What This Code Means
Y93.85 is the ICD-10-CM diagnosis code for activity, choking game. Injury or health event resulting from participation in a choking game or similar asphyxiation activity. Y93.85 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).
Y93.85 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 serious code often associated with pediatric and adolescent cases; document any loss of consciousness or resuscitation efforts.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Y93.85 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
