Mucocutaneous leishmaniasis

This code represents a chronic parasitic infection caused by Leishmania species, specifically affecting the skin and mucous membranes. It is characterized by destructive lesions, particularly in the nasopharyngeal region, which can lead to severe disfigurement and functional impairment.

Use this code when documentation confirms a diagnosis of mucocutaneous leishmaniasis, often presenting with ulcerative or nodular lesions on the face, mouth, or nose. Supporting documentation should include laboratory confirmation of Leishmania parasites or characteristic histopathological findings in affected tissues.

• Differentiate from cutaneous leishmaniasis (B55.1) which primarily affects the skin without mucosal involvement.
• Consider additional codes for any associated complications, such as secondary bacterial infections or respiratory compromise.
• Ensure the medical record clearly specifies the mucocutaneous form to avoid confusion with other leishmaniasis types.
