Beside this, how does DRG payment work?A diagnosis-related group (DRG) is a patient classification system that standardizes prospective payment to hospitals and encourages cost containment initiatives. The DRG includes any services performed by an outside provider. Claims for the inpatient stay are submitted and processed for payment only upon discharge.Similarly, is DRG only for inpatient? As of October 2015, the diagnoses that are used to determine the DRG are based on ICD-10 codes.

Also to know is, what are DRG codes? DRG Codes (Diagnosis Related Group) Diagnosis-related group (DRG) is a system to classify hospital cases into one of approximately 500 groups, also referred to as DRGs, expected to have similar hospital resource use. They have been used in the United States since 1983.Are DRG codes used for outpatient?Ambulatory payment classifications (APCs) are a classification system for outpatient services. APCs are similar to DRGs. The initial variable used in the classification process is the diagnosis for DRGs and the procedure for APCs. Only one DRG is assigned per admission, while APCs assign one or more APCs per visit.
