Tinea corporis

This code represents a dermatophyte infection affecting the trunk, limbs, or face, excluding the scalp, groin, hands, and feet. It is commonly known as ringworm of the body, characterized by annular lesions with raised, erythematous borders and central clearing.

Use this code when documentation confirms a fungal infection of the skin on the body, excluding specific anatomical sites covered by other tinea codes. Supporting documentation typically includes a physician's diagnosis of tinea corporis, often based on clinical appearance or positive fungal culture/KOH prep.

• Differentiate from other tinea infections; ensure the affected body area is not scalp (tinea capitis), groin (tinea cruris), hand (tinea manuum), or foot (tinea pedis).
• Do not use for candidiasis or other non-dermatophyte fungal skin infections.
• Consider an additional code for the causative organism if identified and documented (e.g., B49 for unspecified mycosis if the specific dermatophyte is not known).
