What This Code Means
C44.602 is the ICD-10-CM diagnosis code for unspecified malignant neoplasm of skin of right upper limb, including shoulder. A malignant skin cancer of the right upper arm or shoulder area where the specific type (basal cell, squamous cell, or other) has not been determined or is unspecified. C44.602 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering melanoma and other malignant neoplasms of skin (c43-c44).
C44.602 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.
The '2' indicates right side; use C44.609 for left side and C44.601 for unspecified side.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for C44.602 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
