Cutaneous erysipeloid

This code identifies erysipeloid, a localized skin infection caused by Erysipelothrix rhusiopathiae. It typically presents as a well-demarcated, violaceous, edematous lesion with a raised border, often accompanied by burning, itching, and pain. The infection is usually self-limiting but can spread.

Use this code for documented cases of cutaneous erysipeloid, often acquired through contact with infected animal products (e.g., fish, poultry, meat) or soil. Documentation should clearly describe the characteristic skin lesion and may include a history of exposure or laboratory confirmation of Erysipelothrix rhusiopathiae.

• Differentiate from erysipelas (A46), which is caused by Streptococcus and has a more rapid onset and systemic symptoms.
• Ensure documentation specifies "cutaneous" to avoid confusion with systemic erysipeloid infections.
• Consider an external cause code (e.g., W56.01XA for contact with fish) if the source of infection is known and documented.
