Other bulbus cordis anomalies and anomalies of cardiac septal closure

This code encompasses congenital malformations affecting the bulbus cordis, the embryonic precursor to the ventricles and outflow tracts, and structural defects in the cardiac septa that result in incomplete closure. These anomalies can lead to abnormal blood flow within the heart and great vessels, impacting cardiac function.

Use this code for documented congenital heart defects that involve the bulbus cordis, such as truncus arteriosus, or for unspecified or other specified septal closure defects not covered by more specific codes. Documentation should clearly indicate a congenital anomaly of these structures, often identified through echocardiography or cardiac catheterization.

• Avoid using this code if a more specific ICD-9-CM code exists for the documented septal defect (e.g., ventricular septal defect, atrial septal defect).
• Ensure the medical record explicitly states "bulbus cordis anomaly" or a specific septal closure defect not otherwise classified.
• Sequence this code as a primary diagnosis when it is the main reason for the encounter, or as a secondary diagnosis when it is a co-morbidity.
