G301 – Exercise studies during catheterization
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Performance of exercise studies during a cardiac catheterization procedure. This diagnostic service is listed under the Cardiovascular subsection of Diagnostic and Therapeutic Procedures.
When to Use
- Use G301 specifically when hemodynamic measurements are taken during active exercise provocation while the patient is undergoing a cardiac catheterization.
- Apply this code when the exercise study is performed as an adjunct to the primary catheterization procedure to assess cardiac output or pressure changes under stress.
Common Pitfalls
- Do not bill G301 for standard resting hemodynamic assessments, which are typically included in the base catheterization procedure codes like G299 or G300.
- Avoid billing G301 if the exercise study is performed as a standalone stress test outside of the catheterization suite, as this code is strictly for intra-procedural use.
Billing Tips
- Ensure the procedural report explicitly documents the exercise protocol and the specific hemodynamic data points captured during the stress phase to justify the additional fee.
