DRG 518 Overview
DRG 518 covers inpatient cases involving back and neck procedures other than spinal fusion that do not involve a Major Complication or Comorbidity or the placement of a disc device or neurostimulator. Typical procedures include decompression, discectomy without fusion, and other non‑fusion spinal operations focused on symptom relief or neural decompression. This Diagnosis-Related Group groups patients by resource use and clinical similarity, which directly affects Medicare reimbursement for hospitals.
