Z356 – Closure of persistent tracheostoma
OHIP Psychiatric Code — RESPIRATORY SURGICAL PROCEDURES · Schedule of Benefits
Closure of persistent tracheostoma. This is an Independent Operative Procedure (IOP) denoted by the 'Z' prefix. As per , if the major pre-operative visit is rendered in the 12-month period prior to the Z356, only a minor assessment (by a General/Family Physician) or a partial assessment (by a specialist) is payable on the same day. If the major pre-operative assessment is on the same day as the Z356, no other assessment is payable by the same physician on that day.
When to Use
- Use Z356 for the surgical closure of a persistent tracheostoma that has failed to close spontaneously after decannulation.
- Use Z356 when performing a formal surgical excision of the stomal tract and layered closure of the skin and subcutaneous tissues.
Common Pitfalls
- Billing a full consultation or major assessment on the same day as Z356 will trigger an automatic rejection due to its status as an Independent Operative Procedure (IOP).
- Failing to account for the 12-month look-back period for the pre-operative visit; if a major assessment occurred within that year, only a minor or partial assessment is permitted on the day of the procedure.
Billing Tips
- If the procedure is performed non-electively after hours, ensure the appropriate premium (E409A or E410A) is appended to the Z356 claim to maximize the procedural fee.
