Summary & Overview
Combined Anterior and Posterior Cervical Spinal Fusion with MCC: Inpatient Reimbursement Overview
DRG 429 addresses combined anterior and posterior cervical spinal fusion performed with a Major Complication or Comorbidity and defines a high-acuity surgical inpatient category. It matters for inpatient reimbursement because the fusion approach combined with the presence of a Major Complication or Comorbidity increases the Diagnosis-Related Group weight and associated Medicare payment compared with less complex cervical fusion groupings.
DRG 429 Overview
DRG 429 covers combined anterior and posterior cervical spinal fusion procedures performed during the same inpatient stay when a Major Complication or Comorbidity is present. This Diagnosis-Related Group reflects high-resource surgical care for complex cervical spine instability or deformity requiring circumferential fusion. It matters for Medicare payment because the presence of a Major Complication or Comorbidity elevates relative resource use and inpatient reimbursement compared with similar fusion procedures without such severity. Accurate coding of principal and secondary diagnoses and procedure approach determines assignment to this Diagnosis-Related Group.
