About Y07.4
Y07.4 is the ICD-10-CM diagnosis code for other family member, perpetrator of maltreatment and neglect. It belongs to category Y07 (perpetrator of assault, maltreatment and neglect), block X92-Y09 (assault) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 8 subcodes must be used instead.
Within Y07, choose Y07.4 (Other family member, perpetrator of maltreatment and neglect) only when documentation doesn't support a more specific option: spouse or partner, perpetrator of maltreatment and neglect (Y07.0), parent (adoptive) (biological), perpetrator of maltreatment and neglect (Y07.1), non-family member, perpetrator of maltreatment and neglect (Y07.5), multiple perpetrators of maltreatment and neglect (Y07.6) and unspecified perpetrator of maltreatment and neglect (Y07.9).
To report this condition, pick the subcode that matches the documentation: Y07.41 (neglect), Y07.42 (neglect), Y07.43 (neglect), Y07.44 (neglect), Y07.45 (neglect), Y07.46 (neglect), Y07.47 (neglect) and Y07.49 (neglect).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
