Z620 – Dilatation of urethra - female, general anaesthetic
OHIP Psychiatric Code — UROGENITAL AND URINARY SURGICAL PROCEDURES · Schedule of Benefits
This billing code represents a surgical procedure for the dilatation of the urethra in a female patient, performed under general anaesthetic. It is listed under Urogenital and Urinary Surgical Procedures in the Schedule of Benefits.
When to Use
- Use Z620 when performing a formal surgical dilatation of the female urethra requiring general anaesthesia to address urethral stenosis or stricture.
- Select Z620 over Z615 (urethral dilatation, local anaesthetic) when the clinical complexity or patient tolerance necessitates a general anaesthetic.
Common Pitfalls
- Do not bill Z620 on the same day as Z615; Z620 will be paid at nil if Z615 is claimed for the same patient on the same day.
- Avoid billing Z620 if the procedure is performed as part of a more comprehensive urological surgery, as it may be considered bundled into the primary procedure code.
Billing Tips
- Ensure the anaesthetist includes the appropriate E-series anaesthesia modifier codes (e.g., E022C for ASA III) to supplement the base units, as Z620 is a surgical procedure code and does not include anaesthesia time units.
- If the procedure is cancelled after anaesthesia induction but before the dilatation begins, claim E006C instead of Z620 to capture the anaesthetic service provided.
