Poisoning by other antidepressants, assault, subs encntr

This code indicates a patient presenting with adverse effects or toxicity resulting from an intentional overdose of an antidepressant medication other than a tricyclic antidepressant (TCA) or selective serotonin reuptake inhibitor (SSRI). The poisoning was inflicted by another person with intent to harm, and the patient is receiving follow-up care for the sequelae of this event.

Use this code for patients admitted for ongoing management of complications from an assault involving poisoning by an "other antidepressant," such as a serotonin-norepinephrine reuptake inhibitor (SNRI) or atypical antidepressant. This applies to encounters after the initial treatment of the acute poisoning, such as for organ damage, neurological deficits, or psychiatric sequelae.

• Requires a seventh character "D" for subsequent encounter, indicating ongoing care after the initial treatment.
• Always sequence this code after the primary diagnosis describing the specific manifestation of the poisoning (e.g., cardiac arrhythmia, liver failure).
• Ensure documentation clearly specifies the antidepressant class (not TCA or SSRI) and confirms the assaultive intent.
