Poisoning by oth antidepressants, self-harm, sequela

This code signifies the long-term or residual effects resulting from a deliberate act of self-poisoning using an antidepressant medication other than a tricyclic antidepressant. It indicates that the patient intentionally ingested an excessive amount of such a substance, and the current encounter addresses a condition or complication directly attributable to that past event. The "sequela" aspect means the acute poisoning event has passed, but its consequences persist.

Use this code when documenting follow-up care for a patient who previously attempted suicide via an overdose of an antidepressant (excluding tricyclics), and the current medical issue is a direct, lasting consequence of that attempt. Examples include chronic organ damage, neurological deficits, or persistent psychological effects directly linked to the past intentional poisoning. This code is appropriate for encounters occurring after the acute phase of the poisoning has resolved.

• Ensure documentation clearly links the current condition to a past intentional self-harm poisoning by an antidepressant.
• Verify the specific antidepressant involved is not a tricyclic; if it is, a different code from the T43.0- category would be appropriate.
• The "S" at the end indicates sequela, meaning this code is for the late effects, not the acute poisoning event itself. Do not use for the initial acute poisoning encounter.
