OHIP Laboratory Code — DIAGNOSTIC RADIOLOGY · Schedule of Benefits

When to Use
- Use X122 for the performance of a percutaneous trans-hepatic cholangiogram to visualize the biliary tree via direct needle puncture.
- Select X122 when the procedure is performed as a diagnostic radiological intervention, distinct from therapeutic biliary drainage or stenting procedures.
Common Pitfalls
- Billing X122 in conjunction with therapeutic biliary intervention codes may trigger a rejection for unbundling if the radiological imaging is considered part of the primary therapeutic procedure.
- Failure to append the correct suffix (B for assistant, C for anaesthesia) when applicable will result in the omission of eligible premium payments for support staff.
Billing Tips
- Ensure the operative report clearly distinguishes the diagnostic cholangiogram from any subsequent therapeutic maneuvers to justify the use of X122 as a standalone diagnostic service.
