G519 – Phlebography and/or carotid pulse tracing - technical component
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Represents the technical component for Phlebography and/or carotid pulse tracing (with systolic time intervals). This is a non-invasive cardiography procedure. The professional component for interpretation and reporting is billed separately under G518. As per , the technical component of this service is subject to a payment adjustment when rendered in a hospital and has specific eligibility rules if the patient is admitted within 24 hours.
When to Use
- Use G519 to bill the technical component when performing carotid pulse tracing to calculate systolic time intervals for cardiac assessment.
- Use this code specifically when you have personally performed the data acquisition and quality assurance for phlebography or pulse tracing, separate from the interpretation billed under G518.
Common Pitfalls
- Billing G519 at the full fee when the procedure is performed in a hospital setting, which triggers an automatic rejection or adjustment to 86.10% of the listed fee.
- Submitting G519 without a corresponding G518 interpretation claim, as the Ministry expects both components to be accounted for in the diagnostic process.
- Failing to maintain the required quality assurance documentation for the technical data acquisition, which is a primary target during Ministry audits.
Billing Tips
- Ensure your billing software is configured to apply the 86.10% payment adjustment automatically when the service location is identified as a hospital to prevent manual reconciliation errors.
