This service is for the insertion of a subclavian or external jugular catheter for the purpose of haemodialysis. It is classified as a Major Invasive Procedure and may be eligible for after-hours procedure premiums under specific conditions.

When to Use

Use G324 for the initial insertion of a subclavian or external jugular catheter specifically for acute haemodialysis access.
Select G324 when performing the procedure in a non-elective setting, such as an urgent need for dialysis in a patient with failed or absent permanent access.

Common Pitfalls

Billing G324 alongside G325 (catheter removal) is often flagged; ensure the clinical record clearly justifies both if performed during the same encounter.
Attempting to bill G324 for internal jugular (IJ) access is a common error, as G324 is specifically restricted to subclavian or external jugular sites; use appropriate alternative codes for IJ insertions.
Failure to append the correct after-hours premium (E409, E410, E412, or E413) when the procedure is performed outside standard hours, resulting in significant lost revenue.

Billing Tips

Always verify the specific site of insertion in your operative note, as OHIP auditors strictly enforce the anatomical requirements defined for G324 versus other central venous access codes.
If the procedure is performed in an emergency department, ensure you use the 'H' prefix and the corresponding ED-specific premium (E412 or E413) to avoid automatic rejection of the claim.
