Poisoning by benzodiazepines, assault, subsequent encounter

This code signifies a patient presenting for follow-up care related to an intentional overdose or poisoning by a benzodiazepine, where the substance was administered by another person with the intent to harm. It indicates that the initial treatment for the acute poisoning has already occurred, and the current encounter is for ongoing management, complications, or recovery.

Apply this code when documenting subsequent visits for a patient who was previously treated for benzodiazepine poisoning due to an assault. This includes appointments for monitoring organ function, managing withdrawal symptoms, addressing psychological sequelae, or follow-up for any lingering physical effects from the poisoning event.

• Always pair this code with an external cause code (e.g., Y07.9XXD) to fully describe the circumstances of the assault.
• Ensure documentation clearly states the encounter is for follow-up care and not the initial treatment of the acute poisoning.
• Verify that the specific substance involved was a benzodiazepine; differentiate from other psychotropic medications.
