Summary & Overview
Coronary Bypass with PTCA with MCC: Inpatient Reimbursement Overview
DRG 231 describes coronary artery bypass grafting combined with percutaneous transluminal coronary angioplasty when a Major Complication or Comorbidity is present, encompassing high-complexity cardiac revascularization. Proper assignment influences inpatient reimbursement because the additional complication or comorbidity increases expected resource use and payment under Medicare.
DRG 231 Overview
DRG 231 covers inpatient hospitalizations for coronary artery bypass grafting combined with percutaneous transluminal coronary angioplasty when a Major Complication or Comorbidity is present. This Diagnosis-Related Group applies to complex revascularization cases where both surgical and percutaneous procedures are performed and significant additional diagnoses increase resource use. It matters for Medicare inpatient payment because the presence of a Major Complication or Comorbidity raises the relative weight and reimbursement, reflecting higher expected costs of care. Accurate clinical coding and documentation determine assignment to this Diagnosis-Related Group and therefore materially affect hospital payment.
