Z632 – Excision of single bladder tumour 1 to 2 cm diameter
OHIP Psychiatric Code — UROGENITAL AND URINARY SURGICAL PROCEDURES · Schedule of Benefits
Excision of a single bladder tumour that is 1 to 2 cm in diameter. The procedure includes removal of the tumour base and adjacent muscles, with electrocoagulation if necessary. A separate claim for diagnostic cystoscopy (e.g. Z606) is not payable when performed at the same time.
When to Use
- Use for the transurethral resection of a single bladder tumour measuring between 1 cm and 2 cm in diameter.
- Use when the procedure includes the resection of the tumour base and adjacent muscle tissue, regardless of whether electrocoagulation is required.
Common Pitfalls
- Attempting to bill a diagnostic cystoscopy (Z606) in addition to Z632 is a common rejection, as the cystoscopy is considered bundled into the excision fee.
- Billing Z632 for multiple tumours or tumours outside the 1-2 cm size range, which requires different codes such as Z633 or Z634.
- Failure to document the specific size of the tumour in the operative report, which is necessary to justify the use of Z632 over other excision codes.
Billing Tips
- Ensure the operative note explicitly states the tumour size, as this is the primary determinant for selecting Z632 versus Z633 or Z634.
- If performing an excision of a single tumour alongside other unrelated urological procedures, ensure the claim reflects only the bundled Z632 fee to avoid audit flags regarding unbundling.
