This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Z83.518 is the ICD-10-CM diagnosis code for family history of other specified eye disorder. A family member has an eye disorder other than glaucoma, such as retinal disease, macular degeneration, or other vision conditions. Z83.518 sits in the ICD-10-CM chapter for factors influencing health status and contact with health services (z00-z99), within the section covering persons with potential health hazards related to family and personal history and certain conditions influencing health status (z77-z99).

Z83.518 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 for family history of eye conditions not specifically coded elsewhere, such as retinitis pigmentosa or age-related macular degeneration.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Z83.518 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • Use this code for family history of eye conditions not specifically coded elsewhere, such as retinitis pigmentosa or age-related macular degeneration
  • Do not use this code for glaucoma; use Z83.511 instead
