Poisoning by fentanyl or fentanyl analogs, assault, subs

This code signifies a patient presenting for follow-up care or treatment of complications arising from fentanyl or fentanyl analog poisoning that occurred as a result of an assault. The initial poisoning event was intentionally inflicted by another person, and the current encounter addresses ongoing medical needs related to that incident.

Use this code for subsequent visits where a patient is being managed for sequelae of fentanyl poisoning due to an assault, such as ongoing organ damage, withdrawal symptoms, or psychiatric complications. This applies to encounters after the initial acute treatment, for example, during rehabilitation or long-term monitoring.

• Ensure documentation clearly states the poisoning was due to an assault and this is not the initial encounter.
• Always sequence this code after any codes for the specific manifestations or complications of the poisoning.
• Consider additional codes for any associated injuries or psychiatric conditions resulting from the assault.
