What This Code Means
D04.71 is the ICD-10-CM diagnosis code for carcinoma in situ of skin of right lower limb, including hip. Abnormal skin cells on the right leg or hip that have the potential to become cancer but have not yet invaded deeper layers of skin. D04.71 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering in situ neoplasms (d00-d09).
D04.71 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, 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 includes the entire right lower limb from hip to toes; ensure laterality is clearly documented.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for D04.71 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
