Vagus Nerve Stimulation

Vagus nerve stimulation may be considered medically necessary as a treatment of medically refractory seizures.

Vagus nerve stimulation is considered investigational as a treatment of other conditions, including but not limited to depression, heart failure, upper-limb impairment due to stroke, essential tremor, headaches, fibromyalgia, tinnitus, and traumatic brain injury.

Transcutaneous (nonimplantable) vagus nerve stimulation devices are considered investigational for all indications.
