DRG 276 Overview

DRG 276 covers inpatient cases involving implantation or replacement of a cardiac defibrillator with Major Complication or Comorbidity or implantation of a carotid sinus neurostimulator. These procedures are high-cost device-based interventions typically performed by cardiology or electrophysiology teams and often require intensive monitoring and possible management of serious comorbid conditions. The Diagnosis-Related Group matters for Medicare payment because the presence of a Major Complication or Comorbidity increases relative weight and reimbursement, reflecting greater resource use. Accurate coding of principal procedure and secondary diagnoses determines classification into this Diagnosis-Related Group for Medicare inpatient reimbursement.

• Randomized comparative studies of initial device selection and implantation strategies for patients undergoing cardiac defibrillator placement with major comorbid complications: these trials evaluate different device types (single- versus dual-chamber ICDs, transvenous versus subcutaneous systems) and implantation techniques in patients who meet DRG 276 criteria, including those with significant comorbid cardiac or noncardiac MCCs. The patient population typically includes high-risk inpatients admitted for new or replacement defibrillator implantation with complex anatomy, prior infections, or heart failure; outcomes measured include perioperative complications, need for reintervention, and short-term mortality. Results inform hospital clinicians and payers on which implant approaches reduce complicating events and resource use during the index stay, guiding allocation of procedural resources and expected reimbursement drivers.
• Comparative effectiveness and safety studies examining adjunctive therapies and peri-procedural management in complex ICD patients: these observational cohorts or pragmatic trials compare antimicrobial strategies, anticoagulation management, and hemodynamic support protocols used before, during, and immediately after defibrillator implantation in patients with multiple comorbidities. The studies focus on inpatients with MCCs such as advanced heart failure, renal dysfunction, or diabetes who have elevated risk of infection, bleeding, or device-related complications; endpoints include infection rates, bleeding events, length of stay, readmissions, and cost of care. Findings are relevant to providers and payers because optimized peri-procedural protocols can reduce costly complications and shorten hospital stays, directly affecting inpatient reimbursement and quality metrics associated with DRG 276.
• Post-discharge outcomes and utilization research targeting readmissions, long-term device-related complications, and quality-of-life in ICD recipients with major comorbid conditions: these longitudinal studies follow patients after discharge to evaluate rates and causes of readmission, outpatient resource use (e.g., remote monitoring visits, generator replacements), device-related adverse events, and patient-reported outcomes over months to years. The population includes survivors of index hospitalization coded to DRG 276 who often have high baseline morbidity; analyses examine predictors of costly post-acute utilization and functional outcomes. This research helps care managers and payers identify high-risk subgroups for targeted transitional care interventions and informs bundled payment or case-management strategies to reduce downstream expenditures while maintaining patient-centered outcomes.
