Dermatophytosis of groin and perianal area

This code represents a superficial fungal infection affecting the skin folds of the groin and the perianal region. It is commonly known as tinea cruris or "jock itch," caused by dermatophytes. The infection typically presents with an erythematous, pruritic rash, often with scaling and a well-demarcated border.

Use this code when documentation clearly indicates a dermatophyte infection specifically localized to the groin or perianal area. This includes diagnoses such as tinea cruris. Supporting documentation should describe the characteristic rash, location, and may include mycological findings if available.

• Differentiate from candidiasis (e.g., 112.3), which is a yeast infection and often presents differently.
• Ensure the documentation specifies "dermatophytosis" or "tinea" and the exact anatomical location (groin/perianal).
• Do not use for fungal infections of other body sites; refer to specific codes for tinea pedis, tinea corporis, etc.
