N517 – Anterior spinal arthrodesis with instrumentation without decompression - Thoracic - One disc level

OHIP Spinal Surgical Procedures Code — SPINAL SURGICAL PROCEDURES · Schedule of Benefits

This procedure involves an anterior fusion of one thoracic disc level with the use of instrumentation, and does not include decompression. The surgical fee for N517 is inclusive of the thoracotomy approach. For fusion of each additional thoracic disc level during the same operation, see add-on code E366. When the thoracotomy is performed by a separate surgeon, use code N518 instead.
For assistant (B) and anaesthesia (C) services, the start and end times must be documented in the patient's medical record to support the calculation of time units.
If claiming the trauma premium (E420), the medical record must list the Injury Severity Score (ISS).
