Erysipelothrix infection

This code represents an infection caused by bacteria of the genus Erysipelothrix, most commonly Erysipelothrix rhusiopathiae. This zoonotic infection typically manifests as erysipeloid, a localized skin infection characterized by a violaceous, raised lesion with a well-demarcated border, often on the hands or fingers. Systemic infections, though rare, can include endocarditis or septicemia.

Assign this code when documentation confirms a diagnosis of erysipelothrix infection, such as erysipeloid, based on clinical presentation, exposure history (e.g., handling raw fish, meat, or poultry), and/or laboratory confirmation. This code is appropriate for both localized cutaneous infections and more severe systemic manifestations.

• Ensure documentation specifies Erysipelothrix as the causative organism to differentiate from other bacterial skin infections like erysipelas (streptococcal).
• If a systemic infection such as endocarditis or septicemia is present, sequence the specific manifestation code first, followed by this code as a secondary diagnosis.
• Review the patient's occupational history for exposure risks, as this can support the diagnosis in the absence of definitive lab results.
