"Workers' compensation is a form of insurance providing wage replacement and medical benefits to employees injured in the course of employment in exchange for mandatory relinquishment of the employee's right to sue his or her employer for the tort of negligence." - Wikipedia. This class represents a Workers' Compensation Claim, which identifies a particular work-related injury and the employer, and which accumulates the costs for billable medical services related to treatment of the injury. Claims for reimbursement must cite the case identifier in order to be processed. Note that the FHIM treats Workers Compensation Claims as a type of Patient Case Management, in that they share a certain amount of active oversight by a case manager.
