HeartFlow Inc. announced that Health Care Service Corp. (HCSC), which operates Blue Cross and Blue Shield plans in five states, has issued a medical policy for the HeartFlow FFRct Analysis, a non-invasive technology that helps clinicians diagnose and treat patients with suspected coronary artery disease (CAD). HCSC — which operates Blue Cross Blue Shield plans in Illinois, Montana, New Mexico, Oklahoma and Texas — has determined that the use of noninvasive fractional flow reserve (FFR) following a positive coronary computed tomography (CT) angiogram may be considered medically necessary to guide decisions about the use of invasive coronary angiography in patients with stable chest pain at intermediate risk of CAD.
