N504 – Disc excision (one level)
OHIP Spinal Surgical Procedures Code — SPINAL SURGICAL PROCEDURES · Schedule of Benefits
N504 is for the anterior decompression of the thoracic spine by excising one intervertebral disc. This specific code is used when the thoracotomy portion of the surgery is performed by a separate surgeon. The service is eligible for suffix A (surgeon), B (assistant), and C (anaesthetist). For decompression of an additional level during the same operation, see add-on code E360. If the same surgeon performs both the thoracotomy and the disc excision, use N502.
