Z606 – Diagnostic cystoscopy
OHIP Psychiatric Code — UROGENITAL AND URINARY SURGICAL PROCEDURES · Schedule of Benefits
Performs a diagnostic cystoscopy, which is a visual examination of the interior of the bladder using a cystoscope, with or without an accompanying urethroscopy (examination of the urethra). As a surgical procedure, payment is subject to the rules for surgeon (suffix A), assistant (suffix B), and anaesthetist (suffix C). The service includes all common elements of insured services as described in -. Several therapeutic procedures can be performed during the same session and are billable as add-ons. Specific payment rules and restrictions apply, particularly regarding anaesthesia services and co-billing with other bladder tumour procedures.
When to Use
- Use Z606 for a standalone diagnostic cystoscopy performed to investigate hematuria, recurrent urinary tract infections, or lower urinary tract symptoms.
- Use Z606 when performing a visual inspection of the bladder mucosa that does not involve the excision, biopsy, or fulguration of bladder tumours.
Common Pitfalls
- Do not bill Z606 in addition to Z632, Z633, or Z634, as the diagnostic cystoscopy is considered an inclusive component of bladder tumour excision procedures.
- Anaesthetists must adhere to the 5-unit base fee specified on page T9, as billing time units or extra units for Z606C will result in automatic rejection or recovery.
- Avoid billing E003C for anaesthesia services, as it is explicitly disallowed for Z606 procedures.
Billing Tips
- When acting as an assistant, bill M400B rather than attempting to bill a percentage of the Z606A fee, ensuring the claim includes the required medical consultant authorization.
- If performing a non-elective procedure after 17:00 or on weekends, apply the E409 add-on to the surgical fee to capture the 50% premium.
