Benign lipomatous neoplasm of skin, subcu of unsp limb

This code describes a non-cancerous fatty tumor originating in the skin or the tissue directly beneath it, located on an unspecified limb. These benign growths, known as lipomas, are typically soft, movable, and painless. They are composed of mature adipocytes.

Use this code when documentation specifies a benign lipoma of the skin or subcutaneous tissue on an arm or leg, but the specific limb (e.g., right arm, left leg) is not recorded. This code is appropriate when the physician's diagnosis explicitly states "lipoma" and indicates its superficial location on an unspecified extremity.

• Do not use this code if the lipoma is documented as malignant or of uncertain behavior; refer to codes in the C49 or D48 series.
• Avoid this code if the specific limb (e.g., right upper limb, left lower limb) is documented; instead, select a more specific code from the D17.2- subcategory.
• Ensure the documentation clearly states "benign lipomatous neoplasm" or "lipoma" to support this diagnosis.
