Granuloma faciale [eosinophilic granuloma of skin]

This code represents a rare, chronic inflammatory skin condition characterized by single or multiple reddish-brown to violaceous papules, plaques, or nodules, typically located on the face. Histologically, it involves a dense dermal infiltrate of lymphocytes, plasma cells, histiocytes, and eosinophils, often with vasculitis. It is a benign condition, primarily of cosmetic concern.

Assign this code when documentation explicitly states a diagnosis of granuloma faciale. This diagnosis is typically made clinically and confirmed by skin biopsy showing characteristic histopathological features. It is appropriate for both initial diagnosis and subsequent encounters for management of this specific dermatological condition.

• Ensure the documentation clearly distinguishes granuloma faciale from other facial dermatoses or granulomatous conditions.
• Do not confuse with other forms of eosinophilic granuloma, such as those affecting bone (e.g., Langerhans cell histiocytosis), as this code is specific to the skin.
• Consider any associated symptoms or complications for additional coding, but this code alone describes the primary skin condition.
