Erysipelas

This code represents an acute, superficial bacterial skin infection characterized by well-demarcated, erythematous, edematous plaques with a raised border. It primarily affects the dermis and superficial lymphatic vessels, commonly presenting on the face or lower extremities. The causative agent is typically Streptococcus pyogenes.

Use this code for documented cases of erysipelas, excluding those specifically related to the postpartum or puerperal period. Documentation should clearly indicate the diagnosis of erysipelas, often supported by clinical presentation, physical examination findings, and sometimes laboratory results. This code is appropriate for both initial and subsequent encounters for this condition.

• Ensure documentation explicitly states "erysipelas" and not a more generalized cellulitis, which is a deeper infection.
• Carefully review the patient's history to rule out postpartum or puerperal onset, as this requires a different code (O86.89).
• Consider coding any associated complications, such as bacteremia or sepsis, if documented and supported.
