference with a deputy compensation insurance commissioner, or proceed directly to an Application for Adjudication if you prefer a formal hearing. Gather supporting evidence such as medical records, physician statements, and treatment plans that demonstrate necessity and relation to the work injury. Deadlines apply, so respond promptly to any DWC notices. Successful appeals often hinge on clear medical justification, complete documentation, and adherence to procedural rules. Legal or advocacy support can help navigate complex cases and ensure your rights are protected.

Best Practices for a Smooth RFA Experience

• Submit complete information upfront, including diagnosis, procedure codes, and medical necessity narrative.
• Use electronic filing when available to speed up processing and obtain real-time status updates.
• Confirm receipt of your RFA and keep records of all communications.
• Monitor the 21-day decision window and follow up if no action is received.
• If denied, review the reasons carefully, supplement with missing evidence, and consider timely appeal options.
