WAC 296-23A-0400. What is a "diagnosis-related-group" payment system?

A diagnosis-related-group (DRG) system categorizes patients into clinically coherent and homogenous groups with respect to resource use. The department will use an all-patient grouper to perform the diagnostic categorization. To the extent feasible, where DRG relative weights meet acceptable reliability and validity standards, the department will use DRG per case rates for payment of hospital inpatient services.
