2025 ICD-10-CM code Q21.23

Complete atrioventricular septal defect. This is a heart defect present at birth involving a hole in the wall separating all four chambers of the heart.

Not to be used on maternal records. Excludes acquired cardiac septal defect (I51.0) and inborn errors of metabolism (E70-E88).

Complete atrioventricular septal defect is a serious congenital heart defect requiring surgical intervention to correct the defect and prevent long-term complications such as heart failure and pulmonary hypertension. The medical necessity for surgical repair is based on the severity of the defect and the presence of associated complications.

Diagnosis and management of patients with complete atrioventricular septal defect. This includes coordinating care with pediatric cardiologists, cardiac surgeons, and other specialists as needed.

In simple words: A baby's heart has a hole between the upper and lower chambers, and the valves aren't formed correctly.

Complete atrioventricular septal defect. Common atrioventricular canal. Common atrioventricular septal defect. Common endocardial cushion defect. Ostium primum atrial septal defect (type I) with common atrioventricular valve and a moderate or larger inlet VSD.

Example 1: A newborn infant is diagnosed with complete atrioventricular septal defect during a routine echocardiogram., A 6-month-old infant presents with symptoms of heart failure and is subsequently diagnosed with a complete atrioventricular septal defect., A child with Down syndrome undergoes cardiac evaluation and is found to have a complete atrioventricular septal defect.

Echocardiogram findings, cardiac catheterization reports (if performed), genetic testing results (if applicable), and clinical documentation of symptoms and physical exam findings.

** Complete atrioventricular septal defect is often associated with other congenital heart defects and genetic syndromes such as Down syndrome. This condition requires ongoing monitoring and management throughout life.
