2026 ICD-10-CM Diagnosis Code D17.22 – Benign lipomatous neoplasm of skin and subcutaneous tissue of left arm
What it is
This code identifies a benign fatty tumor located in the skin or subcutaneous tissue of the left arm. It indicates a noncancerous lipomatous growth in that specific site.
Clinical signs
Typical findings include a soft, usually mobile, slow-growing mass beneath the skin. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a benign lipoma or other benign lipomatous neoplasm in the skin or subcutaneous tissue of the left arm. It is appropriate when the site is clearly stated as left arm and the lesion is not described as malignant or of another tissue type.
Do not use for
Do not use this code for lipomas in a different body site, such as the trunk or shoulder. Do not use it if the documentation indicates a malignant tumor or the site is unspecified; check documentation.
Coding tip
Confirm both the benign nature and the exact left-arm location in the provider note before assigning D17.22.
