E917 – Ventriculoscopy with interventriculostomy
OHIP Surgical Assists Code — NEUROLOGICAL SURGICAL PROCEDURES · Schedule of Benefits
An add-on procedure to ventriculoscopy (Z825) for the performance of an interventriculostomy. This code is billed in addition to the primary ventriculoscopy procedure.
When to Use
- Use E917 exclusively as an add-on to Z825 (Ventriculoscopy) when an interventriculostomy is performed during the same operative session.
- Apply this code when creating a communication pathway between ventricles (e.g., septostomy) during a neuro-endoscopic procedure.
Common Pitfalls
- Billing E917 as a standalone procedure will result in automatic rejection; it must be submitted on the same claim as Z825.
- Do not use E917 for procedures involving the third ventricle floor (e.g., endoscopic third ventriculostomy), as those are typically covered under different primary codes like Z825 alone or specific E-codes for ETV.
Billing Tips
- Ensure the operative report explicitly details the creation of the interventriculostomy to support the E917 claim in the event of a post-payment audit.
- Verify that the primary procedure Z825 is billed at 100% and E917 is appended to ensure correct processing of the surgical fee.
