Congenital malformations of great arteries (Q25)
The ICD-10 code section Q25 is designated for congenital malformations of the great arteries, which include various structural heart defects present from birth affecting the aorta and pulmonary arteries. These codes are used to classify specific anomalies such as patent ductus arteriosus, coarctation of the aorta, and atresia or stenosis of the aorta and pulmonary arteries.
The ICD-10 code for congenital malformations of great arteries covers distinct conditions. For example, Q25.0 is specifically used for patent ductus arteriosus, a condition also known by synonyms like familial patent arterial duct and delayed closure of patent arterial duct. Q25.1 identifies coarctation of aorta, including variants such as preductal coarctation. Atresia and stenosis of the aorta and pulmonary artery are coded under Q25.2, Q25.3, Q25.5, and Q25.6. Other codes in this section, such as Q25.45 for double aortic arch or Q25.47 for right aortic arch, help capture more complex or uncommon malformations. These precise codes assist medical coders in accurately identifying congenital heart defects that influence diagnosis, treatment, and medical records, ensuring alignment with clinical terminology including common synonyms like ductus arteriosus aneurysm or interrupted aortic arch.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Endarteritis
Inflammation of the inner endothelial lining (TUNICA INTIMA) of an artery.
Prune Belly Syndrome
A syndrome characterized by abdominal wall musculature deficiency, cryptorchism, and urinary tract abnormalities. The syndrome derives its name from its characteristic distended abdomen with wrinkled skin.
Tetralogy of Fallot
A combination of congenital heart defects consisting of four key features including VENTRICULAR SEPTAL DEFECTS; PULMONARY STENOSIS; RIGHT VENTRICULAR HYPERTROPHY; and a dextro-positioned AORTA. In this condition, blood from both ventricles (oxygen-rich and oxygen-poor) is pumped into the body often causing CYANOSIS.
Tunica Intima
The innermost layer of an artery or vein, made up of one layer of endothelial cells and supported by an internal elastic lamina.
