Congenital subaortic stenosis
ICD-10 Q24.4 is a billable code used to indicate a diagnosis of congenital subaortic stenosis.
Congenital subaortic stenosis is a type of congenital heart defect characterized by a narrowing of the outflow tract just below the aortic valve. This condition can lead to obstruction of blood flow from the left ventricle to the aorta, resulting in increased pressure within the left ventricle and potential heart failure if left untreated. It is often associated with other congenital heart defects, such as ventricular septal defects or aortic coarctation. Symptoms may include fatigue, difficulty breathing, and poor feeding in infants. Diagnosis is typically made through echocardiography, which can visualize the narrowing and assess the severity of the obstruction. Treatment may involve surgical intervention to relieve the obstruction, particularly in symptomatic patients. Long-term follow-up is essential to monitor for potential complications, including left ventricular hypertrophy and arrhythmias. The condition can occur in isolation or as part of syndromic presentations, necessitating a thorough genetic evaluation in some cases.
Pediatric documentation should include growth parameters, feeding difficulties, and developmental milestones, as well as detailed cardiac assessments.
Common scenarios include infants presenting with failure to thrive, respiratory distress, or heart murmurs detected during routine examinations.
Coders should be aware of the need for comprehensive documentation of any associated congenital anomalies and the patient's clinical course.
Genetic documentation should include family history, results of genetic testing, and any syndromic associations.
Scenarios may involve genetic counseling for families with a history of congenital heart defects or syndromes associated with subaortic stenosis.
Coders should ensure that genetic evaluations are documented, especially if there is a suspicion of a chromosomal abnormality.
Used in cases of significant subaortic stenosis requiring intervention.
Document indication for procedure, pre-operative assessments, and post-operative care.
Ensure cardiology and surgical notes are aligned for accurate coding.
Common symptoms include fatigue, difficulty breathing, poor feeding in infants, and exercise intolerance in older children. Symptoms can vary based on the severity of the stenosis.
