NPI records don't show insurance, openings or telehealth. Call the office to confirm those before you book.
Psychologists hold a doctorate (PhD, PsyD or EdD) and a state license. They provide therapy and are the only clinicians on this list trained to run formal psychological and diagnostic testing. Most cannot prescribe.
Before you call
Ask whether they're taking new patients, which insurance plans they're in, what a session costs without insurance, and whether they see people by video. You can check any clinician's license with your state licensing board, and their NPI record at the CMS NPI Registry.
The NPI Registry lists 37 psychologists with a practice address in Smithtown. Some work only inside a hospital, clinic or school, and a few may have retired without closing their NPI, so the number seeing new patients is lower.
Do these psychologists take insurance?
NPI records don't include insurance. Call the office or check your insurer's directory. How coverage works.
