S234Replacement of percutaneous trans-hepatic catheter

OHIP Urology Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits

This surgical procedure involves the replacement of a percutaneous trans-hepatic catheter used for draining obstructed bile ducts. This service is a follow-up to S233, which covers the initial catheter placement. As per the Schedule of Benefits, this service includes all common elements of insured services as outlined in the General Preamble (, ).

When to Use

  • Use S234 for the routine exchange or replacement of an existing percutaneous trans-hepatic biliary catheter that has become blocked, dislodged, or requires scheduled maintenance.
  • Use S234 when the primary intent is the maintenance of the drainage tract established by the initial procedure coded under S233.

Common Pitfalls

  • Billing S234 in conjunction with S233 on the same day is generally considered unbundling, as S233 is intended for the initial placement and S234 for subsequent maintenance.
  • Failure to distinguish between a simple catheter exchange (S234) and more complex interventional procedures that may require different, higher-valued surgical codes.

Billing Tips

  • Ensure the procedural note clearly distinguishes this as a replacement of an existing catheter rather than an initial placement to avoid audit triggers related to S233.
  • Apply relevant age-based premiums if the patient is under 16, as these are frequently overlooked for surgical procedures.
