What This Code Means
C44.519 is the ICD-10-CM diagnosis code for basal cell carcinoma of skin of other part of trunk. A basal cell carcinoma that develops on other areas of the trunk (torso) such as the back, abdomen, or sides. C44.519 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering melanoma and other malignant neoplasms of skin (c43-c44).
C44.519 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.
Document the specific trunk location when possible for clinical clarity.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for C44.519 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
