Diagnosis Codes in MS-DRG 205 - Other Respiratory System Diagnoses 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: Other Respiratory System Diagnoses with MCC from October 1, 2024, through September 30, 2025.
MS-DRG: 205
MS-DRG Title: Other Respiratory System Diagnoses with MCC
MCD: 04
Relative Weight: 1.8877 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: 4.50 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.
