Unspecified defect of septal closure

This code represents a congenital heart defect characterized by an opening in the septum (the wall dividing the heart's chambers) where the specific type or location of the defect is not documented. It indicates a structural abnormality present at birth that allows abnormal blood flow between the heart chambers.

Use this code when medical record documentation confirms a septal defect but lacks further specificity regarding its type (e.g., atrial, ventricular, or atrioventricular) or precise anatomical location. This code is appropriate when the physician's diagnosis is simply "septal defect" without additional detail.

• Avoid using this code if more specific documentation is available (e.g., ventricular septal defect, atrial septal defect).
• Query the provider for greater specificity if possible, as more precise codes exist and offer better data for patient care and research.
• This code should be sequenced as a primary diagnosis when the septal defect is the reason for the encounter or as a secondary diagnosis if it's an co-existing condition.
