E905 – Endonasal endoscopic or microscopic approach for surgical access to sella turcica
OHIP Surgical Assists Code — NEUROLOGICAL SURGICAL PROCEDURES · Schedule of Benefits
Endonasal endoscopic or microscopic approach for surgical access to sella turcica - includes when rendered middle turbinate reductions, maxillary antrostomies, ethmoidotomies, ethmoidectomies, sphenoidotomies, septotomy, septoplasty and septal mucosal flap(s) harvest associated with septotomy or sphenoidal mucosal flap(s). This is an add-on to be claimed with N111, N114 or N116 by the surgeon rendering the resection of the lesion(s).
When to Use
- Use E905 when performing an endonasal endoscopic approach to the sella turcica to gain access for a pituitary tumor resection billed under N111, N114, or N116.
- Use E905 to capture the surgical access work, including necessary septoplasty and sphenoidotomy, which are considered inclusive of this code and cannot be billed separately.
Common Pitfalls
- Do not bill any codes from the Respiratory Surgical Procedures or Integumentary System Surgical Procedures sections on the same claim, as E905 explicitly restricts these.
- Avoid billing E905 as a standalone procedure; it is strictly an add-on code and will be rejected if submitted without a primary N111, N114, or N116 claim.
- Do not attempt to unbundle and bill for middle turbinate reductions or ethmoidectomies separately, as these are explicitly listed as included in the E905 fee.
Billing Tips
- Ensure the primary surgical procedure (N111, N114, or N116) is submitted on the same claim as E905 to ensure the add-on logic triggers correctly.
- Verify that the surgeon performing the lesion resection is the same provider claiming E905, as the code is not payable to assisting surgeons or other specialists.
