What This Code Means
C44.622 is the ICD-10-CM diagnosis code for squamous cell carcinoma of skin of right upper limb, including shoulder. A squamous cell carcinoma (a type of skin cancer) that develops on the right upper arm or shoulder area. C44.622 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering melanoma and other malignant neoplasms of skin (c43-c44).
C44.622 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 C44.621 for unspecified side and C44.629 for left side.
