Typical Clinical Scenarios

An adult inpatient with severe, treatment-resistant major depressive disorder admitted after failing multiple medication trials and psychotherapy, who is scheduled for inpatient electroconvulsive therapy as an acute therapeutic intervention to rapidly reduce depressive symptoms and suicidal ideation. The procedure is performed under general anesthesia to induce a controlled therapeutic seizure when the documented therapy does not fit a more specific subtype. Typical codes: GZB4ZZZ
An elderly patient hospitalized for acute psychotic agitation and catatonia unresponsive to pharmacologic management who requires urgent inpatient electroconvulsive therapy to promptly relieve life‑threatening symptoms and restore oral intake and mobility. The ECT is delivered during the admission as an essential treatment and is documented without specification of a more detailed electroconvulsive therapy variant. Typical codes: GZB4ZZZ
A psychiatric inpatient admitted for relapse of bipolar disorder with severe refractory manic episodes after prior courses of electroconvulsive therapy; during the current admission the care team documents administration of ECT as a repeat therapeutic procedure where no more specific procedural subtype is recorded. The procedure is performed to achieve clinical stabilization when previous conservative measures have failed. Typical codes: GZB4ZZZ
