Candidiasis of skin and nails

This code signifies a fungal infection of the skin and/or nails caused by Candida species, commonly Candida albicans. It presents with various manifestations such as intertrigo, diaper rash, paronychia, or onychomycosis, characterized by erythema, scaling, pustules, or nail dystrophy.

Apply this code when documentation clearly indicates a candidal infection affecting the epidermis, dermis, or nail plate. This includes conditions like cutaneous candidiasis, candidal intertrigo, or candidal onychomycosis. Supporting documentation should specify Candida as the causative organism, often confirmed by KOH prep or fungal culture.

• Differentiate from other fungal skin infections (e.g., tinea) which have distinct ICD-9-CM codes.
• Ensure the documentation specifies Candida as the etiology; otherwise, a more general fungal infection code may be appropriate.
• Consider an additional code for any associated systemic candidiasis if present and documented.
