Poisoning by unsp antipsychot/neurolept, self-harm, sequela

This code signifies a long-term consequence or late effect resulting from an intentional self-poisoning event involving an unspecified antipsychotic or neuroleptic medication. The initial acute poisoning has resolved, but the patient continues to experience residual health problems directly attributable to that past event. This could include chronic organ damage, neurological deficits, or other persistent medical issues.

Use this code when documenting a patient presenting with a current medical condition that is a direct sequela of a past intentional self-harm poisoning by an unspecified antipsychotic or neuroleptic. This applies when the acute phase of the poisoning is no longer active, and the patient is being treated for the chronic effects. For example, a patient with persistent liver damage years after an overdose attempt.

• Always sequence this sequela code after the code for the specific residual condition being treated.
• Ensure documentation clearly links the current condition to the past intentional self-harm poisoning by an unspecified antipsychotic/neuroleptic.
• Do not use this code for the acute poisoning event itself; it is exclusively for the late effects.
