Adverse effect of phenothiaz antipsychot/neurolept, sequela

This code signifies a long-term or residual condition resulting from an adverse reaction to phenothiazine antipsychotics or other neuroleptic medications. These sequelae are persistent health problems that arose after the initial adverse effect of the drug had resolved. Examples include tardive dyskinesia or other chronic movement disorders.

Use this code when documenting a patient's current condition that is a direct, lasting consequence of a past adverse effect from phenothiazine antipsychotics or neuroleptics. This applies when the acute adverse drug reaction has passed, but a chronic, related health issue persists. It is appropriate for conditions like persistent extrapyramidal symptoms or tardive syndromes.

• Always sequence this code after the code for the specific sequela (e.g., G24.01 for drug-induced tardive dyskinesia).
• Ensure documentation clearly links the current condition to a past adverse effect of a phenothiazine or neuroleptic.
• Do not use for acute adverse effects; this code is specifically for sequelae.
