Frequently Asked Questions
The ICD-10 code range Q20-Q28 includes common congenital heart defects such as atrial septal defect, ventricular septal defect, tetralogy of Fallot, and patent ductus arteriosus. These conditions affect the structure and function of the heart and circulatory system from birth.
Congenital malformations of the circulatory system are typically diagnosed using imaging techniques such as echocardiography, MRI, or CT scans. These tools help visualize the heart's structure and identify defects early, often before or shortly after birth.
Treatment options for congenital heart defects in infants may include medications, catheter-based procedures, or surgery, depending on the severity and type of defect. Early intervention is crucial for managing symptoms and improving outcomes.
