Before booking, ask whether a referral or doctor's letter is needed, because requirements differ between practices and how a visit is funded. Request the current fee schedule, including any charge for the sleep study itself and for reporting the results. Confirm whether the practice runs its own sleep laboratory or refers patients elsewhere for testing. 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 telehealth is offered, ask which parts of the assessment can be done remotely and which need a visit. Treat the details here as a directory snapshot and confirm anything time-sensitive with the practice.
