Dermatophytosis of hand

This code signifies a fungal infection affecting the skin of the hand, specifically caused by dermatophytes. This condition, commonly known as tinea manuum, presents with symptoms such as scaling, redness, itching, and sometimes blistering or cracking of the skin on the palms or back of the hand.

Utilize this code when documentation clearly indicates a dermatophyte infection localized to the hand. This diagnosis is typically supported by clinical examination findings consistent with tinea manuum, and may be confirmed by mycological studies such as KOH preparation or fungal culture.

• Differentiate from other non-fungal dermatoses of the hand, such as contact dermatitis or eczema, which require different codes.
• Ensure documentation specifies "hand" as the affected body part; if the infection is generalized or affects multiple sites, a more general dermatophytosis code or codes for other specific sites may be appropriate.
• Do not use for candidal infections of the hand, which are coded separately.
