Q24.8 is the authoritative medical code for Other specified congenital malformations of heart. This classification is used in medical billing and clinical recording to specify the clinical criteria for other specified congenital malformations of heart (ICD-10-CM Q24.8), ensuring healthcare documentation aligns with 2026 federal coding standards.
Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.
