B43.8
ICD-10-CMThis code represents various less common or atypical presentations of chromomycosis, a chronic fungal infection of the skin and subcutaneous tissue. It is caused by dematiaceous fungi and typically manifests as verrucous nodules or plaques, often on the extremities. This category is used when the specific type of chromomycosis does not fit into other, more defined categories.
Use this code when documentation confirms a diagnosis of chromomycosis, but the specific form or causative organism is not otherwise classified. This applies to cases where the clinical presentation or fungal identification points to chromomycosis, but not to a specific variant like phaeohyphomycosis or other specified forms. Documentation should clearly state "other forms of chromomycosis" or describe a chromomycosis not fitting other specific codes.
