A neurosurgeon office visit for an established patient is a follow-up visit with a neurosurgeon who specializes in surgical and medical diseases of the brain, spine, and nerves, and conditions that affect the flow of blood to the brain. Common procedures performed by neurosurgeons include anterior cervical discectomy and laminectomy. An established patient office visit is needed if you have seen this doctor before in the last 3 years, otherwise please purchase an office visit for "new patient".
