N561
N561 – Intradural intramedullary spinal tumour(s) - partial or total removal
OHIP Otolaryngology Code — SPINAL SURGICAL PROCEDURES · Schedule of Benefits
Intradural intramedullary spinal tumour(s) - partial or total removal.
When to Use
- Use N561 for the surgical resection of intradural intramedullary spinal tumors, such as ependymomas or astrocytomas, where the pathology is located within the spinal cord substance.
- Select N561 when the primary surgical objective is the partial or total removal of a lesion that requires a myelotomy for access, distinguishing it from extramedullary lesions covered under N560.
Common Pitfalls
- Billing N560 and N561 together is a common error; these codes are mutually exclusive and the Ministry will reject the secondary code.
- Attempting to bill additional spinal decompression codes alongside N561 will result in payment rejection, as the fee for N561 is considered inclusive of the necessary surgical approach and decompression.
- Failure to document the use of synthetic or autologous tissue for duroplasty will result in the loss of the E382 add-on fee, which is only payable when explicitly supported by the operative report.
Billing Tips
- Always append the E382 add-on code if a spinal duroplasty is performed during the same operative session, provided the criteria for autologous, allogenic, or synthetic tissue are met.
- Ensure that the E383 acute spinal cord injury premium is only applied when the clinical documentation explicitly confirms an acute spinal cord injury context, as this is subject to audit verification.
