What This Code Means
C44.1922 is the ICD-10-CM diagnosis code for other specified malignant neoplasm of skin of right lower eyelid, including canthus. This code describes a type of skin cancer (other than melanoma) that has developed on the right lower eyelid or the corner of the eye. It represents a malignant tumor of the skin in this specific location. C44.1922 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering melanoma and other malignant neoplasms of skin (c43-c44).
C44.1922 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.
Verify laterality is documented as 'right' in the medical record before assigning this code; if left side or bilateral, different codes apply.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for C44.1922 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify laterality is documented as 'right' in the medical record before assigning this code; if left side or bilateral, different codes apply
- •Confirm the histological type is documented as 'other specified' malignant neoplasm (not melanoma, basal cell, or squamous cell) to ensure accurate code selection
