ICD-10 Code B57.39 – Other digestive system involvement in Chagas’ disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B57.39 – Other digestive system involvement in Chagas’ disease
What it is
This code identifies Chagas’ disease with digestive tract involvement that does not fit the more specific esophageal or intestinal categories. Use it when documentation shows another digestive system manifestation linked to Trypanosoma cruzi infection.
Clinical signs
Clinical features vary; refer to documentation. Digestive involvement may include dysmotility, dilation, or other gastrointestinal abnormalities attributed to Chagas’ disease, but the record should support the specific digestive site involved.
When to use this code
Use B57.39 when the provider documents Chagas’ disease affecting the digestive system and the condition is not better described by a more specific code. It is appropriate for confirmed chronic sequelae or other recorded digestive involvement. If the note is vague, check documentation before assigning it.
Do not use for
Do not use this code for Chagas’ disease without digestive involvement, or when a more specific digestive manifestation is documented. If the record only mentions cardiac or neurologic disease, select the appropriate code instead.
Coding tip
Code the documented digestive manifestation first, and confirm that Chagas’ disease is explicitly linked in the record.
