Medical narratives are comprehensive reports from treating physicians explaining injuries, treatment, causation, and prognosis in lay terms. These documents bridge medical complexity and jury understanding. Narratives chronologically detail treatment courses and future needs. Causation opinions link specific trauma to diagnosed conditions. Work restrictions and life activity limitations appear. Cost projections for future care support damage calculations. Narratives carry more weight from treating physicians than independent examiners. Preparation involves attorney guidance on legal issues. Cross-examination may challenge opinions exceeding expertise. Well-crafted narratives significantly enhance case values. Insurance adjusters rely heavily on narrative reports for claim evaluation.
