Is W13.9XXD an HCC code?

No. W13.9XXD 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

W13.9XXD is the ICD-10-CM diagnosis code for fall from, out of or through building, not otherwise specified, subsequent encounter. W13.9XXD sits in the ICD-10-CM chapter for external causes of morbidity (v00-y99), within the section covering slipping, tripping, stumbling and falls (w00-w19).

W13.9XXD 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.

W13.9XXD is a billable ICD-10-CM code that can be reported on claims but does not currently contribute to a Medicare Advantage member's RAF score under any CMS risk adjustment model (V28, V24, ESRD, or RxHCC). Coders reviewing W13.9XXD should check whether additional documentation would support a more specific child code in the same hierarchy that does map to a payment HCC, capturing the correct specificity is the highest-impact RAF improvement available within accurate coding.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for W13.9XXD sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
