Adverse effect of unsp antipsychotics and neuroleptics, subs

This code signifies a patient experiencing an unintended and harmful reaction to an antipsychotic or neuroleptic medication, where the specific drug causing the adverse effect is not documented. This particular code is used when the patient is receiving follow-up care for this adverse event after the initial treatment.

Apply this code when a patient presents for ongoing management of an adverse effect from an antipsychotic or neuroleptic, and the specific medication responsible is unknown or not specified in the medical record. This would be used for subsequent visits related to the adverse effect, such as monitoring symptoms, adjusting treatment, or further investigation.

• Ensure documentation clearly indicates the encounter is subsequent to the initial treatment for the adverse effect.
• Only use this code when the specific antipsychotic or neuroleptic is truly unspecified; otherwise, a more specific code should be chosen.
• Always sequence this code after the primary diagnosis for which the patient is being treated, if applicable.
