ICD-10 code for Chagas' disease

The ICD-10-CM code for Chagas' disease is B57.2 (Chagas' disease (chronic) with heart involvement). The official index lists 16 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on B57.2.

Within B57 (Chagas' disease), B57.2 is specifically for Chagas' disease (chronic) with heart involvement. Related codes cover acute Chagas' disease with heart involvement (B57.0), acute Chagas' disease without heart involvement (B57.1), (chronic) with digestive system involvement (B57.3), (chronic) with nervous system involvement (B57.4) and (chronic) with other organ involvement (B57.5).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 314 (Other Circulatory System Diagnoses with MCC, relative weight 2.0873), DRG 315 (Other Circulatory System Diagnoses with CC, relative weight 0.9508) and DRG 316 (Other Circulatory System Diagnoses without CC/MCC, relative weight 0.6677), in MDC 05 (Diseases and Disorders of the Circulatory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
