When you call, ask what referral paperwork is required and whether a GP letter must arrive before the visit. Confirm how payment works — up front, on the day, or billed afterwards — and whether insurance plans can be billed directly. Ask which sleep study the practice would use — home testing or an overnight study in a lab — and what each involves. Ask whether appointment confirmations and any forms can be sent before the visit. Confirm the cancellation policy, since missed-appointment fees differ between clinics. Ask who reviews the study results and when you will be told what they show. If you need an interpreter, ask whether one can be arranged for the appointment. Because listing data can lag behind the practice, check the essentials by phone before booking.
