Diagnosis Codes in MS-DRG 545 - Connective Tissue Disorders With MCC
The Medicare Severity Diagnosis-Related Group (MS-DRG) is a patient classification system used to categorize hospital cases based on clinical similarity and expected resource use. MS-DRGs organize all possible principal diagnoses into mutually exclusive groups known as Major Diagnostic Categories (MDCs), which help determine reimbursement under the Medicare Inpatient Prospective Payment System.
This section lists the diagnosis codes included in MS-DRG V42.0: Connective Tissue Disorders with MCC from October 1, 2024, through September 30, 2025.
MS-DRG: 545
MS-DRG Title: Connective Tissue Disorders with MCC
MCD: 08
Relative Weight: 2.5267 Relative Weight
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.
Arithmetic LOS: 5.80 Arithmetic Length of Stay
The average length of stay (ALOS) reflects the average number of days a patient spends in a hospital for each admission.
