What This Code Means
H26.8 is the ICD-10-CM diagnosis code for other specified cataract. A clouding of the lens that does not fit into other cataract categories, such as cataracts from unusual causes or combinations of factors. H26.8 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).
H26.8 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 specified but unusual cataracts; document the specific characteristics in the medical record.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H26.8 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 specified but unusual cataracts; document the specific characteristics in the medical record
- •Attempt to use more specific codes first; use H26.8 only when other codes do not apply
