N582
N582 – One disc level
OHIP Otolaryngology Code — SPINAL SURGICAL PROCEDURES · Schedule of Benefits
When to Use
- Use N582 as the primary code for a single-level posterior lumbar spinal arthrodesis involving instrumentation.
- Use N582 when performing the base procedure before adding E366 for every additional lumbar disc level fused.
- Use N582 in conjunction with E387 when the fusion construct specifically extends to the sacrum.
Common Pitfalls
- Billing N582 multiple times for multi-level procedures instead of using the base code N582 plus the appropriate number of E366 units.
- Failing to document the specific instrumentation used, which is a mandatory requirement for the N582 fee classification.
- Attempting to bill N582 with other spinal procedure codes that are considered inclusive or mutually exclusive under the Schedule of Benefits.
Billing Tips
- Always append E366 for each additional level beyond the first to ensure you are compensated for the full extent of the multi-level fusion.
- Verify that your operative report clearly distinguishes between the primary level (N582) and subsequent levels (E366) to prevent audit rejections.
