Poisoning by fentanyl or fentanyl analogs, self-harm, subs

This code signifies a patient presenting for follow-up care related to an intentional overdose of fentanyl or fentanyl analogs. The initial self-harm event has already occurred, and the patient is now receiving ongoing treatment, monitoring, or management for the sequelae of that poisoning.

Apply this code when documenting subsequent encounters for patients who previously attempted suicide or self-harm using fentanyl. This includes visits for ongoing medical management of organ damage, psychiatric evaluation, substance abuse counseling, or medication adjustments following the initial acute poisoning.

• Ensure documentation clearly states "intentional self-harm" and "subsequent encounter."
• Always sequence this code after any codes for the specific manifestations or complications of the poisoning.
• Do not use for initial acute care; a different 7th character (A) would be appropriate for the initial encounter.
