What This Code Means
D17.1 is the ICD-10-CM diagnosis code for benign lipomatous neoplasm of skin and subcutaneous tissue of trunk. A noncancerous fatty tumor in the skin or tissue under the skin of the chest, abdomen, or back. D17.1 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).
D17.1 is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
This code covers the trunk region including chest wall, abdominal wall, and back.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for D17.1 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
