Adverse effect of unsp antipsychot/neurolept, sequela

This code signifies a long-term or residual condition resulting from an adverse reaction to an unspecified antipsychotic or neuroleptic medication. It indicates that the initial adverse effect has resolved, but a lasting consequence or complication persists. This could include chronic movement disorders, persistent metabolic changes, or other enduring health issues.

Apply this code when documenting a patient's current health status that is a direct, lasting consequence of a past adverse reaction to an antipsychotic or neuroleptic drug, and the specific drug involved is not documented. This is appropriate for conditions like tardive dyskinesia or persistent metabolic syndrome that developed after an adverse drug event and are now considered chronic. It should be used after the acute phase of the adverse effect has passed.

• Always sequence this code after the code for the specific sequela (e.g., G24.0 for tardive dyskinesia).
• Ensure documentation clearly links the current condition to a past adverse effect of an antipsychotic/neuroleptic.
• Only use this code when the specific antipsychotic or neuroleptic agent is not identified in the medical record.
