Clinical & Coding Specifications

Clinical Context

A 42-year-old patient with treatment-resistant major depressive disorder is referred for MRI-guided repetitive magnetic stimulation targeting the precuneus as part of a personalized neuromodulation plan. The multidisciplinary workflow begins with psychiatric evaluation and neuroimaging (MRI) to identify the precuneus target and create a neuronavigation plan. On treatment days the patient arrives to an outpatient neuromodulation clinic or hospital outpatient department, is screened for MRI-compatible implants and seizure risk, and has the neuronavigation system registered to their MRI. The provider delivers a daily session of magnetic stimulation using MRI–guided neuronavigation to precisely localize the precuneus target, monitors patient response, adjusts stimulation parameters per the individualized plan, and documents treatment delivery and any immediate adverse effects. Typical sites of service include outpatient neuromodulation centers, hospital outpatient departments, and specialized psychiatry clinics equipped with MRI-guided neuronavigation.
