Unspecified perpetrator of maltreatment and neglect

This code signifies a situation where an individual has experienced harm due to maltreatment or neglect, but the specific person responsible for the abuse or neglect cannot be identified or documented. It indicates that the nature of the maltreatment is known, but the perpetrator remains unknown.

Use this code when documentation clearly indicates maltreatment or neglect has occurred, but the identity of the abuser or neglecter is not specified. This is appropriate in cases where the patient is unable or unwilling to identify the perpetrator, or when the investigation is ongoing and no specific individual has been implicated.

• Always sequence this code after the primary injury or condition resulting from the maltreatment.
• Ensure documentation supports that an act of maltreatment or neglect occurred, even if the perpetrator is unknown.
• Avoid using this code if a specific perpetrator is identified, even if their relationship to the victim is not fully detailed.
