Z784 – Excision and suture of rectal or sigmoid polyp or tumour - base 2 to 5 cm, inclusive
OHIP Psychiatric Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This service is for the excision and suture of a polyp or tumour of the rectum or sigmoid with a base measuring 2 to 5 cm, inclusive. As a '#' prefixed code, when performed in a hospital, the provision of premises, equipment, supplies, and personnel are funded by the hospital global budget and are not billed separately (see ). Payment is limited to a maximum of 2 procedures for polyps or tumours of the rectum or sigmoid per day, regardless of size or technique.
When to Use
- Use Z784 for the formal surgical excision and suture of a rectal or sigmoid polyp or tumour with a measured base between 2 cm and 5 cm.
- Select this code when the procedure involves a formal surgical approach (e.g., transanal or trans-sacral) rather than endoscopic fulguration or excision, which are governed by the S19 colonoscopy fee schedule.
Common Pitfalls
- Billing Z784 for endoscopic procedures is a common audit trigger; ensure the procedure was a formal surgical excision and not a colonoscopic removal.
- Exceeding the daily limit of two procedures per patient will result in automatic rejection of the third claim, regardless of the clinical complexity.
- Failure to document the specific base measurement (2-5 cm) in the operative report creates a significant risk during post-payment review, as this is the primary criterion for selecting Z784 over Z783 or Z785.
Billing Tips
- If laser debulking is performed as part of the procedure, ensure E688 is billed as an add-on to maximize the claim value.
- Always verify that the base size is clearly stated in the pathology or operative report to justify the 2-5 cm range, as this distinguishes Z784 from smaller (Z783) or larger (Z785) excision codes.
