Medical treatment utilization schedule (MTUS)

Doctors in California's workers' compensation system are required to provide evidence-based medical treatment. That means they must choose treatments scientifically proven to cure or relieve work-related injuries and illnesses. Those treatments are laid out in the medical treatment utilization schedule (MTUS), which contains a set of guidelines that provide details on which treatments are effective for certain injuries, as well as how often the treatment should be given, the extent of the treatment, and for how long, among other things.

This website provides a link to the guide to MTUS regulations.

Drug Formulary in the California Workers' Compensation System

Assembly Bill 1124 (Statutes 2015, Chapter 525) requires the adoption of an evidence-based workers’ compensation drug formulary by July 1, 2017. The goal is to adopt an evidence-based drug formulary, consistent with California’s Medical Treatment Utilization Schedule (MTUS), to augment the provision of high-quality medical care, maximize health, and promote return to work in a timely fashion, while reducing administrative burden and cost.
