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. Ask what kind of sleep study is offered, where it takes place, and whether you sleep there overnight. Find out whether the practice runs a structured sleep program and how many sessions it involves. Confirm the cancellation policy, since missed-appointment fees differ between clinics. 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. Because listing data can lag behind the practice, check the essentials by phone before booking.
