S400 – Laparoscopic placement of probe(s) for ablation of renal tumour
OHIP Urology Code — UROGENITAL AND URINARY SURGICAL PROCEDURES · Schedule of Benefits
Laparoscopic placement of probe(s) for ablation of renal tumour. This is a surgical procedure billed with suffix 'A' for the surgeon. Assistant (suffix 'B') and anaesthetist (suffix 'C') services are calculated based on basic and time units specified in the Schedule of Benefits.
When to Use
- Use S400 for the laparoscopic placement of probes specifically for the purpose of renal tumour ablation.
- Use this code when the procedure is performed laparoscopically; do not use for open surgical approaches which require different procedural codes.
Common Pitfalls
- Billing S400 alongside J069 is prohibited; ensure your claim does not include both codes as they are restricted from being billed together.
- Assuming a second assistant is automatically covered; S400 is not on the pre-approved list for a second assistant, requiring prior authorization and a letter of justification from the surgeon.
Billing Tips
- Ensure the age premium is applied correctly based on the patient's age at the time of the procedure, as these are calculated automatically but must be verified against the Schedule of Benefits age brackets.
- If the procedure is non-elective and performed after hours, ensure the appropriate E-series premium (E409 or E410) is appended to the surgeon's claim to capture the 50% or 75% increase.
