Unsp place in prison as place

This code indicates that an injury or adverse event occurred within a correctional facility, but the specific location within the prison (e.g., cell, yard, infirmary) is not documented. It signifies that the patient was incarcerated at the time of the external cause.

Apply this code when medical documentation clearly states an injury or condition resulted from an external cause that took place within a prison setting, but no further detail about the exact location is provided. This is appropriate for incidents like assaults, falls, or self-harm occurring within the general confines of a correctional institution.

• Always sequence this as a secondary code, following the primary code for the injury or condition.
• Only use this code when the documentation explicitly states "prison" or "correctional facility" and lacks specificity regarding the internal location.
• Avoid using this code if a more specific "place of occurrence" code within a prison setting (e.g., Y92.141 for cell block) is available and supported by documentation.
