Code Description

ICD-10 I51.0 is a billable code used to indicate a diagnosis of cardiac septal defect, acquired.

Key Diagnostic Point:

Cardiac septal defect, acquired, refers to a defect in the septum that separates the heart's chambers, which can lead to abnormal blood flow. This condition may arise from various causes, including heart surgery, myocardial infarction, or other cardiac conditions. Symptoms can vary widely, from none to significant heart failure, depending on the size of the defect and the degree of shunting. Diagnosis typically involves echocardiography, and treatment may include medical management or surgical intervention to repair the defect.
