N130 – Craniotomy plus midline commissurotomy
OHIP Otolaryngology Code — NEUROLOGICAL SURGICAL PROCEDURES · Schedule of Benefits
Craniotomy plus midline commissurotomy is an insured surgical procedure listed in the Neurological Surgical Procedures section of the Schedule of Benefits. The service includes the surgeon's procedure, as well as separate payable services for a surgical assistant and an anaesthesiologist.
When to Use
- Use N130 for the primary surgical approach involving a craniotomy combined with a midline commissurotomy for conditions such as corpus callosotomy.
- Select N130 when the procedure is performed as a distinct neurosurgical intervention, ensuring it is not billed alongside other craniotomy codes that would constitute unbundling.
Common Pitfalls
- Billing N130 with other craniotomy-related codes for the same operative site is a common cause of rejection due to the 'major procedure' rule in the Schedule of Benefits.
- Failure to document the Injury Severity Score (ISS) when attempting to claim the E420 trauma premium will result in automatic rejection of the premium portion of the claim.
Billing Tips
- Ensure the surgical assistant and anaesthesiologist use the appropriate suffix (B and C respectively) to trigger the correct fee calculations and eligibility for the age-based premiums.
