ICD-10 Code D17.71 – Benign lipomatous neoplasm of kidney (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D17.71 – Benign lipomatous neoplasm of kidney
What it is
This code identifies a benign fatty tumor arising in the kidney. It indicates a noncancerous lipomatous neoplasm documented as being located in renal tissue.
Clinical signs
Clinical features vary; refer to documentation. Imaging or pathology may describe a well-defined renal mass with fat-containing characteristics, but you should code only when the record clearly states a benign lipomatous neoplasm of the kidney.
When to use this code
Use D17.71 when the provider documents a benign lipomatous tumor of the kidney, such as a renal lipoma or similar benign fatty lesion. Assign it from imaging, surgical, or pathology documentation that specifically identifies the kidney as the site. Do not infer the diagnosis from a nonspecific renal mass.
Do not use for
Do not use this code for malignant kidney tumors, unspecified renal masses, or lipomatous lesions in other organs. Check documentation if the record does not clearly confirm benign behavior and renal origin.
Coding tip
Code only when both benign nature and kidney location are explicitly documented.
