Z464 – Declotting by cannula, any method
OHIP Psychiatric Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Declotting of an arterio-venous (AV) fistula or graft by cannula, using any method. This service includes the placement of the cannula, administration of contrast and/or therapeutic agent(s), and any image guidance rendered at the time of the procedure. Obtaining and interpreting any images in conjunction with Z464 are not eligible for payment to any physician.
When to Use
- Use Z464 for the mechanical or pharmacological declotting of an AV fistula or graft via cannula insertion.
- Use this code when the procedure is performed as a standalone therapeutic intervention for a thrombosed access site.
Common Pitfalls
- Do not bill for image guidance or diagnostic imaging (e.g., R941-R946) separately, as these are explicitly included in the Z464 fee.
- Avoid billing Z464 in conjunction with surgical assistant or anaesthesia fees, as these are strictly prohibited by the Schedule of Benefits.
- Do not attempt to unbundle the procedure by billing for the cannula placement or contrast administration as separate minor procedures.
Billing Tips
- Ensure the claim includes the appropriate age-based premium if the patient meets the criteria, as Z464 is classified as a surgical procedure.
- If the declotting is performed in an emergency or after-hours setting, apply the relevant E-code premium (E409-E413) to the Z464 fee to maximize reimbursement.
