Procedure Codes in MS-DRG 259 - Cardiac Pacemaker Device Replacement Without 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 procedure codes included in MS-DRG V43.0: Cardiac Pacemaker Device Replacement without MCC from October 1, 2025, through September 30, 2026.

MS-DRG: 259

MS-DRG Title: Cardiac Pacemaker Device Replacement without MCC

MCD: 05

Relative Weight: 2.0221 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.

Geometric LOS: 2.02 Geometric Length of Stay
The geometric mean length of stay (GMLOS) is used by Medicare to calculate the reimbursement for patients whose medical treatment takes a much longer or shorter time than average.

Arithmetic LOS: 2.40 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.
