Is H02.519 an HCC code?

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
H02.519 is the ICD-10-CM diagnosis code for abnormal innervation syndrome unspecified eye, unspecified eyelid. A condition where the nerves controlling eyelid movement are not functioning properly, but neither the eye (right or left) nor the specific eyelid location is specified. H02.519 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of eyelid, lacrimal system and orbit (h00-h05).
H02.519 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 the least specific code in this series; use only when laterality and eyelid location cannot be determined.
