    (V01–Y99)
    • Assault
      (X92-Y09)
      • Perpetrator of assault, maltreatment and neglect

Y07.9 is a billable diagnosis code used to specify a medical diagnosis of unspecified perpetrator of maltreatment and neglect. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

Unspecified diagnosis codes like Y07.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Patient Education


Child Abuse

Child abuse is doing something or failing to do something that results in harm to a child or puts a child at risk of harm. Child abuse can be physical, sexual or emotional. Neglect, or not providing for a child's needs, is also a form of abuse.

Most abused children suffer greater emotional than physical damage. An abused child may become depressed. He or she may withdraw, think of suicide or become violent. An older child may use drugs or alcohol, try to run away or abuse others.

Child abuse is a serious problem. If you suspect a child is being abused or neglected, call the police or your local child welfare agency.

Elder Abuse

Many older people are victims of elder abuse. It is the mistreatment of an older person, usually by a caregiver. It can happen within the family. It can also happen in assisted living facilities or nursing homes.

The mistreatment may be:

  • Physical, sexual, or emotional abuse
  • Neglect or abandonment
  • Financial abuse - stealing of money or belongings

Possible signs of elder abuse include unexplained bruises, burns, and injuries. There may also be bed sores and poor hygiene. The person may become withdrawn, agitated, and depressed. There may be a sudden change in the person's financial situation.

Elder abuse will not stop on its own. Someone else needs to step in and help. If you think that an older person is in urgent danger, call 911. Otherwise, contact adult protective services.
