It is worth confirming the referral rules first, since some practices require a GP letter and others do not. Confirm how payment works — up front, on the day, or billed afterwards — and whether insurance plans can be billed directly. Confirm whether the practice runs its own sleep laboratory or refers patients elsewhere for testing. If the practice sits inside a larger medical center, ask which building and floor to go to. Ask whether appointment confirmations and any forms can be sent before the visit. Ask what to bring: a medication list, any referral letter, a sleep diary, and results from earlier studies. If you need an interpreter, ask whether one can be arranged for the appointment. Details on this page come from public records and can change, so confirm them with the practice before you travel.
