Abstract
In this study, the authors examine the role of Qualified Medical Evaluators — physicians who have been certified by the California Division of Workers' Compensation to assess injured workers and write reports — in California's Medical-Legal system. The study includes analyses of data from the California Department of Industrial Relations and stakeholder interviews to assess whether the system is sustainable and is meeting its intended purpose.
Background and Purpose
In California, Qualified Medical Evaluators (QMEs)—physicians who have been certified by the California Division of Workers' Compensation to assess and write reports on injured workers—play a critical role in resolving workers' compensation disputes. QMEs evaluate injured workers and write reports to address Medical-Legal (Med-Legal) questions to help resolve the cases. The California Division of Workers' Compensation in the Department of Industrial Relations (DIR) is responsible for the appointment and reappointment of QMEs and for administering the process through which QMEs are assigned to cases.
California DIR contracted with RAND to better understand whether the Med-Legal process is meeting its purpose, whether it is sustainable, and how it could be improved, with a focus on the role of QMEs in the Med-Legal process. Specifically, this study addresses ten high-level research questions:
Is there a mismatch between the supply and demand of QMEs across specialties and geographic areas?
What is the best way to recruit and retain QMEs?
How have recent changes to the QME reimbursement structure impacted overall costs to the workers' compensation system, and should additional changes be considered?
What have been the impacts of structural changes to QME selection, and should additional changes be considered?
How can medical record delivery to QMEs be improved?
How has the quality of Med-Legal reports changed since 2012, and what is the best way to ensure the quality of QME reports?
Are the time frames built into the QME process appropriate and being met?
Are remote telehealth/remote health evaluations being used appropriately, and should any changes regulating their use be considered?
How have litigation practices in the Med-Legal system changed since 2012?
What role have medical management companies (MMCs) played in the Med-Legal process?
Methods
To answer the above research questions, we used both qualitative and quantitative methods. Our qualitative analyses included a review of related policies from other states; interviews with applicants' attorneys, defense, employer, or insurance representatives; MMC representatives; injured workers; and representatives from other states' workers' compensation agencies. We also conducted focus groups with active and former QMEs. Our quantitative analyses included an analysis of data sources maintained by California DIR, including data on QMEs and panel assignments, all-payer workers' compensation claims data, and case status data.
Results
A summary of our review of state policies from 17 other states is shown in Table 1. This review focused on the role that independent medical examinations (IMEs) or similar types of Med-Legal evaluations play in resolving Med-Legal workers' compensation disputes in other states. Overall, we found substantial variation in the role that state workers' compensation agencies play in Med-Legal evaluations in their states. Of the states we reviewed, there were no other states that used the exact same system that California does. However, like California, some state workers' compensation agencies took a more active role in aspects of the Med-Legal process, such as evaluator selection, accreditation, discipline, and quality review. Also like California, some states set evaluation rates according to a state fee schedule and required employers or payers to pay for evaluations. We spoke with two of these states—Colorado and Texas—as part of our qualitative interviews.

We conducted several quantitative analyses to understand how the demand for QME panel evaluations and the supply of QMEs have changed over time and differ by geographic region and specialty. We found that the number of panel assignments has increased steadily over time with the exception of 2013, when evaluations commenting on medical treatment were moved to a separate process, and in 2020–2021 during the coronavirus disease 2019 (COVID-19) public health emergency (Figure 1).
Figure 1.

Panel Assignments and Number of QMEs, by Year
SOURCE: RAND analysis of QME data.
NOTE: N=1,752,557 assigned panels 2012–2024, N=36,922 total QME years active representing 5,034 QMEs. Year refers to the year that the panel was assigned or year during which a QME had an active office for at least part of the year.
To understand whether the supply of QMEs was keeping pace with the demand, we examined the number of QMEs and QME offices (currently, QMEs may have offices in up to ten locations in California) by specialty and geographic location. Overall, we found that the number of offices dropped sharply following the 2013 legislative change limiting QMEs to ten offices. The number of QMEs and offices began to increase gradually from 2013 to 2016, then gradually decreased from 2016 to 2020. Concerns about the decreasing supply of QMEs and increasing demand for panels contributed to a 2021 fee schedule change, designed in part to raise QME reimbursement rates and attract more QMEs to the system. We observed marked increases in the number of QMEs and QME offices following the 2021 fee schedule change, although we noted that these increases were seen primarily in metropolitan counties (Figure 2). We also noted that, even with the overall increase in QMEs, there were still not enough QMEs to field panels in certain subspecialties, such as oncology.

We also conducted several analyses examining the timeliness of the Med-Legal process over time. In general, we noted modest improvements in the time to complete some types of processes, such as time from panel request to panel assignment and time from panel assignment to QME exam date, in recent years. For example, Table 3 shows the time from panel assignment to QME exam date. While there is a decrease in average time to exam date from 2016 to 2023 (in part because the amount of time for which we can observe cases decreases in later years), the time to exam date remains high: 118 days in 2023. The percentage of exam dates occurring within 90 days remains fairly consistent over time, although there is a small decrease in 2020. However, we observe improvements in the percentage of exams occurring in less than 365 days (from 39.0 percent in 2016 to 53.7 percent in 2023). For context, up until 2020, appointments were supposed to be scheduled within 60 to 90 days of panel assignment; otherwise, the party requesting the panel could request a replacement panel or the parties could agree to a timeline extension. In 2020, this time frame was changed to 90 to 120 days under an emergency COVID-19 regulation, and this change was made permanent in 2023.

NOTE: Durations reflect time elapsed between panel assignment and completed QME exam for panels issued from 2016 to 2023. N refers to the number of panels in each year. “No QME Exam from Panel” includes records where no matching QME identifier was found or where a match existed, but the exam occurred outside the panel assignment window (i.e., before the exam or after a subsequent panel assignment).
Figure 3 shows total Med-Legal payments by type of service from 2017 to 2023 to look at overall trends in payments, including following the 2021 fee schedule change that replaced time and complexity payments for QME evaluations with a flat fee, a two-time multiplier for psychiatric and psychologic evaluations, and a $3 per page fee for review of medical records over 200 pages. We found that the 2022–2023 Med-Legal payment average was 57 percent higher than the 2016–2020 average, more than double the 25-percent increase set as a target when the regulations were adopted.

Recommendations and Considerations
Based on our quantitative and qualitative analyses, we provide several high-level recommendations to improve the QME system (Table 4). Along with each high-level recommendation, we suggest specific actions that could be considered and note whether the action, if pursued, would require a legislative change, a regulatory change, or an administrative or other type of change. We also note some areas in which future data collection, analysis, or monitoring may be warranted.
