What 93574 covers
During cardiac catheterization, the cardiologist positions a catheter to selectively inject contrast into pulmonary veins and records images that show venous anatomy and blood flow. The study may help evaluate suspected pulmonary vein narrowing or obstruction, or define abnormal venous drainage. It is typically performed in a cardiac catheterization laboratory by a cardiologist experienced in invasive imaging.
Report 93574 only with a primary catheterization procedure; it is an add-on, not a stand-alone service. Documentation should identify the selectively catheterized pulmonary vein or veins, the clinical reason for imaging, the contrast injection and resulting images, and the interpretation. The imaging supervision, interpretation, and report are part of this angiographic service. CMS pays this add-on within the global period of the primary procedure, so it is not paid as a separate service outside that procedure’s global period.
