Summary & Overview
Spinal Fusion Except Cervical with Spinal Curvature, Malignancy, Infection or Extensive Fusions with CC: Inpatient Reimbursement Overview
DRG 457 addresses noncervical spinal fusion cases complicated by spinal curvature, malignancy, infection, or extensive fusion constructs with a Complication or Comorbidity, and it represents higher-complexity inpatient spine surgery. Proper assignment is important for inpatient reimbursement because it aligns payment with the increased resources required for complex surgical care and comorbidity management.
DRG 457 Overview
DRG 457 covers inpatient spinal fusion procedures excluding cervical levels when performed for patients with spinal curvature, malignancy, infection, or extensive fusion constructs accompanied by a Complication or Comorbidity. This Diagnosis-Related Group captures complex thoracic, thoracolumbar, and lumbar fusion cases with higher resource use driven by surgical complexity, comorbid conditions, and perioperative management. It matters for Medicare payment because classification into this group influences hospital reimbursement rates and reflects elevated inpatient resource intensity. Accurate clinical coding of diagnoses and procedures determines assignment to this Diagnosis-Related Group and the associated payment.
