ICD-10 Code D17.39 – Benign lipomatous neoplasm of skin and subcutaneous tissue of other sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D17.39 – Benign lipomatous neoplasm of skin and subcutaneous tissue of other sites
What it is
This code identifies a benign lipoma or similar fatty tumor located in the skin or subcutaneous tissue of sites other than the specifically listed body areas. It means the growth is noncancerous and arises from adipose tissue.
Clinical signs
Typical findings include a soft, usually movable, slow-growing lump under the skin. Clinical features vary; refer to documentation, especially when the site is not one of the more specific coded locations.
When to use this code
Use D17.39 when the provider documents a benign lipomatous neoplasm in the skin or subcutaneous tissue and the lesion is in an “other site” not captured by a more specific code. Code it when pathology, imaging, or clinical assessment supports a benign fatty tumor and the anatomic site is clearly documented.
If the note only says “lipoma” without a more specific location, confirm the site before assigning this code. You should also use this code when the lesion is described as a benign lipomatous mass of the skin or subcutaneous tissue at an unspecified non-listed site.
Do not use for
Do not use this code for lipomas in sites with a more specific ICD-10-CM option, or for malignant soft tissue tumors. Check documentation if the lesion is not clearly benign or if the anatomic site is better specified elsewhere.
Coding tip
Match the documented site carefully; if a more specific location is named, choose that code instead of D17.39.
