Jeanette Chamorro — ADJ10793276, ADJ10870183

Applicant Jeanette Chamorro, a cheese packer, filed two claims: a cumulative trauma injury (ADJ10793276) to her upper extremities/hands and a second cumulative trauma injury (ADJ10870183) to her lumbar spine, right shoulder, wrists, cervical spine, and hands. The WCJ found 41% permanent total disability with all PD attributed solely to the second CT injury, plus TD and future medical care. Both Stonington and Zurich sought reconsideration, with Stonington challenging the attribution of all PD to the second injury and Zurich seeking an EDD credit. The Board, after granting reconsideration, rescinded the June 1, 2020 Joint Findings, Award and Order and returned the matter to the trial level because the medical record was not adequately developed on the threshold issue of whether there were one or two cumulative trauma injuries and on Benson apportionment. The Board also criticized the earlier piecemeal August 19, 2019 decision for creating confusion regarding dates of injury and failing to address date of knowledge and first date of disability under section 5412.
