G306 – Isotope studies during cardiac catheterization
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Isotope studies during cardiac catheterization.
When to Use
- Use G306 specifically when performing isotope-based diagnostic imaging during a cardiac catheterization procedure to assess myocardial perfusion or viability.
- Select G306 when the isotope study is integrated into the catheterization session, distinguishing it from standalone nuclear cardiology studies billed under different diagnostic sections.
Common Pitfalls
- Billing G306 in conjunction with G299 or G300 for the same patient encounter often triggers a rejection for duplicate diagnostic service reporting.
- Failure to document the specific isotope used and the intra-procedural timing can lead to audit recovery if the service is flagged as a non-essential add-on.
Billing Tips
- Ensure the procedural report clearly differentiates the isotope study from the base catheterization codes like G289 or G293 to justify the additional fee.
