B35.9
ICD-10-CMThis code represents a fungal infection of the skin, hair, or nails, commonly known as ringworm, when the specific type or location of the dermatophyte infection is not documented. It indicates a superficial mycosis caused by dermatophytes, without further specification of the causative organism or affected body site.
Use this code when the medical record clearly indicates a dermatophytosis but lacks details regarding the specific anatomical site (e.g., tinea pedis, tinea corporis) or the identified fungal species. This code is appropriate when the provider's documentation states "dermatophytosis, unspecified" or similar terminology without further elaboration.
