Underdosing of unsp antipsychotics and neuroleptics, subs

This code signifies a patient's underdosing of an antipsychotic or neuroleptic medication, where the specific drug is not documented. This underdosing is causing an adverse effect or complication, and the patient is presenting for follow-up care after the initial treatment of the underdosing event.

Use this code when a patient is seen for ongoing management or monitoring related to the underdosing of an unspecified antipsychotic or neuroleptic. This applies to situations where the initial adverse effect has been addressed, but the patient requires further care. Examples include follow-up appointments to adjust medication, manage residual symptoms, or monitor for recurrence of the underlying psychiatric condition due to the underdosing.

• Always sequence this code after the code(s) for the specific adverse effect or complication resulting from the underdosing.
• Ensure documentation clearly states "underdosing" and specifies that the encounter is for subsequent care.
• If the specific antipsychotic or neuroleptic is known, use a more specific code from the T43.5 category.
