We had an interventional cardiologist perform a percutaneous left heart catheterization, then selective injections of the left ventricle and coronary arteries for diagnostic purposes. This was followed by mechanical thrombectomy of the LAD artery with subsequent drug-eluting stent placement in the LAD. How would we code this?
In a physician setting, you should report 93458-59, 92973, 92928-LD. If the service is performed in a hospital setting, report 93458-59, 92973, C9600-LD. Note It is appropriate to report the documented diagnostic left heart catheterization and associated injections with code 93458 because it is from this data that the decision to intervene was made. Mechanical thrombectomy is reported with add-on code +92973, and the stent deployed within the LAD is reported with code 92928 (for physician billing) or C9600 (for outpatient Medicare hospital billing).
