What Happens If Your Treatment Is Denied in California
California's workers' compensation system includes a dispute process most other states don't have in this form: Independent Medical Review (IMR). If your claims administrator's utilization review denies, delays, or modifies your treating physician's request for medical care because it's deemed "not medically necessary," you have the right to request an IMR.
How IMR Works
One or more anonymous, board-certified physicians in the relevant specialty review your medical records — without examining you in person — and issue a binding decision. This is different from a Qualified Medical Evaluator (QME), a state-certified doctor who conducts an in-person exam to help determine your benefit level and whether your injury is work-related.
Knowing which process applies to your situation matters: IMR resolves treatment disputes, while a QME evaluation addresses the extent of your disability and benefits. You can request an IMR through the California Division of Workers' Compensation.
