ICD-10 Code D17.2 – Benign lipomatous neoplasm of skin and subcutaneous tissue of limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D17.2 – Benign lipomatous neoplasm of skin and subcutaneous tissue of limb
What it is
D17.2 identifies a benign fatty tumor located in the skin or subcutaneous tissue of an arm or leg. It is noncancerous and usually grows slowly.
Clinical signs
Typical findings include a soft, mobile, well-defined lump in a limb. Clinical features vary; refer to documentation for the exact site and whether the mass is superficial or subcutaneous.
When to use this code
Use D17.2 when the provider documents a benign lipomatous neoplasm of the skin or subcutaneous tissue in an upper or lower limb. This code fits a confirmed lipoma or similar benign fatty mass in that location. If the record only says “mass” or “lump,” check documentation before coding.
Do not use for
Do not use this code for malignant soft tissue tumors, liposarcoma, or lipomas in non-limb sites. If the lesion is not clearly documented as benign and limb-based, check documentation.
Coding tip
Confirm both benign behavior and limb location in the note before assigning D17.2.
