The ICD-10 code for Chagas' disease ranges from B57.0 for acute cases with heart involvement to B57.5 for chronic cases involving other organs such as the skin. Synonyms like "Acute Chagas' disease with heart involvement" associate with B57.0, while "Chagoma" and "Trypanosomiasis affecting skin" relate to B57.1 and B57.5. Digestive complications, including "Megaesophagus" and "Megacolon", are captured under B57.31 and B57.32. Nervous system manifestations like "Meningitis due to Chagas disease" and "Meningoencephalitis" correspond to B57.41 and B57.42, respectively.
