Underdosing of MAO inhib antidepressants, subs

This code signifies a situation where a patient has not received a sufficient amount of their prescribed monoamine oxidase inhibitor (MAOI) antidepressant medication, and this is being addressed during a follow-up visit. This underdosing could be due to various reasons, such as patient non-adherence, medication supply issues, or an intentional reduction that proved insufficient. The patient is typically being monitored or treated for the consequences of this insufficient dosage.

Use this code when a patient presents for a follow-up visit related to the underdosing of an MAOI antidepressant. This includes scenarios where the patient is experiencing a return or worsening of depressive symptoms due to insufficient medication, or when the clinician is adjusting the dosage after a period of underdosing. It is appropriate for ongoing management and evaluation of the underdosing event.

• Always use in conjunction with other codes to specify the adverse effect or condition being treated due to the underdosing.
• Ensure documentation clearly indicates the underdosing of an MAOI and that the encounter is a subsequent visit for this issue.
• Distinguish from initial encounters (A) or sequela (S) encounters for underdosing.
