ICD-10 Code B55.1 – Cutaneous leishmaniasis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B55.1 – Cutaneous leishmaniasis
What it is
Cutaneous leishmaniasis is a parasitic skin infection caused by Leishmania species. It usually produces localized skin lesions after exposure to infected sand flies.
Clinical signs
Typical findings include one or more slowly enlarging skin sores, often with raised borders and central ulceration. Clinical features vary; refer to documentation.
When to use this code
Use B55.1 when the record clearly documents cutaneous leishmaniasis, including skin-only infection confirmed or diagnosed by the clinician. Code it for localized lesions without evidence of visceral disease. If the note only says “leishmaniasis” or is unclear about the site, check documentation.
Do not use for
Do not use this code for visceral leishmaniasis or mucocutaneous disease. Do not assign it for a suspected exposure, screening, or unrelated skin ulcers.
Coding tip
Code the documented anatomic form of leishmaniasis, and verify whether the infection is cutaneous, mucocutaneous, or visceral before assigning B55.1.
