What This Code Means
H16.339 is the ICD-10-CM diagnosis code for sclerosing keratitis, unspecified eye. A chronic condition where the cornea becomes scarred and hardened when the specific eye affected is not documented. H16.339 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).
H16.339 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.
Use this code only when laterality is not specified; query provider for clarification on which eye is affected.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H16.339 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
