Foreign body granuloma of skin and subcutaneous tissue

This code represents an inflammatory reaction in the skin or subcutaneous tissue characterized by the formation of granulomas, caused by the presence of a foreign substance. This reaction is a delayed hypersensitivity response to material introduced into the body, often resulting in a persistent nodule or lesion.

Use this code when documentation clearly indicates a granulomatous reaction in the skin or subcutaneous tissue due to a foreign body. This includes reactions to sutures, injected substances (e.g., silicone, fillers), splinters, or other non-biologic materials. The physician's notes should specify the presence of a foreign body and the resulting granuloma.

• Ensure the documentation specifies the skin or subcutaneous tissue as the affected site; granulomas in other tissues have different codes.
• Do not use this code for granulomas due to infectious agents or autoimmune conditions; these have specific codes.
• Consider an external cause code (E-code) if the foreign body introduction was accidental (e.g., splinter, glass).
