Sleep resources by region

The science of sleep is the same everywhere; the path to a sleep study is not. These guides explain how referral, public coverage, and treatment funding are generally organised where you live, and point you to official sources so you can confirm the details.

Complete Sleep is an educational publisher. It has no offices, clinics, or affiliated providers in any of these places, and it does not recommend specific clinics. Rules and coverage change — always confirm with the health authority, insurer, or clinician named on the page.

Canada

In Canada, sleep studies are ordered by a physician or nurse practitioner and paid for through provincial health plans when they are medically necessary. In-lab polysomnography is publicly insured in most provinces; coverage of home sleep apnea tests and of CPAP devices varies from province to province, which is why the details live on the province pages below.

United States

In the United States, a sleep study is ordered by a physician — often a primary-care doctor or a sleep specialist — and is usually covered by health insurance when it is medically necessary, frequently after prior authorization. Medicare covers polysomnography and home sleep apnea testing under specific coverage rules, and covers CPAP for an initial trial period that continues only if the device is used consistently.

United Kingdom

In the UK, the route to a sleep study runs through your GP. If obstructive sleep apnoea is suspected, the GP refers you to a hospital sleep or respiratory clinic, which usually arranges an overnight home sleep study first; a full in-lab study is reserved for complex cases.

Australia

In Australia a sleep study is Medicare-rebated when it meets MBS criteria. Since 2018 a GP can refer you directly — without first seeing a sleep or respiratory physician — if validated questionnaires show a high likelihood of moderate-to-severe obstructive sleep apnoea: a STOP-Bang score of 3 or more, an OSA50 of 5 or more, or a high-risk Berlin score, together with an Epworth Sleepiness Scale of 8 or more.
