Ask about referral requirements up front; they vary by practice and by how the consultation is paid for. Ask for the total expected cost before booking, separating the consultation from any study or device fee. 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 what to bring: a medication list, any referral letter, a sleep diary, and results from earlier studies. If telehealth is offered, ask which parts of the assessment can be done remotely and which need a visit. Because listing data can lag behind the practice, check the essentials by phone before booking.
