N507 – Vertebrectomy (removal of vertebral body and excision of adjacent discs)
OHIP Otolaryngology Code — SPINAL SURGICAL PROCEDURES · Schedule of Benefits
Anterior spinal decompression of the lumbar spine via vertebrectomy. This procedure involves the removal of the vertebral body and the excision of adjacent discs. The service includes the laparotomy/retroperitoneal approach. For decompression of additional levels, E360 may be claimed. For a combined thoracotomy/laparotomy approach, E362 may be claimed.
When to Use
- Use N507 for anterior lumbar spinal decompression requiring the formal removal of a vertebral body and excision of adjacent discs via a laparotomy or retroperitoneal approach.
- Use N507 as the primary procedure code when performing a multi-level vertebrectomy, with subsequent levels claimed using E360.
Common Pitfalls
- Do not attempt to bill N507 for anterior cervical procedures; N569 is the appropriate code for cervical decompression, and N507 is strictly for the lumbar spine.
- Avoid billing E360 for the first level of decompression; the primary fee for N507 already covers the first level, and E360 is strictly for additional levels only.
- Failure to document the specific approach (laparotomy/retroperitoneal) can lead to audit scrutiny, as this is a required element of the N507 definition.
Billing Tips
- If the procedure requires a combined thoracotomy and laparotomy approach, ensure E362 is added to the claim to capture the additional complexity of the dual-cavity access.
- Always verify that the patient's Injury Severity Score (ISS) is documented in the medical record before applying the E420 trauma premium to N507.
