ICD-10 Code D17.24 – Benign lipomatous neoplasm of skin and subcutaneous tissue of left leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D17.24 – Benign lipomatous neoplasm of skin and subcutaneous tissue of left leg
What it is
This code identifies a benign fatty tumor located in the skin or subcutaneous tissue of the left leg. It is noncancerous, but you should confirm the documented site and laterality.
Clinical signs
Typical findings include a soft, mobile, slow-growing mass beneath the skin. Clinical features vary; refer to documentation for whether imaging or pathology supported the diagnosis.
When to use this code
Use D17.24 when the record clearly states a benign lipomatous neoplasm in the left leg, including the skin or subcutaneous tissue. Apply it when the provider documents the lesion as a lipoma or similar benign fatty tumor at that specific site. If laterality or anatomic depth is unclear, check documentation before coding.
Do not use for
Do not use this code for malignant soft tissue tumors, unspecified lipomas without left-leg documentation, or lesions in a different body site. Check documentation if the mass is not clearly described as benign.
Coding tip
Code only after confirming both benign nature and left-leg location in the provider note.
