Chagas' disease (chronic) with other organ involvement

This code signifies chronic Chagas disease where the parasitic infection has progressed beyond the acute phase and is affecting multiple organ systems, excluding the heart or digestive tract as primary manifestations. It indicates systemic involvement of Trypanosoma cruzi in organs such as the central nervous system, peripheral nervous system, or other non-cardiac/non-gastrointestinal sites.

Apply this code when documentation specifies chronic Chagas disease with systemic manifestations impacting organs other than the heart or GI tract. This would include neurological complications like meningoencephalitis or peripheral neuropathy, or other less common organ involvements. Supporting documentation should clearly state the chronic nature of the infection and the specific "other" organ system affected.

• Ensure documentation explicitly states "chronic" Chagas disease and specifies organ involvement other than cardiac or digestive.
• Do not use this code if the primary organ involvement is cardiac (B57.2) or digestive (B57.3).
• Code additional specific manifestations of the other organ involvement (e.g., G05.2 for meningoencephalitis in parasitic disease) as secondary diagnoses.
