Clinical Information
  • A congenital heart defect is a problem with the structure of the heart. It is present at birth. Congenital heart defects are the most common type of major birth defect.a baby's heart begins to develop shortly after conception. During development, structural defects can occur. These defects can involve the walls of the heart, the valves of the heart and the arteries and veins near the heart. Congenital heart defects can disrupt the normal flow of blood through the heart. The blood flow can
    • slow down
    • go in the wrong direction or to the wrong place
    • be blocked completely
    treatment for the defect can include medicines, surgery and other medical proceduresand heart transplants. The treatment depends on the type and severity of the defect and a child's age, size and general health. Today, many children born with complex heart defects grow to adulthood and lead productive lives.
  • Developmental abnormalities involving structures of the heart. These defects are present at birth but may be discovered later in life.
  • Imperfections or malformations of the heart, existing at birth
  • Imperfections or malformations of the heart, existing at, and usually before, birth regardless of their causation.

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 746.9 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
