Procedure Codes in MS-DRG 001 - Heart Transplant Or Implant Of Heart Assist System 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 procedure codes included in MS-DRG V43.0: Heart Transplant or Implant of Heart Assist System with MCC from October 1, 2025, through September 30, 2026.
