September 10, 2025 | SIBTF.org — Lawmakers advancing AB 1329 SIBTF reforms have added stricter requirements for injured workers seeking benefits. Under the proposed changes, claimants must now demonstrate that their preexisting disability had a negative impact on their ability to work or perform essential daily activities before qualifying for SIBTF support. This shift is designed to ensure only workers with substantial impairment can access supplemental benefits.
This AB 1329 SIBTF reform also clarifies how prior conditions are evaluated in relation to new workplace injuries. By requiring clear documentation of a disability’s impact before the subsequent injury, lawmakers intend to close loopholes that previously allowed for broader interpretations.
Supporters argue that the AB 1329 SIBTF reforms will make the system more predictable for both injured workers and employers, while critics caution that stricter proof standards could create new hurdles for individuals with complex medical histories.
Medical-Legal Evidence Must Follow Standard Protocols
The bill also establishes new rules for medical-legal evidence. Under AB 1329, evaluations used in SIBTF claims must align with standard workers’ compensation procedures. This requirement aims to eliminate inconsistent medical findings and create a more transparent and reliable review process.
Database of Qualified Medical Evaluators
Another key reform mandates the Division of Workers’ Compensation (DWC) to maintain a centralized database of qualified medical evaluators (QMEs). Legislators believe this change will provide a standardized pool of experts, improve claim accuracy, and reduce the likelihood of disputes between workers, employers, and insurers.
Balancing Integrity and Access
While the reforms focus on accountability and cost control, advocates are closely watching to ensure that changes do not unduly restrict access for injured workers. Striking the right balance between fiscal responsibility and fair access remains at the center of the legislative debate.
