Impetigo

This code identifies a superficial bacterial skin infection characterized by vesicles, pustules, and honey-colored crusts, primarily caused by Staphylococcus aureus or Streptococcus pyogenes. It is highly contagious and commonly affects children, often appearing on the face, neck, and hands.

Assign this code when documentation clearly indicates a diagnosis of impetigo, regardless of the specific bacterial etiology. This code is appropriate for both bullous and non-bullous forms of the infection. Supporting documentation would include physician notes detailing the characteristic skin lesions and a confirmed diagnosis.

• Do not use this code for other bacterial skin infections like folliculitis or cellulitis; these have distinct codes.
• If a secondary infection or complication is present, such as cellulitis originating from the impetigo, code the impetigo first, followed by the complication.
• Ensure the documentation specifies impetigo and not a general "skin infection" to support this specific diagnosis.
