Ask Dr. Z

In our practice it's common to have one of our cardiologists perform the heart catheterization and the interventional cardiologist perform the intervention (like a stent) for the same patient, same procedure. Both cardiologists dictate their own OP report while referring to the other's work. Example: "See Dr. A's report for diagnostic cath details" or "See Dr. B's report for PCI". We have no trouble getting our claim processed when the intervention is a stand-alone code, but our claims for add-on codes like an FFR are being rejected. Is there a way to report the diagnostic cath on the interventional claim that acknowledges that a diagnostic cath was performed along with the FFR but by another physician at the same time?
