ICD-10 Code D17.0 – Benign lipomatous neoplasm of skin and subcutaneous tissue of head, face and neck (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D17.0 – Benign lipomatous neoplasm of skin and subcutaneous tissue of head, face and neck
What it is
This code identifies a benign fatty tumor located in the skin or subcutaneous tissue of the head, face, or neck. It indicates a noncancerous lipomatous growth in that specific anatomic site.
Clinical signs
These lesions are usually slow-growing, soft, and mobile under the skin. Clinical features vary; refer to documentation, especially if the mass is painless and well circumscribed.
When to use this code
Use D17.0 when the provider documents a benign lipoma or other benign lipomatous neoplasm in the head, face, or neck soft tissues. Apply it for confirmed site-specific documentation, including excised or observed lesions. Check documentation if the record only says “mass” or “cyst.”
Do not use for
Do not use this code for malignant tumors, unspecified soft tissue masses, or lipomas in other body sites. If the location is not documented as head, face, or neck, check documentation.
Coding tip
Code the exact anatomic site from the provider note, because D17.0 is location-specific.
