The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2022 through 09/30/2023.

MS-DRG	MS-DRG Title	MCD	Relative Weight
573	SKIN GRAFT FOR SKIN ULCER OR CELLULITIS WITH MCC	09	5.8705
574	SKIN GRAFT FOR SKIN ULCER OR CELLULITIS WITH CC	09	3.6046
575	SKIN GRAFT FOR SKIN ULCER OR CELLULITIS WITHOUT CC/MCC	09	2.0496

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
