N532 – C1/C2 screw fixation
OHIP Otolaryngology Code — SPINAL SURGICAL PROCEDURES · Schedule of Benefits
Posterior spinal arthrodesis as a sole procedure with instrumentation for the cervical spine. This service involves / screw fixation using transarticular, pedicle, or lateral mass techniques. Additional levels may be fused using add-on codes. The service is eligible for surgeon (A), assistant (B), and anaesthetist (C) suffixes, with specific base units applicable for assistant and anaesthesia services.
When to Use
- Use N532 for primary C1/C2 transarticular or pedicle screw fixation when performed as the definitive stabilization procedure.
- Select N532 when the surgical intent is posterior arthrodesis of the atlanto-axial complex with instrumentation as the primary service.
Common Pitfalls
- Claiming N515 alongside N532 will trigger an automatic reduction of N515 to the lower-valued E366 fee.
- Failing to use the appropriate add-on codes (E366, E371, or E377) for additional levels fused, which results in under-billing for multi-level procedures.
Billing Tips
- Always append the correct assistant (B) and anaesthetic (C) suffixes to ensure the base units are calculated correctly for the procedure complexity.
- When extending the fusion beyond C1/C2, ensure the additional levels are billed exclusively using the designated add-on codes to avoid claim rejections or payment adjustments.
