Partial atrioventricular septal defect
ICD-10 Q21.21 is a billable code used to indicate a diagnosis of partial atrioventricular septal defect.
Partial atrioventricular septal defect (AVSD) is a congenital heart defect characterized by a combination of atrial septal defect (ASD) and ventricular septal defect (VSD) with a single common atrioventricular valve. This condition results in abnormal blood flow between the heart chambers, leading to increased pulmonary blood flow and potential heart failure if left untreated. Patients may present with symptoms such as cyanosis, fatigue, and difficulty breathing, particularly during exertion. Diagnosis is typically made through echocardiography, which reveals the structural anomalies of the heart. Management often involves surgical intervention to repair the septal defects and reconstruct the atrioventricular valve, aiming to restore normal hemodynamics and improve the patient's quality of life. Long-term follow-up is essential to monitor for potential complications, including arrhythmias and valve dysfunction.
Pediatric documentation should include growth parameters, developmental milestones, and specific symptoms related to heart function.
Common scenarios include routine check-ups for children with known congenital heart defects, pre-operative assessments, and post-operative follow-ups.
Consideration must be given to the child's age, growth patterns, and any developmental delays that may arise from the condition.
Genetic documentation should include family history of congenital heart defects and any chromosomal abnormalities identified through testing.
Scenarios may involve genetic counseling for families with a history of congenital heart defects or syndromic presentations.
Genetic testing results should be clearly documented to support any associated syndromes or chromosomal abnormalities.
Used during surgical intervention for partial AVSD.
Operative report detailing the procedure and findings.
Pediatric cardiology and cardiothoracic surgery documentation must be precise.
Partial AVSD involves a single atrioventricular valve and is associated with an ASD and VSD, while complete AVSD has a more complex structure with two atrioventricular valves and is often associated with additional anomalies.
