What This Code Means
Y07.434 is the ICD-10-CM diagnosis code for female friend of parent (co-residing in household), perpetrator of maltreatment and neglect. A female friend of a parent who lives in the same household is identified as the person who caused maltreatment or neglect to another individual. Y07.434 sits in the ICD-10-CM chapter for external causes of morbidity (v00-y99), within the section covering assault (x92-y09).
Y07.434 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.
Use this code when the perpetrator is specifically a female friend of the patient's parent and they reside together in the same household.
