Poisoning by unsp antipsychot/neurolept, acc, sequela

This code indicates a patient is experiencing a long-term effect or complication from an accidental overdose or exposure to an unspecified antipsychotic or neuroleptic medication. The initial acute event has resolved, but ongoing issues related to the poisoning persist.

Apply this code when documenting a sequela, such as chronic neurological deficits, organ damage, or persistent psychiatric symptoms, that are directly attributable to an accidental poisoning by an antipsychotic or neuroleptic drug. This code is appropriate for follow-up care after the acute poisoning has been treated.

• Always sequence a sequela code after the code for the specific condition or symptom being treated.
• Ensure documentation clearly links the current condition to the past accidental poisoning.
• Do not use this code for acute poisoning events; use the appropriate acute poisoning code (without the "S" seventh character) instead.
