N150 – C.S.F. leak - intracranial repair
OHIP Otolaryngology Code — NEUROLOGICAL SURGICAL PROCEDURES · Schedule of Benefits
C.S.F. leak - intracranial repair (to include trans-sphenoidal approach)
When to Use
- Use N150 for the definitive surgical repair of a dural defect causing a CSF leak, specifically when utilizing a trans-sphenoidal approach.
- Use N150 for intracranial repair of CSF leaks resulting from trauma or previous neurosurgical procedures where the dural breach requires formal closure.
Common Pitfalls
- Do not bill N150 for simple nasal packing or conservative management of a CSF leak; it is strictly a surgical procedure code.
- Avoid billing N150 in conjunction with other intracranial procedures unless the dural repair is a distinct, separate surgical objective, as it may be considered bundled into the primary craniotomy fee.
Billing Tips
- Ensure the operative report explicitly details the dural defect location and the specific repair technique used to justify the N150 fee in the event of an audit.
- If the repair is performed as part of a larger, more complex procedure, ensure you are not violating the Multiple Procedure Rule by checking if the primary procedure already includes dural closure.
