ICD-10 Code B55.2 – Mucocutaneous leishmaniasis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B55.2 – Mucocutaneous leishmaniasis
What it is
Mucocutaneous leishmaniasis is a parasitic infection that affects the skin and mucous membranes, especially the nose, mouth, or throat. Use this code when documentation identifies this specific form of leishmaniasis.
Clinical signs
Typical findings include skin lesions with mucosal involvement, such as nasal congestion, ulceration, or destructive changes in the nose or mouth. Clinical features vary; refer to documentation.
When to use this code
Use B55.2 when the provider documents mucocutaneous leishmaniasis, including cases described as mucosal or mucocutaneous involvement from Leishmania infection. Code it from confirmed diagnoses in the record, not from exposure alone. If the note is vague, check documentation.
Do not use for
Do not use this code for cutaneous leishmaniasis without mucosal involvement or for visceral leishmaniasis. If the record does not clearly specify mucocutaneous disease, check documentation.
Coding tip
Verify that mucosal involvement is documented; that distinction supports B55.2.
