Poisn by slctv serotonin reuptake inhibtr, self-harm, init

This code signifies a patient presenting with adverse effects or toxicity resulting from the deliberate self-administration of a selective serotonin reuptake inhibitor (SSRI) with the intent to cause harm. The patient is in the initial phase of treatment for this poisoning event.

Apply this code when documenting an emergency department visit or initial inpatient admission for an SSRI overdose that is explicitly identified as an attempted suicide or other intentional self-harm. This code is appropriate for the first encounter where the poisoning is diagnosed and treatment is initiated.

• Always sequence this code first for the poisoning event, followed by codes for any associated manifestations or complications.
• Requires an additional code for the specific SSRI involved, if known (e.g., from the T43.21- or T43.22- subcategories).
• Do not use for accidental poisonings or adverse effects from therapeutic use; those scenarios require different intent codes.
