Summary & Overview
Single Level Spinal Fusion Except Cervical without MCC: Inpatient Reimbursement Overview
DRG 451 encompasses single level spinal fusion procedures outside the cervical spine without a Major Complication or Comorbidity; it addresses resource use for single-segment lumbar or thoracolumbar fusions. Proper classification into this Diagnosis-Related Group matters for inpatient reimbursement because the assigned Diagnosis-Related Group determines the Medicare prospective payment for the hospital stay.
DRG 451 Overview
DRG 451 covers single level spinal fusion procedures outside the cervical region without a Major Complication or Comorbidity and is commonly assigned for lumbar or thoracolumbar fusion at one motion segment. This Diagnosis-Related Group captures cases where the primary surgical intervention is a single-level posterior, anterior, or combined approach spinal fusion without high-severity comorbid conditions. It matters for Medicare payment because the Diagnosis-Related Group assignment drives the inpatient prospective payment amount, influencing hospital reimbursement for resource use associated with operative time, implants, and postoperative care. Accurate coding of diagnoses and procedures determines whether a case is grouped to DRG 451 versus other fusion-related or higher-severity Diagnosis-Related Groups.
