S408 – Pyelolithotomy - Open
OHIP Urology Code — Kidney and Upper Urinary Tract · Schedule of Benefits
S408 represents an open pyelolithotomy, a surgical intervention for the removal of stones from the renal pelvis of the kidney. This procedure is performed via an open incision and is eligible for surgeon, assistant, and anaesthetist fees, which are calculated based on a combination of basic and time units.
When to Use
- Use S408 for open surgical removal of renal pelvic calculi when minimally invasive options like ureteroscopy or percutaneous nephrolithotomy are contraindicated or technically unfeasible.
- Select S408 when the surgical approach requires an open flank incision to access the renal pelvis for stone extraction.
Common Pitfalls
- Billing S408 in conjunction with endoscopic stone removal codes (e.g., S414) is a common audit trigger; ensure the operative report clearly justifies the open approach.
- Failure to document the specific anatomical location of the stone within the renal pelvis can lead to claims being flagged for review against less invasive procedure codes.
Billing Tips
- Ensure that after-hours premiums (E409 or E410) are only applied if the procedure meets the non-elective criteria or was delayed by an intervening surgical emergency.
- When billing for the assistant, ensure the assistant's claim is submitted with the corresponding after-hours premium (E400B or E401B) to match the surgeon's commencement time.
