How to choose a sleep doctor in Smithtown

Start with your symptoms, referral status, and insurance network. Compare the listed provider type, address, phone number, and any accreditation shown. If a listing does not show a clinician name or credentials, call the office to ask who will evaluate you and whether they accept your coverage.

What to expect

A sleep evaluation often begins with a medical history, symptom review, and a discussion of sleep habits. A clinician may recommend a sleep study, which can be performed in a lab or at home depending on the clinical question. For more background, see sleep study information and home sleep study information. Follow the instructions provided by the ordering clinician and the testing site.
