S593 – Exploration for undescended testicle, without orchidopexy
OHIP Urology Code — MALE GENITAL SURGICAL PROCEDURES · Schedule of Benefits
S593 is a surgical procedure for the exploration for an undescended testicle, without performing an orchidopexy. This may be indicated when the testicle is absent or atrophic and not viable for repositioning. - Surgeon fee (A-suffix) is for the procedure itself. - Assistant fee (B-suffix) is calculated based on 6 base units plus time units, as per . - Anaesthesia fee (C-suffix) is calculated based on 7 base units plus time units, as per . This procedure can be performed laparoscopically, which makes it eligible for the E792 premium.
When to Use
- Use S593 when surgical exploration confirms the testicle is absent (monorchidism) or atrophic to the point of non-viability, precluding the need for an orchidopexy.
- Use S593 as the primary procedure code when the surgical intent is diagnostic exploration of an undescended testicle and no repositioning or fixation is performed.
Common Pitfalls
- Billing S593 in conjunction with an orchidopexy code (e.g., S591) is a common error; S593 is specifically for cases where no orchidopexy is performed.
- Failure to apply the E792 premium when the exploration is performed laparoscopically results in an automatic 25% underpayment of the surgical fee.
Billing Tips
- Ensure the operative report explicitly documents the absence or non-viability of the testicle to justify the use of S593 over a standard orchidopexy code.
- When performing this laparoscopically, ensure E792 is appended to the claim to trigger the 25% increase on the base fee of $465.20.
