ICD-10 Code D17.30 – Benign lipomatous neoplasm of skin and subcutaneous tissue of unspecified sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D17.30 – Benign lipomatous neoplasm of skin and subcutaneous tissue of unspecified sites
What it is
This code identifies a benign fatty tumor in the skin or subcutaneous tissue when the site is not specified. It indicates a noncancerous lipomatous growth rather than a malignant soft tissue mass.
Clinical signs
These lesions are usually soft, mobile, and slowly growing beneath the skin. Clinical features vary; refer to documentation for the exact location and whether the mass is painless or symptomatic.
When to use this code
Use this code when the provider documents a benign lipomatous neoplasm of the skin or subcutaneous tissue and does not name a specific anatomic site. It also fits when the record clearly supports a benign fatty lesion but the location is unspecified. Check documentation if another lipoma site is recorded.
Do not use for
Do not use this code for malignant tumors, liposarcoma, or other non-benign soft tissue masses. Do not assign it when the provider documents a specific site that has a more precise code.
Coding tip
Confirm both benign nature and unspecified site in the note before assigning D17.30.
