X139 – Percutaneous nephrostogram
OHIP Laboratory Code — DIAGNOSTIC RADIOLOGY · Schedule of Benefits
Percutaneous nephrostogram is a diagnostic radiology procedure listed with a technical component fee (H) of $21.70 and a professional component fee (P) of $11.10. For definitions and rules regarding technical and professional components, see , , and .
When to Use
- Use X139 for the diagnostic imaging component when performing a percutaneous nephrostogram to evaluate the patency or integrity of an existing nephrostomy tube.
- Use X139 when contrast is injected under fluoroscopic guidance to confirm the position of a nephrostomy catheter, distinct from the procedural insertion code.
Common Pitfalls
- Do not bill X139 in conjunction with interventional procedure codes that already include the diagnostic imaging component in their fee structure.
- Avoid billing X139 if the service is performed as part of a global surgical package where the imaging is considered an integral, non-billable component of the primary procedure.
- Failure to document the technical quality assurance process can lead to the clawback of the technical component (H) during a Ministry audit.
Billing Tips
- Ensure the professional (P) and technical (H) components are billed correctly based on your ownership of the equipment and the location of the service.
- When performing this service on an emergency basis in a hospital setting, verify eligibility for the C-series diagnostic premiums (e.g., C103, C110) to supplement the base fee.
