G293 – Exercise studies during cardiac catheterization
OHIP Diagnostic & Therapeutic Procedures Code · Schedule of Benefits
Exercise studies during cardiac catheterization
When to Use
- Use G293 when performing hemodynamic assessment via catheterization specifically during physical exertion or pharmacological stress simulation.
- Select G293 when evaluating cardiac output or pressure changes in response to exercise in patients with suspected restrictive cardiomyopathy or valvular disease.
Common Pitfalls
- Billing G293 as a standalone procedure when it is performed alongside Z439 or Z440; the additional procedure must be reduced to 50% per the cardiac catheterization group rules.
- Failing to document the specific exercise protocol or hemodynamic data obtained, which is required to justify the G293 fee over standard pressure measurements.
Billing Tips
- Always sequence the primary diagnostic catheterization code (e.g., Z440) at 100% and G293 at 50% when performed in the same session to avoid automatic rejection.
