Poisoning by unsp antidepressants, self-harm, sequela

This code signifies a long-term consequence or complication arising from a deliberate overdose of an unspecified antidepressant medication. The initial poisoning event, which was an act of intentional self-harm, has led to persistent health issues requiring ongoing medical attention.

Apply this code when documenting a patient presenting with a current sequela (e.g., organ damage, neurological deficit, chronic pain) directly attributable to a past intentional self-poisoning with an antidepressant, where the specific antidepressant agent is not identified. This code is appropriate for follow-up encounters addressing these lasting effects, not for the initial acute poisoning.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past intentional antidepressant overdose.
• Do not use this code for acute poisoning; use the appropriate acute poisoning code with the 7th character "A" for initial encounter.
