This document provides an overview of the claims data flow and analysis of the as-is state for an external claims system. It includes a diagram showing the flow of claims and encounters from source systems like EMR and ambulance providers through various data stores and analytical tools to downstream customer reports and underwriting. The analysis notes that the 14-year-old claims engine does not support multi-tiered products, has no web capabilities, and upgrades have never been performed, posing vendor risk.
