Roberto Barrero vs. Knudsen Dairy Corporation, Fireman's Fund Insurance Company
This case involves a dispute over the compensability of cardiovascular injury and Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) following a 1975 industrial injury. The Workers' Compensation Appeals Board (WCAB) affirmed the findings that the applicant failed to prove CIDP was work-related but sustained his burden that cardiovascular treatment is a compensable consequence of the industrial injury. The WCAB clarified that enforcing medical treatment for the cardiovascular condition, which arose during authorized back surgery, falls under its continuing jurisdiction, not a prohibited amendment of the original award more than five years post-injury. Medical opinions regarding causation were found to constitute substantial evidence, resolving conflicting expert testimony.
