ICD-10 Code B57.30 – Chagas’ disease with digestive system involvement, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B57.30 – Chagas’ disease with digestive system involvement, unspecified
What it is
B57.30 identifies Chagas’ disease affecting the digestive system, when the specific digestive manifestation is not documented. Use it for chronic Trypanosoma cruzi infection with gastrointestinal involvement that is not further specified.
Clinical signs
Clinical features vary; refer to documentation. Digestive involvement may present with dysphagia, constipation, abdominal distention, or other motility problems linked to Chagas’ disease.
When to use this code
Use this code when the record confirms Chagas’ disease and notes digestive system involvement, but does not name a more specific GI complication. It also fits when the provider documents digestive manifestations without enough detail for a more specific code. Verify whether cardiac or other organ involvement is also documented.
Do not use for
Do not use B57.30 if the chart specifies a more exact digestive manifestation, such as megacolon or megaesophagus. Also avoid it when Chagas’ disease is absent or when digestive symptoms are documented without confirmed Chagas’ infection.
Coding tip
Check the provider’s wording carefully; if the digestive complication is named, code the more specific option instead of this unspecified category.
