ICD-10 Code D17.23 – Benign lipomatous neoplasm of skin and subcutaneous tissue of right leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D17.23 – Benign lipomatous neoplasm of skin and subcutaneous tissue of right leg
What it is
This code identifies a benign fatty tumor located in the skin or subcutaneous tissue of the right leg. It indicates a noncancerous lipomatous growth, not a malignant neoplasm.
Clinical signs
Typical findings include a soft, usually movable, painless mass beneath the skin. Clinical features vary; refer to documentation, especially when the lesion is described as lipoma or benign fatty tumor.
When to use this code
Use D17.23 when the provider documents a benign lipomatous neoplasm specifically in the skin or subcutaneous tissue of the right leg. Apply it when the lesion is localized to the right lower limb and there is no evidence of malignancy.
Check documentation if the note only says “lipoma” without site, or if the mass is in a different leg location. You need laterality and anatomic site to support this code.
Do not use for
Do not use this code for malignant soft tissue tumors or for lipomas in another body site. Do not assume the right leg when the documentation is vague or lists a different extremity.
Coding tip
Verify both laterality and tissue depth in the record before assigning D17.23.
