ICD-10 Code B57.2 – Chagas’ Disease (Chronic) with Heart Involvement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B57.2 – Chagas’ disease (chronic) with heart involvement
What it is
B57.2 identifies chronic Chagas disease when the heart is affected. Use it for documented Trypanosoma cruzi infection with cardiac involvement, such as chronic Chagas cardiomyopathy.
Clinical signs
Typical findings include conduction abnormalities, arrhythmias, cardiomyopathy, heart failure, or thromboembolic complications. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states chronic Chagas disease with cardiac involvement, or when the clinician documents Chagas cardiomyopathy. It is appropriate for encounters focused on established heart disease due to prior T. cruzi infection. Check documentation if the heart involvement is not clearly linked to Chagas disease.
Do not use for
Do not use it for acute Chagas disease or for Chagas infection without heart involvement. Do not assign it when cardiac findings are present but Chagas disease is not documented.
Coding tip
Confirm the note links the cardiac condition to chronic Chagas disease before assigning B57.2.
