N283 – Decompression for thoracic outlet syndrome
OHIP Otolaryngology Code — NEUROLOGICAL SURGICAL PROCEDURES · Schedule of Benefits
Decompression, for thoracic outlet syndrome including excision of cervical and/or first rib and scalenotomy
When to Use
- Use N283 when performing a formal thoracic outlet decompression that explicitly includes the excision of a cervical rib or the first rib combined with a scalenotomy.
- Use this code for the surgical management of neurogenic thoracic outlet syndrome where the primary objective is the decompression of the brachial plexus through rib resection.
Common Pitfalls
- Do not bill N283 in conjunction with other peripheral nerve decompression codes if the work is already encompassed by the thoracic outlet decompression procedure.
- Avoid billing N283 if only a scalenotomy is performed without the required rib excision, as this may not meet the full criteria for this specific fee code.
- Failure to document the use of an operating microscope will result in the rejection of the E906 premium, even if the procedure was performed under magnification.
Billing Tips
- Ensure the operative report clearly details both the scalenotomy and the specific rib(s) excised to justify the N283 fee during a potential audit.
- If performing a repeat decompression on the same site, ensure E925 is applied to capture the 30% increase for repeat peripheral nerve procedures.
