CPT® Code 81411

Aortic dysfunction or dilation (eg, Marfan syndrome, Loeys Dietz syndrome, Ehler Danlos syndrome type IV, arterial tortuosity syndrome); duplication/deletion analysis panel, must include analyses for TGFBR1, TGFBR2, MYH11, and COL3A1

The CPT® Code 81411 pertains to a molecular genetic testing procedure specifically designed to identify genetic mutations associated with various syndromes that can lead to aortic dysfunction or dilation. This includes conditions such as Marfan syndrome, Loeys Dietz syndrome, Ehlers-Danlos syndrome type IV, and arterial tortuosity syndrome. The testing involves a comprehensive duplication/deletion analysis panel that must include specific analyses for the genes TGFBR1, TGFBR2, MYH11, and COL3A1. These genes are critical as they are linked to the structural integrity of the aorta and other cardiovascular components. The procedure is particularly relevant for patients who exhibit cardiovascular symptoms and skeletal manifestations, which may include craniofacial anomalies. The testing process begins with obtaining a blood sample through venipuncture, which is a separately reportable procedure. The sample is then subjected to advanced genetic testing techniques, including next-generation sequencing and copy number variant analysis, with confirmation provided by Sanger sequencing or droplet digital polymerase chain reaction. This thorough approach allows for the identification of gene mutations that may not only establish a medical diagnosis but also help in identifying carriers of these genetic conditions within families.
