Information for Medical Professionals

Diagnostic Related Groups
The diagnosis code Q20.4 is grouped in the following Diagnostic Related Group(s) (MS-DRG V34.0)

  • 306 - CARDIAC CONGENITAL AND VALVULAR DISORDERS WITH MCC
  • 307 - CARDIAC CONGENITAL AND VALVULAR DISORDERS WITHOUT MCC

Convert to ICD-9 Additional informationCallout TooltipGeneral Equivalence Map
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

Present on Admission (POA) Additional informationCallout TooltipPresent on Admission
The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement.

The code Q20.4 is exempt from POA reporting.

Information for Patients


Congenital Heart Defects

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 birth defect. The defects can involve the walls of the heart, the valves of the heart, and the arteries and veins near the heart. They 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, or be blocked completely.

Doctors use a physical exam and special heart tests to diagnose congenital heart defects. They often find severe defects during pregnancy or soon after birth. Signs and symptoms of severe defects in newborns include

  • Rapid breathing
  • Cyanosis - a bluish tint to the skin, lips, and fingernails
  • Fatigue
  • Poor blood circulation

Many congenital heart defects cause few or no signs and symptoms. They are often not diagnosed until children are older.

Many children with congenital heart defects don't need treatment, but others do. Treatment can include medicines, catheter procedures, surgery, and heart transplants. The treatment depends on the type of the defect, how severe it is, and a child's age, size, and general health.
