2025 ICD-10-CM code Q21.21
(Active) Effective Date: N/A Revision Date: N/A Congenital malformations of the circulatory system - Congenital malformations of cardiac septa 7 (Q00-Q99) Congenital malformations, deformations and chromosomal abnormalities Feed
Partial atrioventricular septal defect.
Medical necessity for intervention is determined by the severity of the defect and its impact on the patient's health. Significant shunting of blood, symptoms of heart failure, and growth delays justify medical or surgical treatment.
Diagnosis and management of patients with congenital heart defects falls under pediatric cardiologists. Other specialists, such as cardiac surgeons, may be involved depending on the severity and required interventions. Primary care physicians play a role in initial detection and referral.

- Q21 Congenital malformations of cardiac septaQ21.2 Partial atrioventricular septal defectQ21.21 Partial atrioventricular septal defect
In simple words: This code describes a heart defect present at birth where the wall separating the heart's upper chambers (atria) and the valves controlling blood flow between the atria and ventricles isn't fully formed.
Partial atrioventricular septal defect. Incomplete atrioventricular canal. Incomplete atrioventricular septal defect. Incomplete endocardial cushion defect. Ostium primum atrial septal defect (type I) with separate atrioventricular valves. Partial atrioventricular canal. Partial endocardial cushion defect.
Example 1: A newborn infant is diagnosed with a heart murmur during a routine checkup. An echocardiogram confirms the presence of a partial atrioventricular septal defect. The infant is monitored regularly by a pediatric cardiologist., A 6-month-old child experiences shortness of breath and difficulty feeding. Diagnostic tests reveal a partial atrioventricular septal defect that requires surgical repair., An adult patient is found to have a previously undiagnosed partial atrioventricular septal defect during an unrelated medical evaluation. The patient is referred to a cardiologist for further assessment and management.
Documentation should include a detailed description of the defect based on imaging studies (e.g., echocardiogram, cardiac MRI), clinical findings (e.g., heart murmur, symptoms of heart failure), and any associated conditions. Details regarding surgical intervention, if performed, are also important.
