N530 – Implantation of spinal cord stimulating electrode by laminectomy
OHIP Otolaryngology Code — SPINAL SURGICAL PROCEDURES · Schedule of Benefits
This procedure involves the surgical implantation of a spinal cord stimulating electrode into the spinal column, which requires performing a laminectomy for access. This service is eligible to be billed by the surgeon (suffix A), surgical assistant (suffix B), and anaesthesiologist (suffix C). The assistant is allocated 8 base units and the anaesthetist is allocated 10 base units for fee calculation. See and for details on unit calculation. Note: This service is not eligible for payment when rendered with any decompressive codes, as stated on page of the Schedule.
When to Use
- Use N530 when performing a primary surgical implantation of a spinal cord stimulating electrode that requires a laminectomy for the necessary spinal access.
- Use this code for patients requiring surgical revision or replacement of an electrode if the procedure necessitates a new laminectomy for access.
Common Pitfalls
- Billing N530 in conjunction with any decompressive laminectomy or spinal decompression codes will result in a rejection, as this is explicitly prohibited by the Schedule.
- Failure to document the specific surgical approach requiring laminectomy can lead to audit scrutiny if the claim is flagged for review against decompressive procedure restrictions.
Billing Tips
- Ensure that the surgical assistant (suffix B) and anaesthesiologist (suffix C) are aware of their respective base unit allocations (8 and 10 units) to ensure accurate submission of their claims alongside the surgeon's N530.
