ICD-10-CM Code For Congenital Malformations Of Cardiac Septa: Group Overview
The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group Q21 includes congenital malformations of cardiac septa such as atrial septal defects, ventricular septal defects, and atrioventricular septal defects that disrupt normal intracardiac septation. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving structural septal abnormalities, associated hemodynamic impact, and any related complications or syndromic associations. Accurate coding within the ICD-10-CM Q21 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM Q21: Congenital Malformations Of Cardiac Septa Overview
The ICD-10-CM Q21 group covers congenital defects of the heart septa, including atrial septal defects, ventricular septal defects, and atrioventricular septal defects that impair normal intracardiac blood flow. These conditions affect the structure of the heart within the circulatory system and often present in neonates, infants, or detected later in life. Accurate coding matters for documenting clinical complexity and supporting appropriate reimbursement and care coordination.
