S92.512K ICD-10-CM Code: Displaced fracture of proximal phalanx of left lesser toe(s), subsequent encounter for fracture with nonunion

S92.512K is the ICD-10-CM diagnosis code for displaced fracture of proximal phalanx of left lesser toe(s), subsequent encounter for fracture with nonunion. S92.512K sits in the ICD-10-CM chapter for injury, poisoning and certain other consequences of external causes (s00-t88), within the section covering injuries to the ankle and foot (s90-s99).

S92.512K 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.

S92.512K 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 S92.512K 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.
