Specifications include, but are not limited to:(WSI) reimburses inpatient acute and acute psychiatric services by Diagnosis Related Group (DRG). DRG payment methods involve classifying inpatient stays and then determining a price based on a combination of the classification and the hospital where the services were performed. Classification of the hospital stay is based on the diagnoses describing the patient’s condition, the surgical procedures performed (if any), patient age, and discharge status. The classifications are labeled using codes referred to as DRG codes and the number of codes varies depending on the selected patient classification model. Given the importance of generating fair payment for services provided, the primary objective of a DRG grouper is to categorize hospital stays in a way that most accurately predicts relative hospital resource usage for the care provided to each patient. WSI intends to enter into a contract for a total of 6 years at an estimated cost of $49,800.00.
