    ICD-10-CM Code For Leishmaniasis: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group B55 includes diagnoses for leishmaniasis, covering cutaneous, mucocutaneous, visceral (kala-azar) forms, and sequelae resulting from Leishmania infection. These ICD-10-CM diagnosis codes are used to document clinical presentations such as localized skin ulcers, mucosal destruction, systemic febrile illness with hepatosplenomegaly, or post-treatment complications, capturing disease severity and organ involvement. Accurate coding within the ICD-10-CM B55 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM B55: Leishmaniasis Overview

    The ICD-10-CM B55 group represents infections caused by Leishmania species, protozoal parasites transmitted by phlebotomine sand flies that can affect the skin, mucous membranes, and internal organs. These diagnoses target cutaneous, mucocutaneous, and visceral forms of leishmaniasis and related sequelae. Accurate coding matters for reimbursement because it supports clear documentation of disease severity, organ system involvement, and treatment complexity, which affect claim adjudication and clinical records.
