Dermatophytosis of the body

This code signifies a superficial fungal infection affecting the non-hairy skin of the trunk, limbs, or face, commonly known as tinea corporis. It is caused by dermatophytes, which thrive on keratin and present with characteristic annular, erythematous, and scaly lesions.

Use this code when documentation specifies a dermatophyte infection localized to the body, excluding the scalp, nails, feet, or groin. This diagnosis is typically supported by physical examination findings and may be confirmed by KOH prep or fungal culture.

• Differentiate from other tinea infections; ensure the documentation specifies "body" or "corporis."
• Do not use for tinea capitis, tinea pedis, tinea cruris, or onychomycosis, which have distinct codes.
• Consider an additional code for the causative organism if identified and clinically significant.
