Overview

California's workers' compensation system undergoes regular legislative updates. This article summarizes key changes effective in 2025 that affect disability rating calculations and claims processing.

SAWW Adjustments

The State Average Weekly Wage (SAWW) is updated annually, affecting temporary and permanent disability benefit calculations. The 2025 SAWW adjustment impacts:

  • Maximum temporary disability rates
  • Permanent disability weekly benefit amounts
  • Life pension calculations for high-rated disabilities
  • Current rates are published by the Division of Workers' Compensation (DWC) and incorporated into the Glass Box PD calculator automatically.

    Medical-Legal Fee Schedule Updates

    The Official Medical Fee Schedule (OMFS) receives periodic updates affecting:

  • Evaluation and report fees
  • Diagnostic procedure reimbursement rates
  • Treatment authorization timelines
  • Practitioners should verify current fee schedules through the DWC website for billing purposes.

    Electronic Filing Requirements

    The DWC continues expanding electronic filing mandates. 2025 requirements include:

  • Electronic submission of specific form types
  • Updated portal access procedures
  • Document format specifications
  • Utilization Review Timelines

    Regulations governing utilization review (UR) decisions include updated timeline requirements for:

  • Initial UR decisions
  • Expedited review requests
  • Independent medical review referrals
  • Impact on Disability Calculations

    For permanent disability ratings, the core calculation methodology under Labor Code sections 4660-4664 remains consistent. The Glass Box PD calculator incorporates current adjustment factors and SAWW values as they are published.

    Staying Current

    The DWC publishes updates through its newsline service. Practitioners can subscribe for notifications about regulatory changes, fee schedule updates, and procedural modifications.

    Glass Box tools are updated to reflect current statutory requirements as changes take effect.
