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
545	CONNECTIVE TISSUE DISORDERS WITH MCC	08	2.5086
546	CONNECTIVE TISSUE DISORDERS WITH CC	08	1.2056
547	CONNECTIVE TISSUE DISORDERS WITHOUT CC/MCC	08	0.9148
