What This Code Means

D23.10 is the ICD-10-CM diagnosis code for other benign neoplasm of skin of unspecified eyelid, including canthus. A benign skin growth on the eyelid or the corner of the eye (canthus) when the specific side is not documented or is unspecified. D23.10 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).

D23.10 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.

This is a unspecified code; use only when laterality (left/right) and eyelid location (upper/lower) cannot be determined.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D23.10 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • This is a unspecified code; use only when laterality (left/right) and eyelid location (upper/lower) cannot be determined
  • If documentation specifies the side and location, use the more specific codes D23.11x or D23.12x instead
