Workers Compensation Appeals

Developed as part of California's efforts to reform and control medical care and indemnity benefit costs in the workers’ compensation system, our independent medical review (IMR) solution resolves disputes about the medical treatment of injured employees.  Individual cases are routed to an independent healthcare professional who is screened to ensure he or she has no conflict of interest with the parties in the case.  With the introduction of IMR, disputes are resolved in 2 weeks on average - down from nearly 12 months under the cumbersome court system it replaced.
