Sacramento, California – California’s workers’ compensation medical payment system is getting one of those quiet updates that rarely makes noise outside billing departments, but still matters every time an injured worker sees a doctor, therapist, physician assistant or other provider.
The Division of Workers’ Compensation has posted an Administrative Director order adjusting the Official Medical Fee Schedule for Physician Services and Non-Physician Practitioner Services. The update brings California’s workers’ compensation fee schedule back in line with selected Medicare payment changes, as required under Labor Code section 5307.1.
The changes apply to services rendered on or after July 1, 2026. That date is the key detail for claims administrators, billers, coders, providers and insurers. Services before July 1 remain under the earlier rules. Services on or after that date must reflect the new third-quarter files.
This is not a dramatic rewrite of the system. It is more like maintenance under the hood. The order adopts CMS’ Medicare National Physician Fee Schedule Relative Value File quarterly update, known as RVU26C, along with updated Practitioner Procedure-to-Procedure edits and updated Medically Unlikely Edits. In plain language, that means California is refreshing the values and coding controls used to calculate or review payments for thousands of medical services.
The Official Medical Fee Schedule, or OMFS, is the backbone of medical reimbursement in California workers’ compensation. It helps determine what doctors, therapists, nurse practitioners, physician assistants and other professionals are paid when they treat people hurt on the job. For many services, payments are tied to Medicare’s resource-based system, then adjusted through California’s own workers’ compensation rules.
That matters because workers’ comp care is not always simple. Providers often deal with reports, utilization review, authorizations, disputes and return-to-work documentation that do not exist in the same way in ordinary health care. Earlier in 2026, DWC adopted broader physician fee schedule changes effective March 1, including updates to relative value units, coding, conversion factors, National Correct Coding Initiative edits, anesthesia conversion factors and telehealth rules.
The July update is narrower, but still practical. Procedure-to-Procedure edits help prevent improper unbundling, when services that should be billed together are split apart. Medically Unlikely Edits set limits on how many units of a service would typically be reasonable for one patient on one day.
For injured workers, the effect is mostly indirect. The goal is not a new benefit or a new program. It is a cleaner payment system, fewer billing disputes and a better chance that providers remain willing to treat workers’ compensation patients. For everyone processing claims after July 1, the message is simple: load the new files, check the edits and do not treat this routine update as optional.
