Z456 – Insertion of implantable central venous catheter
OHIP Psychiatric Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This service covers the surgical insertion of an implantable central venous catheter. The fee includes the associated pre-operative and post-operative care as defined for surgical procedures in the Schedule of Benefits. Add-on code E684 is payable when this procedure is performed on an infant or child. See also Z457 for removal/repair and Z446 for subcutaneous venous access reservoirs.
When to Use
- Use Z456 for the primary surgical insertion of an implantable central venous catheter, such as a port-a-cath, for long-term venous access.
- Select Z456 specifically for implantable devices; do not use this code for the insertion of non-implantable peripherally inserted central catheters (PICC lines).
Common Pitfalls
- Do not bill Z456 for the removal or repair of an existing catheter; use Z457 for those services instead.
- Avoid confusing Z456 with Z446; Z456 is for the catheter itself, whereas Z446 is specific to the subcutaneous venous access reservoir.
- Failure to include the required letter of justification when billing for a surgical assistant (M400B) will result in automatic rejection.
Billing Tips
- If the patient is under 16 years of age, ensure you append add-on code E684 to the claim to receive the additional flat fee payment.
- When billing for a surgical assistant, use fee code M400B and reference the 6 basic units assigned to Z456 in your supporting documentation.
