The Official Medical Fee Schedule (OMFS) is promulgated by the DWC administrative director under Labor Code section 5307.1 and can be found in sections 9789.10 et seq. of Title 8, California Code of Regulations.

Physician services and non-physician practitioner services

Labor Code section 5307.1 requires the DWC administrative director to adopt an official medical fee schedule for physician services. In California, for purposes of workers' compensation "physician" is defined by Labor Code section 3209.3 subdivision (a) as follows:

"Physician" includes physicians and surgeons holding an M.D. or D.O. degree, psychologists, acupuncturists, optometrists, dentists, podiatrists, and chiropractic practitioners licensed by California state law and within the scope of their practice as defined by California state law.

The physician fee schedule also covers services of non-physician practitioners, such as physical therapists, occupational therapists, nurse practitioners, physician assistants, clinical social workers, clinical nurse specialists, nurse anesthetists, and anesthesiologist assistants.

Rules related to paper medical treatment billing and electronic medical treatment billing are posted on the DWC website.
