Z480 – Cystotomy with trochar and cannula and insertion of tube
OHIP Psychiatric Code — UROGENITAL AND URINARY SURGICAL PROCEDURES · Schedule of Benefits
Cystotomy with trochar and cannula and insertion of tube is a surgical procedure listed under the Incision of the Bladder subcategory. It is eligible for surgeon and anaesthetist fees, with anaesthesia calculated based on 6 base units plus time units. Assistant services require independent consideration.
When to Use
- Use Z480 for the percutaneous placement of a suprapubic catheter via trocar and cannula when an open cystotomy is not required.
- Use this code for urgent bladder drainage in patients with acute urinary retention where urethral catheterization has failed or is contraindicated.
Common Pitfalls
- Do not bill Z480 in addition to an open cystostomy procedure code; it is intended for the specific trocar-based technique.
- Avoid billing Z480 if the procedure is performed as part of a more extensive bladder surgery, as it may be considered an integral component of the primary procedure.
- Failure to document the specific use of a trocar and cannula can lead to audit scrutiny if the procedure is miscoded as a more complex open surgical intervention.
Billing Tips
- If a surgical assistant is required, you must submit the claim using M400B and include a letter of justification from the surgeon to the medical consultant for approval.
- Ensure the E750 add-on code is applied if Z480 is performed in conjunction with another eligible procedure to maximize the claim value.
