Erazo: Unrefuted Medical Reporting Supported Industrial Injury at Lien Trial
Decision: Erazo v. Dedicated Building Servs., No. ADJ21161039 (WCAB Sept. 4, 2026) (panel decision).
A medical report can carry a lien claimant’s injury burden without separate corroborating testimony, but only if the report itself is adequate. In Erazo, three treating reports supplied history, examination findings and reasoned medical causation; the defense offered a denial letter and unsupported attacks on the history. The WCAB upheld the industrial-injury finding while separately ordering the reports admitted into evidence. The September 4, 2026 WCAB panel decision applies the claimant’s burden and substantial-evidence standard to this lien-trial record.
The lien claimants bore the affirmative burden
Because entitlement to treatment-lien payment depended on industrial injury, the lien claimants stood in the worker’s shoes and had to prove injury arising out of and occurring in the course of employment by a preponderance of the evidence.
The physician supplied more than a bare conclusion
The doctor took a history, examined Erazo, described her janitorial work and symptoms, and expressed causation in terms of reasonable medical probability. The WCAB found the reports reasoned and adequate under the substantial-evidence standard.
An unsupported attack did not rebut the reporting
Defense counsel argued that the histories could not be trusted without independent corroboration, but offered no testimony or documentary evidence showing any history was inaccurate. The Board rejected a categorical rule requiring separate corroboration of an otherwise adequate, unrefuted medical history.
Discussing an exhibit does not formally admit it
Although the WCJ discussed the exhibits as admitted in the opinion on decision, that discussion was not itself an admission order. The WCAB granted reconsideration to formally admit the reports, then affirmed the industrial-injury findings.
Key takeaways
- Identify which party bears the burden on industrial injury at lien trial.
- Test whether the medical opinion rests on examination, history, and reasoned probability.
- Support attacks on medical history with record evidence.
- Make sure every relied-upon exhibit is formally admitted.
