African trypanosomiasis, unspecified

This code represents African sleeping sickness, a parasitic disease caused by Trypanosoma brucei transmitted by the tsetse fly. It encompasses both the early (hemolymphatic) and late (meningoencephalitic) stages of the disease when the specific type of African trypanosomiasis is not documented.

Use this code when documentation confirms a diagnosis of African trypanosomiasis but does not specify whether it is East African (due to T. b. rhodesiense) or West African (due to T. b. gambiense). This code is appropriate when the physician's diagnosis is simply "African trypanosomiasis" without further detail.

• Avoid using this code if the specific type of African trypanosomiasis (East or West African) is documented; instead, use the more specific codes.
• Ensure documentation clearly states "African trypanosomiasis" or "sleeping sickness" to support this diagnosis.
• Do not confuse with American trypanosomiasis (Chagas disease), which is coded elsewhere.
