About Y07.490

Y07.490 is the ICD-10-CM diagnosis code for male cousin, 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Y07.49 (other family member, perpetrator of maltreatment and neglect), Y07.490 is specifically for male cousin, perpetrator of maltreatment and neglect. Related codes cover female cousin, perpetrator of maltreatment and neglect (Y07.491) and other family member, perpetrator of maltreatment and neglect (Y07.499).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as E967.7 (perpetrator of child and adult abuse, by other relative) and E968.4 (assault by criminal neglect).
