DRG 402 Overview
DRG 402 covers inpatient admissions for single level combined anterior and posterior spinal fusion procedures outside the cervical region. This captures complex thoracic or lumbosacral fusion operations that involve both anterior and posterior approaches at a single spinal level. It matters for Medicare payment because the surgical approach and resource intensity influence the Diagnosis-Related Group assignment and consequent Medicare Severity Diagnosis-Related Group reimbursement. Proper classification affects hospital payment for operative care, supply use, and length of stay.
