798.9
ICD-9-CMThis code signifies a death that occurred without a witness present at the time of the event. It indicates that the individual was found deceased, and the moment of death was not observed by another person. This diagnosis is typically used in cases where the circumstances surrounding the death are initially unclear or require further investigation.
This code is appropriate for cases documented as "unattended death" by law enforcement, medical examiners, or coroners. It is used when the patient is found deceased and there is no immediate medical explanation or witness to the death. Documentation should clearly state that the death was unwitnessed.
