Toxic effect of halogenated insecticides, self-harm, subs

This code signifies a patient presenting for follow-up care related to a deliberate self-poisoning event involving halogenated insecticides. The initial acute phase of the poisoning has passed, and the patient is now receiving ongoing treatment or monitoring for residual effects. This could include managing organ damage, neurological symptoms, or psychological sequelae.

Apply this code when a patient is seen for subsequent treatment, evaluation, or monitoring after an intentional self-harm attempt using halogenated insecticides. This includes visits for managing chronic complications, rehabilitation, or mental health follow-up directly related to the poisoning. Do not use for the initial acute poisoning encounter.

• Always sequence this code after any codes for the specific manifestations or complications of the poisoning.
• Ensure documentation clearly indicates "intentional self-harm" and "subsequent encounter."
• Do not use this code for accidental exposures or assaults; different codes apply for those scenarios.
