Erythrasma

This code represents erythrasma, a superficial bacterial skin infection caused by Corynebacterium minutissimum. It typically presents as well-demarcated, reddish-brown patches with fine scales, often found in intertriginous areas such as the groin, axillae, and toe webs.

Use this code when documentation confirms a diagnosis of erythrasma, often identified by its characteristic coral-red fluorescence under Wood's lamp examination. This code is appropriate for both initial and subsequent encounters related to the management of this specific bacterial skin infection.

• Ensure documentation specifies erythrasma and not other similar-appearing fungal or inflammatory skin conditions.
• Do not confuse with tinea cruris or intertrigo, which are distinct conditions requiring different codes.
• Consider additional codes for any associated symptoms or complications, if documented.
