Bullous impetigo

This code represents a bacterial skin infection characterized by the formation of fluid-filled blisters (bullae) on the skin. It is a more severe form of impetigo, typically caused by Staphylococcus aureus, and often affects infants and young children. The bullae are typically fragile and rupture easily, leaving behind a moist, red base that may crust over.

Use this code when documentation clearly specifies "bullous impetigo" as the patient's diagnosis. This diagnosis is typically made clinically based on the characteristic blistering lesions. Supporting documentation should include details about the appearance of the lesions, their location, and any associated symptoms.

• Differentiate from non-bullous impetigo, which presents with smaller vesicles and honey-colored crusts.
• Do not confuse with other blistering skin conditions like pemphigus or bullous pemphigoid, which have different etiologies and clinical presentations.
• Consider an additional code for the causative organism (e.g., Staphylococcus aureus) if identified and documented.
