Pyoderma vegetans

This code represents a rare, chronic, and severe form of pyoderma characterized by vegetative, verrucous, and pustular lesions, often with surrounding inflammation. It typically affects intertriginous areas, the scalp, or the face, and can be associated with inflammatory bowel disease or other systemic conditions.

Use this code when documentation clearly specifies "pyoderma vegetans" as the patient's diagnosis. This diagnosis is typically made based on clinical presentation and confirmed by biopsy showing pseudoepitheliomatous hyperplasia and intraepidermal abscesses. Ensure the physician's notes differentiate this specific type of pyoderma from other forms.

• Do not code with L88 (pyoderma gangrenosum) or L08.0 (pyoderma NOS) due to Excludes1 notes.
• Always review documentation to confirm the specific type of pyoderma to avoid miscoding.
• Consider coding any underlying systemic conditions, such as inflammatory bowel disease, as secondary diagnoses.
