What this specialty covers
A neurological surgeon provides the operative and non-operative management (i.e., prevention, diagnosis, evaluation, treatment, critical care, and rehabilitation) of disorders of the central, peripheral, and autonomic nervous systems, including their supporting structures and vascular supply; the evaluation and treatment of pathological processes which modify function or activity of the nervous system; and the operative and non-operative management of pain. A neurological surgeon treats patients with disorders of the nervous system; disorders of the brain, meninges, skull, and their blood supply, including the extracranial carotid and vertebral arteries; disorders of the pituitary gland; disorders of the spinal cord, meninges, and vertebral column, including those which may require treatment by spinal fusion or instrumentation; and disorders of the cranial and spinal nerves throughout th
Reading the sole-proprietor share
For neurological surgery, the sole-proprietor share describes NPPES records in which the registrant has self-reported that designation, not all surgeons who work outside a hospital or health system. The 13.9% share, based on 1,542 flagged records, is therefore an imperfect proxy for private practice because it may not capture group ownership, employment arrangements, organization NPIs, or updates to the field.

Data notes
- The sole-proprietor field is self-reported by the provider in NPPES and is an imperfect proxy for private practice.
- A sole-proprietor count shown as <11 is suppressed: the true value is below 11, which could include zero.
- - These figures describe active NPI records with a primary taxonomy, not patient volume, clinical activity, or practice size.
- - An NPI's first-enumeration year does not establish when a provider began practicing neurological surgery, and state counts reflect NPI reporting rather than service availability.
- Providers are counted once, by their primary taxonomy code only.
Common questions
How many neurological surgery physicians are there in the United States?
There are 11,089 active NPI records nationally with Neurological Surgery Physician as the primary taxonomy. This is a count of NPI records, not necessarily a direct census of unique practicing physicians.
How many neurological surgeons are in private practice?
NPPES flags 1,542 records, or 13.9%, as sole proprietors. That figure is not a definitive count of neurological surgeons in private practice because the field is self-reported and does not capture every ownership or employment arrangement.
Which states have the most neurological surgery physicians?
The largest reported state counts are in California, Florida, Texas, New York, and Pennsylvania.
How many neurological surgery NPIs were first enumerated recently?
The most recent full years available show 180 NPIs first enumerated in 2023, 200 in 2024, and 204 in 2025.
