What This Code Means

H26.09 is the ICD-10-CM diagnosis code for other infantile and juvenile cataract. A clouding of the lens in a child's eye that doesn't fit into other specific cataract categories. H26.09 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).

H26.09 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 is a catch-all code for infantile and juvenile cataracts not classified elsewhere; review documentation for more specific cataract types first.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H26.09 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • This is a catch-all code for infantile and juvenile cataracts not classified elsewhere; review documentation for more specific cataract types first
  • Ensure the cataract is documented as occurring in infancy or childhood to justify this code
