E898
E898 – Lesion greater than 2.5 cm
OHIP Surgical Assists Code — NEUROLOGICAL SURGICAL PROCEDURES · Schedule of Benefits
When to Use
- Use E898 as an add-on code when the lesion size excised or treated via N105 (Excision of lesion of scalp) or N154 (Excision of lesion of skull) exceeds 2.5 cm in diameter.
- Apply this code specifically when the surgical report explicitly documents the lesion measurement as greater than 2.5 cm to justify the additional complexity fee.
Common Pitfalls
- Billing E898 without an associated primary procedure code (N105 or N154) will result in an automatic rejection.
- Attempting to bill E898 for lesions 2.5 cm or smaller is a common audit trigger; the measurement must exceed the 2.5 cm threshold to qualify.
- Failing to document the specific dimensions of the lesion in the operative note makes this code non-payable upon post-payment audit.
Billing Tips
- Ensure the operative report clearly states the lesion size in centimeters, as 'large' or 'extensive' are insufficient descriptors for OHIP verification.
