About Y07.021

Y07.021 is the ICD-10-CM diagnosis code for Wife, former, 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 Y07.02 (Wife, perpetrator of maltreatment and neglect), Y07.021 is specifically for Wife, former, perpetrator of maltreatment and neglect. Related codes cover current, perpetrator of maltreatment and neglect (Y07.020).

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 was added in FY2023, effective October 1, 2022.
