ICD-10 Code D17 – Benign lipomatous neoplasm (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D17 – Benign lipomatous neoplasm
What it is
D17 identifies a noncancerous tumor made of fat tissue, also called a lipoma or benign lipomatous neoplasm. It indicates a benign growth rather than a malignant soft tissue tumor.
Clinical signs
These lesions are often slow-growing, soft, and mobile under the skin. Clinical features vary; refer to documentation, especially when the site, size, or depth is described.
When to use this code
Use D17 when the provider documents a benign lipomatous neoplasm or lipoma and does not specify a more exact site-specific code. It may also apply when pathology or imaging confirms a benign fatty mass. Check documentation for the anatomic location and any laterality details.
Do not use for
Do not use D17 for malignant liposarcoma or for nonspecific soft tissue masses without documentation of a benign lipomatous neoplasm. If the record does not clearly support the diagnosis, check documentation.
Coding tip
Capture the exact location whenever it is documented, because many benign lipomatous neoplasms have more specific ICD-10 codes.
