N295 – Excision of Morton’s or subcutaneous neuroma, glomus or small cutaneous nerve tumour
OHIP Otolaryngology Code — NEUROLOGICAL SURGICAL PROCEDURES · Schedule of Benefits
Excision of Morton's or subcutaneous neuroma, glomus or small cutaneous nerve tumour. This procedure is listed in the Neurological Surgical Procedures section under Peripheral Nerves. Add-on code E911 may be claimed for the implantation of the neuroma into bone or muscle.
When to Use
- Use N295 for the surgical excision of a symptomatic Morton's neuroma in the intermetatarsal space.
- Use N295 for the excision of a subcutaneous glomus tumour or a small benign cutaneous nerve tumour (e.g., schwannoma) where the primary intent is the removal of the nerve-associated mass.
Common Pitfalls
- Do not bill N295 for simple skin lesion excisions; the pathology must confirm a neuroma or nerve tumour to withstand an audit.
- Avoid billing N295 in conjunction with N286 for the same anatomical site, as these are typically considered mutually exclusive or bundled procedures.
- Failure to document the use of an operating microscope will lead to the rejection of the 40% premium code E906.
Billing Tips
- Always append E911 if you perform the additional step of burying the proximal nerve stump into bone or muscle to prevent recurrence.
- Ensure the operative report explicitly mentions the use of an operating microscope to justify the E906 premium.
