C44.60 ICD-10-CM Code: Unspecified malignant neoplasm of skin of upper limb, including shoulder

C44.60 is the ICD-10-CM diagnosis code for unspecified malignant neoplasm of skin of upper limb, including shoulder. C44.60 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering melanoma and other malignant neoplasms of skin (c43-c44).

Header codes like C44.60 cannot be reported on claims directly, they organize child codes that share clinical context but the actual diagnosis must be coded to the highest level of specificity supported by the documentation. Coders should look at C44.60's child codes and select the one that matches the patient's documented presentation, since payers reject header codes submitted as the primary diagnosis. For risk adjustment workflows, header codes never contribute to a Medicare Advantage member's RAF score on their own; only billable child codes that happen to map to a payment HCC affect risk-adjusted plan payments.
