Sinus venosus atrial septal defect, unspecified
ICD-10 Q21.16 is a billable code used to indicate a diagnosis of sinus venosus atrial septal defect, unspecified.
Sinus venosus atrial septal defect (SVASD) is a rare congenital heart defect characterized by an abnormal opening between the right atrium and the left atrium, resulting from improper development of the atrial septum during embryogenesis. This defect is often associated with abnormal pulmonary venous return, where one or more pulmonary veins drain into the right atrium instead of the left atrium. Patients with SVASD may present with symptoms such as exercise intolerance, fatigue, and palpitations, particularly as they age. The condition can lead to right atrial and ventricular enlargement, pulmonary hypertension, and increased risk of atrial arrhythmias. Diagnosis typically involves echocardiography, which can visualize the defect and assess hemodynamic significance. Management may include surgical repair or catheter-based interventions, particularly in symptomatic patients or those with significant shunting. Early detection and intervention are crucial to prevent long-term complications associated with this defect.
Detailed pediatric history, including prenatal and perinatal factors, growth and development assessments, and symptomatology.
Evaluation of a newborn with suspected congenital heart disease, follow-up of a child post-surgical repair, and assessment of exercise tolerance in older children.
Consideration of age-related changes in symptoms and the impact of growth on hemodynamics.
Family history of congenital heart defects, genetic testing results, and syndromic associations.
Genetic counseling for families with a history of congenital heart disease and evaluation of syndromic presentations.
Understanding the genetic basis of congenital heart defects and their implications for family planning.
Used for initial diagnosis and follow-up of SVASD.
Document the indication for the echocardiogram and findings.
Pediatric cardiology may require specific echocardiographic views.
Surgical intervention for symptomatic SVASD.
Detailed operative report and preoperative assessment.
Ensure documentation reflects the type of defect repaired.
Accurate coding of SVASD is crucial for appropriate management and treatment planning. It ensures that patients receive the necessary interventions and follow-up care, and it also impacts data collection for congenital heart disease research and resource allocation.
