Read: Clear Medical Reasoning Carried the Disability Finding

Two medical opinions can produce different disability ratings, but the choice between them turns on their supporting reasoning and the evidence properly before the judge. In Read v. Mobile Home Communities of America, Nos. ADJ19126786 and ADJ19126787 (WCAB Jan. 20, 2026), a panel upheld a 59 percent permanent-disability award and the exclusion of an unlisted supplemental report.

The reports addressed specific and cumulative injury

The worker claimed a September 30, 2016 specific injury and a cumulative injury ending on that date. The judge found industrial injury to both shoulders, both knees and the cervical, thoracic and lumbar spine, but not the ankles. The judge rejected the cumulative-injury claim and awarded 59 percent permanent disability after apportionment.

The employer preferred Dr. Carlblom’s opinion and a 43 percent rating. The judge instead relied on Dr. Emampour’s report. The adopted report explains that choice: Dr. Carlblom’s discussion was difficult to follow, both because of extensive abbreviations and because its reasoning did not clearly explain the claimed cumulative injury. The issue went beyond presentation. The judge could not trace a cogent rationale connecting the findings to that injury theory. Read, adopted judge’s report, PDF pages 5–7.

One considered medical opinion could support the findings

The Board cited Place v. Workmen’s Comp. Appeals Bd. (1970) 3 Cal.3d 372, 378–379, for the principle that one physician’s relevant, considered opinion may constitute substantial evidence despite conflicting medical opinions. The adopted report also considered whether the favored opinion rested on an adequate history and stayed within the physician’s expertise.

Dr. Emampour had reviewed more than three years of medical records, including Dr. Carlblom’s reports, and taken a comprehensive injury history. The judge found that opinion more persuasive and logical. The judge had already applied Dr. Emampour’s apportionment for the cervical, thoracic and lumbar spine in reaching the 59 percent award. The employer bore the burden of establishing the additional apportionment it sought. Read at 2, 7–8.

The proposed supplemental report had a separate admissibility problem

The employer also sought admission of Dr. Emampour’s March 31, 2025 supplemental report, asserting that it might reduce the disability rating from 59 to 55 percent. The judge excluded it. The April 8 pretrial conference statement had not identified the admissibility of that requested report as an issue, no adequate diligence showing explained why it could not have been obtained before discovery closed, and the employer had not objected to the declaration of readiness that led to the conference.

Labor Code section 5502(d)(3) requires identification of trial issues and evidence at the mandatory settlement conference and provides a diligence-based exception for undisclosed or later-obtained evidence. The Board added that even if the employer had not received the report, it could have identified it on the conference statement. When challenging exclusion, the report’s proposed substance should be presented as an offer of proof. Read at 3, 8.

The award survived both challenges

The panel denied reconsideration and adopted the judge’s report. Its analysis required two distinct inquiries: Whether the admitted medical opinion adequately supported the findings, and whether the proposed additional report could enter the record. The possibility of a lower number in excluded material did not resolve the second inquiry.
