E891 – Complex endonasal endoscopic resection from frontal or temporal lobe or brainstem
OHIP Surgical Assists Code — NEUROLOGICAL SURGICAL PROCEDURES · Schedule of Benefits
This code represents an add-on fee for a complex endonasal endoscopic resection from the frontal or temporal lobe or brainstem. It is claimed in addition to base procedures N114 or N116.<br><br>Examples of non-pituitary lesions applicable to this service include meningioma, craniopharyngioma, and chordoma. See eligibility rules and billing interactions for payment conditions.
When to Use
- Use E891 as an add-on to N114 or N116 when performing complex endonasal endoscopic resection specifically for non-pituitary lesions like meningiomas, craniopharyngiomas, or chordomas.
- Use this code when the surgical approach involves the frontal lobe, temporal lobe, or brainstem, distinguishing it from simpler pituitary-focused resections.
Common Pitfalls
- Claiming E891 for pituitary-specific lesions will result in rejection, as it is strictly reserved for non-pituitary pathology.
- Attempting to bill for the harvesting of autologous materials (bone, fascia, dermis, or muscle) alongside N114 or N116 is prohibited and will trigger a billing audit.
- Failing to link E891 to the mandatory base procedure (N114 or N116) on the same claim will lead to automatic payment denial.
Billing Tips
- Ensure the pathology report clearly documents the non-pituitary nature of the lesion to support the use of E891 during potential post-payment reviews.
- When performing non-elective procedures after hours, apply E409 or E410 to the base procedure and the E891 add-on fee to maximize the procedural premium.
