Adverse effect of MAO inhib antidepressants, sequela

This code signifies a long-term or residual condition resulting from an adverse reaction to monoamine oxidase inhibitor (MAOI) antidepressants. It indicates that the initial adverse effect has resolved, but a lasting health problem or complication persists.

Apply this code when documenting a patient's current health status that is a direct consequence of a past adverse event related to MAOI antidepressant use. This includes chronic neurological deficits, persistent organ damage, or other lasting sequelae that developed after the acute adverse effect subsided.

• Always use this code as a secondary diagnosis, following the code for the specific sequela.
• Ensure documentation clearly links the current condition to a previous adverse effect of an MAOI.
• Do not use for acute adverse effects; this code is specifically for residual conditions.
