ICD-10 Code A01.02 – Typhoid fever with heart involvement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A01.02 – Typhoid fever with heart involvement
What it is
This code identifies typhoid fever caused by Salmonella Typhi with documented heart involvement. Use it when the record links the infection to cardiac complications or cardiac disease.
Clinical signs
Clinical features vary; refer to documentation. Heart involvement may be described as myocarditis, pericarditis, endocarditis, or other cardiac manifestations occurring with typhoid fever.
When to use this code
Use A01.02 when the provider clearly documents typhoid fever and specifies heart involvement. It is appropriate for inpatient or outpatient records that connect the infection to a cardiac complication. If the chart only says typhoid fever without cardiac involvement, do not assign this code.
Do not use for
Do not use this code for typhoid fever without heart involvement, or for nonspecific febrile illness where typhoid is not confirmed. Check documentation if the cardiac finding is unrelated or not clearly linked to the infection.
Coding tip
Verify that both typhoid fever and the heart complication are documented together before assigning A01.02.
