S412 – Nephrectomy - Ectopic Kidney
OHIP Urology Code — Kidney and Upper Urinary Tract · Schedule of Benefits
Nephrectomy of an ectopic kidney is the surgical excision of a kidney that is not located in its usual position. The fee listed is for the primary surgeon (suffix A). Fees for assistant (suffix B) and anaesthetist (suffix C) are calculated based on basic and time units.
When to Use
- Use S412 specifically for the excision of a kidney located in an abnormal anatomical position, such as a pelvic or thoracic kidney.
- Use this code when the ectopic nature of the kidney is the primary surgical challenge, distinguishing it from standard nephrectomy codes like S413 or S415.
Common Pitfalls
- Attempting to bill for a second surgical assistant without prior approval; S412 is not on the pre-approved list for second assistants.
- Failing to document the ectopic location clearly in the operative report, which is required to justify the use of S412 over a standard nephrectomy code.
Billing Tips
- Ensure the operative report explicitly describes the ectopic position to support the higher complexity associated with S412 compared to routine nephrectomy procedures.
