Is D30.12 an HCC code?

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
D30.12 is the ICD-10-CM diagnosis code for benign neoplasm of left renal pelvis. A non-cancerous tumor located in the left kidney's collection area where urine gathers before entering the ureter. D30.12 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).
D30.12 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.
Ensure documentation specifies left side to differentiate from D30.11.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D30.12 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
