E895 – Cerebral arteriovenous malformation greater than 4 cm
OHIP Surgical Assists Code — NEUROLOGICAL SURGICAL PROCEDURES · Schedule of Benefits
When to Use
- Use E895 as an add-on fee when performing a craniotomy for a cerebral arteriovenous malformation (AVM) specifically documented as exceeding 4 cm in diameter.
- Apply this code in conjunction with N106 for supratentorial AVM resections or N155 for infratentorial AVM resections when the size threshold is met.
Common Pitfalls
- Billing E895 without a corresponding N106 or N155 claim will result in an automatic rejection as it is strictly an add-on code.
- Failure to explicitly document the AVM size as greater than 4 cm in the operative report is a primary cause for recovery during OHIP audits.
Billing Tips
- Ensure the operative note clearly references the pre-operative imaging or intraoperative measurement confirming the AVM size to justify the additional complexity fee.
