The claimant was involved in two accidents and sustained a heart attack months after the second accident. A treatment plan for assistive devices was denied by the insurer with the assistance of a GP IE report. The insurer objected to the inclusion of documents not disclosed 10 days before the service and filing of written submissions, pursuant to LAT Rule 9. Adjudicator Theoharis ruled that since the insurer’s response submissions afforded it 10 days, the materials were properly disclosed. On the merits, Adjudicator Theoharis determined that the treatment plan for assistive devices was reasonable and necessary and that the treatment undertaken by the claimant had to be cognizant of the heart condition suffered afterwards.
