Toxic effect of cyanides, intentional self-harm, subs encntr

This code signifies a patient presenting for follow-up care related to a previous cyanide poisoning event that was intentionally self-inflicted. The patient is no longer in the acute phase of the poisoning but is receiving ongoing treatment, monitoring, or evaluation for sequelae or recovery.

Apply this code for encounters following the initial treatment of an intentional cyanide self-poisoning, such as follow-up appointments for organ damage assessment, psychiatric evaluation, or ongoing supportive care. It is appropriate when the patient is seen after discharge from acute care for the poisoning itself.

• Ensure the encounter is for follow-up care, not the initial acute treatment.
• Verify the intent was self-harm, not accidental or assault.
• Confirm the substance involved was cyanide.
