E389
E389 – Additional level of scoliosis correction over six levels
OHIP Surgical Assists Code — SPINAL SURGICAL PROCEDURES · Schedule of Benefits
When to Use
- Use for long-segment posterior spinal instrumentation and fusion where the total number of levels instrumented exceeds six.
- Apply for each individual vertebral level beyond the sixth level included in the base N540 procedure.
Common Pitfalls
- Billing E389 as a standalone code; it must be submitted on the same claim as N540 to avoid automatic rejection.
- Miscounting the total number of levels instrumented, leading to over-billing or under-billing of the add-on units.
- Failing to specify the exact number of units of E389 claimed, which must correspond precisely to the levels documented in the operative report.
Billing Tips
- Ensure the operative report explicitly lists every vertebral level involved in the correction to justify the total number of E389 units billed.
- Calculate the number of E389 units by subtracting six from the total number of levels corrected (e.g., a 10-level correction requires N540 plus 4 units of E389).
