Is D16.30 an HCC code?

What This Code Means
D16.30 is the ICD-10-CM diagnosis code for benign neoplasm of short bones of unspecified lower limb. A noncancerous tumor of the small bones in the lower leg or foot, but the specific leg is not identified. D16.30 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).
D16.30 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.
Use this code only when laterality (left vs right) cannot be determined; if known, use D16.31 or D16.32 instead.
