N554 – Radical soft tissue tumour excision 5cm and greater
OHIP Otolaryngology Code — SPINAL SURGICAL PROCEDURES · Schedule of Benefits
This service covers the radical excision of a soft tissue tumour associated with the spine, where the tumour measures 5 centimeters or greater. It is a surgical procedure with fees calculated based on units for the surgeon, assistant, and anaesthetist. This service requires that the tumour be 5cm or greater. The assistant fee is based on 9 base units plus time units, and the anaesthetist fee is based on 13 base units plus time units.
When to Use
- Use N554 for the radical excision of a soft tissue tumour directly associated with the spine when the pathology report or intraoperative measurement confirms the tumour size is 5cm or greater.
- Select N554 over N553 when the tumour size threshold of 5cm is met, as N553 is intended for smaller soft tissue tumours in the spinal region.
Common Pitfalls
- Billing N554 without explicit documentation of the tumour size in the operative report, which is a common trigger for post-payment audit recovery.
- Attempting to bill N554 for superficial skin or subcutaneous lesions that are not anatomically associated with the spine or deep soft tissue structures.
Billing Tips
- Ensure the operative note clearly describes the anatomical relationship to the spine and the measured size of the tumour to justify the use of the N554 code over lower-valued excision codes.
