Atrioventricular septal defect
ICD-10 Q21.2 is a billable code used to indicate a diagnosis of atrioventricular septal defect.
Atrioventricular septal defect (AVSD) is a congenital heart defect characterized by a combination of atrial septal defect (ASD) and ventricular septal defect (VSD), along with a single common atrioventricular valve instead of separate mitral and tricuspid valves. This condition results in abnormal blood flow between the heart chambers, leading to increased pulmonary blood flow and potential heart failure if left untreated. AVSD can occur as an isolated defect or as part of a genetic syndrome, such as Down syndrome. Symptoms may include difficulty breathing, poor feeding, and failure to thrive in infants. Diagnosis is typically made through echocardiography, which reveals the structural abnormalities. Surgical intervention is often required to repair the defect and improve cardiac function, usually performed in early childhood. Long-term follow-up is essential to monitor for potential complications, including arrhythmias and valve dysfunction.
Detailed clinical notes on symptoms, diagnostic imaging results, and treatment plans are essential. Documentation should include growth parameters and developmental milestones.
Infants presenting with respiratory distress, failure to thrive, or heart murmurs during routine examinations.
Consideration of the patient's age and weight is crucial for determining the timing of surgical intervention.
Genetic testing results, family history of congenital defects, and any syndromic associations should be documented.
Patients with AVSD being evaluated for genetic syndromes, such as Down syndrome, or those with a family history of congenital heart disease.
Understanding the genetic implications and counseling families about recurrence risks is vital.
Used during surgical intervention for AVSD repair.
Operative report detailing the procedure performed and any complications.
Pediatric cardiology and cardiothoracic surgery documentation must align.
Accurate coding of AVSD is crucial for appropriate reimbursement, tracking of congenital heart defects, and ensuring that patients receive the necessary follow-up care and interventions.
