Ben lipomatous neoplm of skin, subcu of head, face and neck

This code signifies a non-cancerous fatty tumor originating in the skin or subcutaneous tissue specifically located on the head, face, or neck. These are typically slow-growing, soft, movable masses composed of mature adipocytes.

Apply this code for documented diagnoses of benign lipomas or other benign lipomatous neoplasms affecting the integumentary system of the head, face, or neck. Supporting documentation includes physician notes confirming the benign nature and precise anatomical location.

• Ensure the documentation explicitly states "benign" and specifies the head, face, or neck as the anatomical site.
• Do not use for lipomas of internal organs or other body regions; site-specific codes exist for those.
• Distinguish from malignant liposarcomas, which are coded to the C49 series.
