Q20.9: Congenital malformation of cardiac chambers and connections, unspecified
Your heart did not develop properly before you were born.
The heart pumps blood through the body. Inside the heart are 4 chambers. There are 2 heart atria and 2 ventricles. Both heart atria and both ventricles are separated from each other by a partition.
A heart defect can alter blood flow in the heart. You may have various symptoms as a result. One may be short of breath, and feel weak or tired. The skin may appear bluish in color. The symptoms may begin shortly after birth or may develop at a later stage.
On medical documents, the ICD code is often appended by letters that indicate the diagnostic certainty or the affected side of the body.
- G: Confirmed diagnosis
- V: Tentative diagnosis
- Z: Condition after
- A: Excluded diagnosis
- L: Left
- R: Right
- B: Both sides
