Catalina Barajas vs. WELLPOINT HEALTH NETWORK, INC., ZURICH LOS ANGELES

This case involves an applicant who initially sustained a cumulative trauma injury to her upper extremities during a period covered by one insurer. After returning to work with modified duties, she experienced a recurrence and worsening of symptoms, necessitating further treatment and surgery, which the Board now recognizes as a separate cumulative trauma injury. The Workers' Compensation Appeals Board granted reconsideration, reversing the prior finding of a single cumulative trauma injury. The Board held that distinct periods of compensable temporary or permanent disability, as established by medical evidence and treatment, demarcate separate cumulative trauma injuries, aligning with the Rodarte precedent. Consequently, the applicant was found to have sustained two separate cumulative trauma injuries, each attributed to different insurance coverage periods.
