ICD-10 Code D17.79 – Benign lipomatous neoplasm of other sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D17.79 – Benign lipomatous neoplasm of other sites
What it is
This code identifies a benign, fatty tumor in a location other than the more specific lipoma sites listed elsewhere. Use it when documentation clearly states a benign lipomatous neoplasm of another site.
Clinical signs
These lesions are often slow-growing, soft, and usually painless. Clinical features vary; refer to documentation, imaging, or pathology when the site or nature of the mass is being confirmed.
When to use this code
Use D17.79 when the provider documents a benign lipomatous neoplasm at an unspecified “other” site and no more specific code applies. It may also fit after excision or biopsy confirms a benign lipomatous tumor in that location. Do not guess the site from incomplete notes; check documentation.
Do not use for
Do not use this code for malignant soft tissue tumors, liposarcoma, or lesions documented as lipoma at a specific anatomic site with a more precise code. If the diagnosis is uncertain, check documentation.
Coding tip
Code the most specific documented site first; reserve D17.79 only when the record supports “other sites” and no better option is available.
