What This Code Means
H17.819 is the ICD-10-CM diagnosis code for minor opacity of cornea, unspecified eye. Small cloudy areas on the clear front part of the eye when it is unclear which eye or both eyes are affected. H17.819 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of sclera, cornea, iris and ciliary body (h15-h22).
H17.819 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.
