What This Code Means
Z46.0 is the ICD-10-CM diagnosis code for encounter for fitting and adjustment of spectacles and contact lenses. A patient visit to get fitted for or have adjustments made to eyeglasses or contact lenses. Z46.0 sits in the ICD-10-CM chapter for factors influencing health status and contact with health services (z00-z99), within the section covering encounters for other specific health care (z40-z53).
Z46.0 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 code is used for routine eye care visits focused on vision correction devices, not for eye exams or treatment of eye diseases.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Z46.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
