Z449 – Percutaneous angioplasty for coarctation of aorta
OHIP Psychiatric Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Percutaneous angioplasty for coarctation of aorta. This service includes angiography with or without pressure measurements as per the note on page ().
When to Use
- Use Z449 for the primary percutaneous balloon angioplasty procedure performed to treat a native or recurrent coarctation of the aorta.
- Use this code when the procedure includes the mandatory diagnostic components of angiography and pressure measurements, as these are bundled into the Z449 fee.
Common Pitfalls
- Do not bill separately for diagnostic angiography or pressure measurements, as these are explicitly included in the Z449 service definition.
- Avoid billing Z449 in conjunction with other surgical procedure codes unless a distinct, unrelated procedure is performed, as this may trigger a claim rejection for unbundling.
- Failure to apply the correct age-based premium (e.g., under 30 days or under 1 year) results in significant underpayment, as these premiums are specifically designed for pediatric cardiovascular interventions.
Billing Tips
- Ensure the patient's age is accurately reflected in the claim to automatically trigger the appropriate percentage increase from the age-based premium list.
- When performing the procedure after hours, ensure the claim includes the correct E409 or E410 premium code to capture the 50% or 75% increase, provided the procedure meets the non-elective criteria.
