Poisoning by unsp antipsychot/neurolept, undetermined, subs

This code signifies a poisoning event involving an unspecified antipsychotic or neuroleptic medication where the intent (e.g., accidental, intentional self-harm) cannot be determined. The "D" seventh character indicates that this encounter is for follow-up care after the initial treatment of the poisoning.

Apply this code when a patient presents for ongoing management, monitoring, or treatment of complications arising from an antipsychotic/neuroleptic poisoning, and the specific drug involved is unknown. This is appropriate for subsequent visits after the acute phase has passed, but the intent of the poisoning remains unclear.

• Ensure the documentation clearly states that the specific antipsychotic or neuroleptic agent is not identified.
• Verify that the encounter is for follow-up care related to the poisoning, not the initial treatment.
• Confirm that the intent of the poisoning is explicitly documented as "undetermined" or cannot be ascertained from the medical record.
