I25.3 ICD 2026 Code: Aneurysm of heart

I25.3 is the authoritative medical code for Aneurysm of heart. This classification is used in medical billing and clinical recording to specify the clinical criteria for aneurysm of heart (ICD-10-CM I25.3), ensuring healthcare documentation aligns with 2026 federal coding standards.

Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.
