Adverse effect of oth antipsychotics and neuroleptics, init

This code signifies an undesirable or harmful reaction experienced by a patient due to the therapeutic use of an antipsychotic or neuroleptic medication not specifically classified elsewhere. These reactions are unintended and occur at standard dosages, rather than from poisoning or underdosing.

Use this code when documenting a patient's initial presentation for an adverse effect from an antipsychotic or neuroleptic drug, such as akathisia, tardive dyskinesia, or neuroleptic malignant syndrome, when the specific drug is not detailed in other T43.5 subcategories. This applies when the medication was prescribed and taken as directed.

• Always sequence the manifestation code first, followed by this adverse effect code.
• Ensure the documentation clearly states the reaction is an adverse effect, not poisoning or underdosing.
• Verify the specific antipsychotic/neuroleptic agent is not covered by a more specific T43.5 subcategory.
