Poisn by slctv seroton/norepineph reup inhibtr,slf-hrm, subs

This code indicates a patient experienced an adverse effect from a selective serotonin and norepinephrine reuptake inhibitor (SNRI) due to a deliberate act of self-harm. The encounter being coded is not the initial presentation for this poisoning, but a follow-up visit related to its management or complications. This implies ongoing care after the acute phase of the self-poisoning event.

Use this code for subsequent encounters when a patient is receiving ongoing treatment, monitoring, or follow-up care for an SNRI poisoning that was intentionally self-inflicted. This includes visits for managing residual symptoms, complications, or psychiatric evaluation after the initial acute treatment. It is appropriate for any encounter after the initial hospitalization or emergency department visit related to the self-harm.

• Always sequence this code after the primary diagnosis for the specific manifestation of the poisoning, if applicable.
• Ensure documentation clearly specifies the intent as "intentional self-harm" and that the encounter is not the initial presentation.
• Verify the medication involved is specifically an SNRI to differentiate from other antidepressant classes.
