Y07: Other maltreatment

Y07.9: By unspecified person

The term "By unspecified person" from WHO ICD-10 code Y07.9 is typically used in the context of medical or health records to catalogue instances where an individual has suffered harm or injury inflicted by another person, the identity of whom is unknown or undisclosed. This category is generally used in cases involving physical assault or abuse, unintentional or intentional harm, but where the perpetrator isn't clearly identified. It covers a vast range of potential physical injuries and psychological traumas. The nature and severity of symptoms largely depend on the type of harm done, its intensity, and frequency. This might include, but is not limited to, physical pain, symptoms of injuries like bruises or fractures, and mental health issues such as anxiety, depression, and post-traumatic stress disorder.
