N127 – Re-opening of craniotomy for post-operative haematoma or for removal of bone flap
OHIP Otolaryngology Code — NEUROLOGICAL SURGICAL PROCEDURES · Schedule of Benefits
Re-opening of craniotomy for post-operative haematoma or for removal of bone flap is a neurological surgical procedure. This procedure is performed when it's necessary to access a previous surgical site in the skull, typically to address complications like bleeding (haematoma) that may occur after surgery, or for the scheduled removal of the bone flap.
When to Use
- Use for the urgent surgical evacuation of a post-operative intracranial haematoma that requires reopening the original craniotomy site.
- Use for the planned, secondary surgical procedure to remove a bone flap that was previously placed during a primary craniotomy.
Common Pitfalls
- Do not bill N127 if the procedure is part of the global surgical period for the primary craniotomy, unless the re-opening is for a distinct, non-routine complication like a haematoma.
- Avoid using N127 for initial craniotomy procedures; it is strictly for re-opening or secondary flap management, not the primary access.
Billing Tips
- Ensure the operative report clearly distinguishes the re-opening procedure from the primary surgery to justify the additional fee and avoid global period denials.
- If the re-opening is performed on an emergency basis, ensure the appropriate after-hours premium (E409 or E410) is appended to the claim to reflect the urgency.
