Medical Treatment Utilization Schedule - drug formulary

The Division of Workers’ Compensation has adopted a drug formulary to implement Assembly Bill 1124 (Statutes 2015, Chapter 525). The regulations establish 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.

MTUS Drug Formulary – effective January 1, 2018

Formulary regulations

Healthcare providers treating, evaluating, or performing utilization review in the California workers’ compensation system may access the MTUS (ACOEM) Guidelines and MTUS Drug List at no cost by registering at  

Pharmacy & Therapeutics Committee

The Administrative Director has appointed the P&T committee pursuant to Labor Code section 5307.29.  The formulary regulations (title 8, Cal. Code Regs. §§9792.27.18 – 9792.27.23) set forth a description of the role of the Committee and the qualifications to serve.
