Independent Medical Review in California
Workers' Compensation

You have 30 days from the date of the Utilization Review denial letter. This deadline is absolute. There are no extensions and no exceptions. Missing it by even one day permanently eliminates your right to challenge that specific denial through IMR. If you're close to or past 20 days from your denial letter, call us immediately.

IMR decisions are based entirely on the documentation submitted, not on a physical examination, not on your treating physician's judgment, and not on your stated symptoms. If the medical records don't clearly demonstrate that the treatment meets specific MTUS criteria, the denial is upheld. Most unrepresented workers submit the same documentation that was already denied, without the MTUS-aligned arguments needed to change the outcome.

No. The IMR reviewer never examines you in person. They never speak with your treating physician. You are not told who they are, what their qualifications are, or whether they have any disciplinary history. They review only the medical records and documentation submitted to them. Their decision is made entirely on paperwork and is binding.

This is significant. If the insurance carrier failed to issue the UR decision within the statutory 5-business-day timeframe, or violated required procedural steps, the denial may be invalid on its face. These situations do not route through IMR. They go directly to a WCAB hearing where the procedural violation can result in treatment authorization. Identifying these violations requires someone who reviews the exact timeline and procedures of every denial. This is standard practice in Thomas DeBenedetto's office.

Technically yes. The form exists. But the form alone doesn't determine the outcome. The documentation you submit does. Without MTUS-aligned medical arguments and properly assembled supporting records, the IMR reviewer has no basis to overturn the denial. Most unrepresented workers who file do not win. The 90% uphold rate reflects, in large part, the quality of submissions by workers without legal representation.

Nothing upfront. Workers' compensation cases are handled on a contingency basis. Fees are tied to recovery, approved through the California state system. You take zero financial risk by calling today. Most workers dealing with IMR denials have had their treatment blocked and income interrupted. The ability to hire experienced representation should not depend on your current financial situation. It does not.

No. Four pathways remain. First, a new Request for Authorization can be submitted if your condition has worsened or new objective findings support the treatment more clearly. Second, if the IMR determination contained factual errors or plainly misapplied MTUS guidelines, a WCAB petition under Labor Code 4610.6 may be available. Third, if treatment delay is creating urgent medical harm, an expedited WCAB hearing can force faster resolution. Fourth, if the insurance company is also disputing causation or disability. These are issues IMR cannot resolve. A QME evaluation runs separately and can reopen treatment questions. An IMR uphold is not a final verdict. It is the next starting point.

IMR only handles medical necessity disputes: specifically, whether a treatment your doctor already recommended is medically justified under MTUS guidelines. It does not resolve whether your injury is work-related, your permanent disability rating, disputes about your treating physician, or whether a new injury occurred at work. If the insurance company is contesting the injury itself rather than the specific treatment, you are in a different dispute handled through the WCAB and not through IMR. Many workers file IMR on the wrong dispute and lose time on the correct one. Knowing which fight to pick from the start is where legal experience matters most.
