Pyoderma

This code represents a bacterial skin infection characterized by pus-filled lesions. It typically involves the superficial layers of the skin, often presenting as impetigo, folliculitis, or ecthyma. The infection is usually caused by Staphylococcus aureus or Streptococcus pyogenes.

Use this code when documentation specifies a general diagnosis of pyoderma without further specificity regarding the type or underlying cause. This applies to cases where the physician has diagnosed a bacterial skin infection with pus formation, but has not identified it as a specific condition like impetigo or cellulitis.

• Ensure the documentation clearly indicates a bacterial skin infection with pus.
• Do not use this code if a more specific diagnosis, such as impetigo (L00) or cellulitis (L03.-), is documented.
• Remember the Excludes1 notes: never code this with pyoderma gangrenosum (L88) or pyoderma vegetans (L08.81).
