Case Management, in the context of a health insurer or health plan, is defined as: "A method of managing the provision of health care to members with high-cost medical conditions. The goal is to coordinate the care so as to both improve continuity and quality of care and lower costs." This class contains properties needed to identify a Case for the purposes of managing costs associated with that Case. Therefore claims for Billable Services will cite the Case Id contained herein. Note that a Workers' Compensation Claim is not a single claim as the name implies, but a Case, and is modeled as a sub-type of Case Management.
