Tinea imbricata

Tinea imbricata, also known as Tokelau, is a chronic, superficial fungal infection of the skin characterized by concentric, scaly rings that often overlap, creating a distinctive "imbricated" or "tiled" appearance. It is caused by specific dermatophyte species, primarily Trichophyton concentricum, and typically affects the trunk and limbs.

This code is appropriate for documenting a confirmed diagnosis of tinea imbricata based on clinical presentation and/or mycological studies (e.g., KOH preparation, fungal culture). It should be used when the provider explicitly identifies the characteristic imbricated pattern of the dermatophyte infection.

• Ensure documentation clearly specifies "imbricata" to differentiate from other forms of tinea corporis.
• Do not confuse with other dermatophytoses like tinea corporis (B35.4) or tinea manuum (B35.2) unless the imbricated pattern is specifically noted.
• Consider additional codes for any associated symptoms or complications, such as pruritus (L29.x) if documented.
