What This Code Means
H27.02 is the ICD-10-CM diagnosis code for aphakia, left eye. Aphakia of the left eye is a condition where the lens of the left eye is absent, either due to surgical removal (such as cataract surgery) or congenital absence. This results in loss of the eye's natural focusing ability and typically requires corrective lenses or other interventions to restore vision. H27.02 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).
H27.02 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.
Verify whether aphakia is post-surgical (most common) or congenital, as this may affect documentation and related procedure coding.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H27.02 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
