Is Y93.H3 an HCC code?
No. Y93.H3 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
Y93.H3 is the ICD-10-CM diagnosis code for activity, building and construction. Injury or health event that occurred while the person was building or doing construction work. Y93.H3 sits in the ICD-10-CM chapter for external causes of morbidity (v00-y99), within the section covering supplementary factors related to causes of morbidity classified elsewhere (y90-y99).
Y93.H3 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.
Common with falls, struck-by injuries, or crush injuries on construction sites.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Y93.H3 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
