October 15, 2025 | SIBTF.org — The California Division of Workers’ Compensation (DWC) has opened a 15-day public comment period, beginning October 13, 2025, for proposed modifications to its medical-legal regulations. The proposed amendments—published under the state’s formal rulemaking process—aim to refine Qualified Medical Evaluator (QME) procedures, report formatting, and admissibility standards for medical evidence in workers’ compensation cases.
For professionals and stakeholders working with the Subsequent Injuries Benefits Trust Fund (SIBTF), these rule changes are particularly significant. The revisions may directly influence how medical evaluations are standardized, how apportionment is determined, and how causation is documented across complex claims involving both prior and industrial disabilities.
Revised QME Procedures Could Reshape Evidence Standards
The DWC’s proposed changes focus on aligning QME evaluations with clearer documentation and procedural uniformity. Among the key amendments are updates to:
- Section 31.7 and 31.8 regarding QME appointment timelines and replacement protocols;
- Section 35.5 addressing how medical-legal reports are to be formatted and certified;
- Section 41 clarifying electronic service requirements for QME reports.
These reforms are expected to standardize evidence submission, reduce procedural disputes, and streamline the adjudication process. However, some practitioners warn the tighter timelines and new electronic filing mandates may increase administrative burdens—particularly in cases where multiple QMEs or overlapping specialties are needed to assess complex disabilities.
Stakeholder Reactions: Balancing Efficiency and Due Process
Members of both the claimant and defense bars are weighing in. Claimant advocates argue that greater standardization will help prevent inconsistent or incomplete reports that delay benefits. Meanwhile, defense-side experts warn that stricter rules on report formatting and service deadlines could lead to procedural disqualifications that may disadvantage employers or the Fund in heavily contested SIBTF claims.
For SIBTF cases, where precise medical causation and apportionment often decide eligibility, these rule changes could mark a turning point in evidentiary reliability—but also a potential source of litigation over procedural compliance.
Public Comment Window Closes October 28
Stakeholders have until October 28, 2025, to submit feedback on the proposed regulations. The DWC has invited written comments through its official Regulations Unit portal, after which final modifications will be reviewed and published in the California Regulatory Notice Register.
If adopted, the revised medical-legal procedures could take effect as early as January 2026, aligning with broader statutory changes under AB 1329 and other post-reform initiatives reshaping California’s workers’ compensation landscape.
