Review and evaluate a variety of evidentiary documents (e.g., narrative medical reports commenting upon the relationships of the disability to the implicated employment factors, history of claimants disability and health history, specifics of employment felt to be the cause of injury, job descriptions, workplace exposures, comments on the veracity of the claimants statements, employment records, letters or certificates of medical necessity, etc.) from a variety of sources submitted with or subsequent to the initial claim. Prepare correspondence and maintain working relationships with claimants, witnesses, employers, physicians, medical providers, investigators, representatives, attorneys, and other sources to obtain missing or supplemental medical and employment documents, to clarify information, and to secure additional factual and medical information needed to adjudicate the claim.
