Poisoning by other antidepressants, assault, sequela

This code signifies a long-term health condition or complication resulting from an intentional overdose or exposure to an antidepressant other than a tricyclic antidepressant, selective serotonin reuptake inhibitor (SSRI), or monoamine oxidase inhibitor (MAOI), where the poisoning was inflicted by another person. It indicates that the acute phase of the poisoning has passed, and the patient is now experiencing residual effects.

Apply this code when documenting a sequela (e.g., chronic organ damage, neurological deficits, persistent psychological issues) directly attributable to a past assault by poisoning with an "other antidepressant." This is used for follow-up encounters when the initial injury has healed, but the patient continues to suffer from the lasting consequences.

• Always use this code as a secondary diagnosis, following a code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past antidepressant poisoning that was an assault.
• Verify the antidepressant involved is not a tricyclic, SSRI, or MAOI, as those have more specific codes.
