What Is an Agreed Medical Evaluation?

A Subsequent Injuries Benefit Trusts Fund (SIBTF) is a California workers’ compensation program designed to compensate injured workers whose current work injury, combined with prior disabilities, results in total permanent disability. An SIBTF evaluation in California is performed by a qualified SIBTF medical examiner who reviews medical history, assesses combined impairment, and determines eligibility for SIBTF benefits.

Role of the SIBTF Examiner

Evaluation of Prior Disabilities

The SIBTF examiner reviews medical history and prior impairments to determine how pre-existing conditions contribute to overall disability.

Combined Disability Assessment

The examiner evaluates how multiple injuries interact, establishing whether combined impairments meet SIBTF eligibility thresholds.

Apportionment Analysis

A core role of the SIBTF examiner is to distinguish the impact of industrial injuries from prior disabilities for accurate benefit determination.

Permanent Disability Rating

The examiner calculates total permanent disability using California workers’ compensation standards and medical-legal guidelines.

Medical-Legal Reporting

The SIBTF examiner prepares a detailed report that supports SIBTF claims, settlements, and adjudication.

SIBTF medical evaluation services focus on assessing whether an injured worker’s current industrial injury, combined with prior disabilities, qualifies for SIBTF benefits. These evaluations document medical history, impairment levels, and eligibility requirements under California workers’ compensation law.

An SIBTF medical-legal evaluation includes a review of prior medical records, analysis of combined disabilities, apportionment, and a permanent disability assessment. The resulting report provides essential medical evidence used in SIBTF claims and legal proceedings.

An SIBTF medical evaluation is needed for injured workers with documented pre-existing disabilities whose combined impairments may result in total permanent disability. Attorneys and claims professionals rely on these evaluations to support or assess SIBTF workers compensation claims.

SIBTF workers compensation applies only when prior disabilities significantly contribute to total impairment. Unlike standard claims, SIBTF cases require detailed medical-legal evidence proving how multiple conditions combine, making specialized medical evaluations essential.
