G285 – Dye dilution densitometry
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Dye dilution densitometry performed in a cardiac catheterization laboratory using a Swan-Ganz catheter. This service is an add-on to Z438. It is part of a series of cardiac catheterization procedures that includes insertion of catheter (including cutdown and repair of vessels if rendered), catheter placement, contrast injection, imaging and interpretation.
When to Use
- Use G285 specifically when performing dye dilution cardiac output measurements during a cardiac catheterization procedure where a Swan-Ganz catheter (Z438) has been placed.
- Apply this code when the densitometry is performed as an adjunct to the primary hemodynamic assessment in the cardiac catheterization laboratory.
Common Pitfalls
- Billing G285 without an associated Z438 claim will result in a rejection, as it is strictly an add-on procedure.
- Failing to apply the 50% reduction rule when multiple cardiac catheterization procedures (Z439-G288) are performed in the same session is a common audit trigger.
Billing Tips
- Ensure the claim for G285 is submitted in the same batch as Z438 to maintain the required procedural link for the cardiac catheterization session.
