The California Division of Workers’ Compensation (DWC) has issued an order adjusting the Official Medical Fee Schedule (OMFS) for Physician Services and Non-Physician Practitioner Services. These adjustments, effective for services rendered on or after April 1, 2026, are necessary to conform to changes in the Medicare payment system, specifically adopting the April 1, 2026, quarterly updates to the Medicare National Physician Fee Schedule Relative Value File, updated Practitioner Procedure to Procedure (PTP) Edits, and updated Medically Unlikely Edits.

Healthcare providers in California must ensure their billing and coding practices align with the updated OMFS for services provided on or after April 1, 2026. Failure to comply with the adjusted fee schedule could result in payment denials or disputes. Compliance officers should review the specific changes adopted from the Medicare updates and update internal systems and training accordingly.
