Other digestive system involvement in Chagas' disease

This code signifies digestive system manifestations of Chagas disease, excluding those specifically affecting the esophagus (B57.31) or colon (B57.32). It encompasses other gastrointestinal complications such as gastroparesis, chronic constipation not meeting megacolon criteria, or other dysmotility issues directly attributable to Trypanosoma cruzi infection. These complications arise from parasitic damage to the enteric nervous system.

Use this code when documentation specifies digestive involvement in Chagas disease that is not explicitly esophageal or colonic. This includes conditions like chronic chagasic gastritis, small bowel dysmotility, or other unspecified gastrointestinal dysfunction confirmed to be a sequela of Chagas. Supporting documentation should clearly link the digestive symptoms or findings to a confirmed diagnosis of Chagas disease.

• Always sequence a code for the underlying Chagas disease (B57.x) first, if not already established.
• Distinguish carefully between esophageal (B57.31) and colonic (B57.32) involvement to ensure correct subcategory assignment.
• Ensure documentation explicitly states the digestive system involvement is due to Chagas disease, rather than other etiologies.
