Code Description

ICD-10 Q20.1 is a billable code used to indicate a diagnosis of double outlet right ventricle.

Key Diagnostic Point:

Double outlet right ventricle (DORV) is a congenital heart defect characterized by both the aorta and pulmonary artery arising from the right ventricle, rather than the normal configuration where the aorta arises from the left ventricle. This condition can lead to significant hemodynamic abnormalities, as the systemic and pulmonary circulations are not properly separated. DORV may present with various associated anomalies, including ventricular septal defects (VSDs) and other structural heart defects. The clinical presentation can vary widely, from asymptomatic cases detected incidentally to severe cyanosis and heart failure in neonates. Diagnosis typically involves echocardiography, which provides visualization of the heart's structure and blood flow. Management often requires surgical intervention to correct the anatomical defects and improve blood flow, with the timing of surgery being critical for optimal outcomes. Long-term follow-up is essential due to the risk of complications such as arrhythmias and heart failure as the child grows.
