E339 – Endolymphatic shunt or sac decompression
OHIP Surgical Assists Code — Y. Ocular and Aural Surgical Procedures · Schedule of Benefits
This is a surgical procedure for the repair of the inner ear, listed under the Ocular and Aural Surgical Procedures section. The service involves performing an endolymphatic shunt or sac decompression. Payment for this procedure is eligible with A, B, and C suffixes for the surgeon, assistant, and anaesthesiologist respectively. The assistant's fee is calculated based on 6 base units plus time units, and the anaesthesiologist's fee is based on 10 base units plus time units, as detailed in the General Preamble (:99, :106).
When to Use
- Use E339 for the surgical decompression of the endolymphatic sac in patients with refractory Meniere's disease.
- Use E339 when performing an endolymphatic shunt procedure to manage endolymphatic hydrops when medical management has failed.
Common Pitfalls
- Billing E339 in conjunction with other ear procedures without ensuring the surgical approach is distinct and eligible for multiple procedure rules.
- Failing to document the specific surgical technique used, which can lead to audit scrutiny regarding the necessity of the shunt versus simple decompression.
Billing Tips
- Ensure the claim includes the appropriate suffix (A for surgeon, B for assistant, C for anaesthesiologist) to avoid automatic rejection of the surgical fee.
