W16.212A ICD-10-CM Code: Fall in (into) filled bathtub causing other injury, initial encounter

W16.212A is the ICD-10-CM diagnosis code for fall in (into) filled bathtub causing other injury, initial encounter. W16.212A 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).

W16.212A 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.

W16.212A 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 W16.212A 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.
