Atrioventricular septal defect, unspecified as to partial or complete
ICD-10 Q21.20 is a billable code used to indicate a diagnosis of atrioventricular septal defect, unspecified as to partial or complete.
Atrioventricular septal defect (AVSD) is a congenital heart defect characterized by a combination of atrial septal defect (ASD) and ventricular septal defect (VSD), leading to a single common atrioventricular valve instead of separate mitral and tricuspid valves. This condition results in abnormal blood flow between the heart chambers, causing increased pulmonary blood flow and potential heart failure if not treated. AVSD can be classified into two types: complete and partial, but when unspecified, it indicates that the exact nature of the defect is not determined. Symptoms may include difficulty breathing, poor feeding, and failure to thrive in infants. Diagnosis is typically made through echocardiography, which visualizes the heart's structure and function. Management often requires surgical intervention to repair the defect and restore normal hemodynamics, with follow-up care essential for monitoring potential complications such as arrhythmias or pulmonary hypertension.
Detailed clinical notes on symptoms, diagnostic imaging results, and treatment plans.
Infants presenting with failure to thrive, respiratory distress, or heart murmurs.
Pediatric patients may require ongoing monitoring for growth and development post-repair.
Family history of congenital heart defects and genetic testing results if applicable.
Patients with syndromic presentations such as Down syndrome, which is commonly associated with AVSD.
Genetic counseling may be necessary for families with a history of congenital anomalies.
Used during surgical intervention for AVSD.
Operative reports detailing the surgical approach and findings.
Pediatric cardiology should provide detailed surgical notes.
Complete AVSD involves a single common atrioventricular valve with both atrial and ventricular septal defects, while partial AVSD has a separate mitral valve but still includes a ventricular septal defect. Accurate coding requires understanding these distinctions.
