What This Code Means
H27.129 is the ICD-10-CM diagnosis code for anterior dislocation of lens, unspecified eye. Complete forward displacement of the lens into the front chamber of an unspecified eye. H27.129 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of lens (h25-h28).
H27.129 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.
Query provider for specific eye involvement (right, left, or bilateral) to assign the most accurate code.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H27.129 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
