D17.21 ICD-10-CM Code: Benign lipomatous neoplasm of skin and subcutaneous tissue of right arm

D17.21 is the ICD-10-CM diagnosis code for benign lipomatous neoplasm of skin and subcutaneous tissue of right arm. A benign fatty tumor (lipoma) located in the skin or fatty tissue of the right arm. D17.21 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).

D17.21 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

This code is specific to the right arm; use D17.22 for left arm lipomas.
