Sleep studies are used to diagnose sleep disorders such as sleep apnea, periodic limb movement disorder, narcolepsy, restless legs syndrome, insomnia, and REM sleep behavior disorder. There are two types of sleep studies: polysomnography or in-lab (PSG) and home sleep apnea test (HSAT). A sleep study is considered necessary if you answer yes to at least 3 out of 8 questions on a sleep apnea questionnaire. If you are considering getting a sleep study, you will need a referral from a physician and, in some cases, authorization from your health insurance company.

What You'll Learn
Sleep study referrals are required from a physician or primary care provider
Sleep studies are a non-invasive way to diagnose sleep disorders such as sleep apnea, periodic limb movement disorder, narcolepsy, restless leg syndrome, insomnia, and REM sleep behaviour disorder. They can be performed in a lab or at home, and are often recommended by a medical provider or sleep doctor.
Sleep studies are not usually available without a referral from a physician or primary care provider. This is because a sleep study is usually recommended following an extensive review of your medical history, with a special focus on sleep. An exam will also be performed to uncover any common causes of sleep disruption. This is to ensure that the most appropriate study is ordered. In some cases, a patient may be referred directly to a sleep lab without needing to be seen in a sleep clinic first.
If you are experiencing trouble sleeping for more than a month, or are tired during the day for unknown reasons, it is important to see a doctor trained in sleep disorders. They will be able to determine whether a sleep study is necessary and refer you to a sleep lab or sleep clinic if needed.
In some cases, your insurance company may also need to authorise a sleep study. Sleep lab staff can sometimes get approval from your insurance company on your behalf.

Sleep studies can be done in a lab or at home
Sleep studies are diagnostic tests that monitor your sleep to identify any underlying sleep disorders. They can be done in a lab or at home, and each has its own advantages and disadvantages.
In-lab sleep studies, also known as polysomnography (PSG), are comprehensive evaluations that require you to stay overnight at a sleep centre or hospital. A sleep technician monitors your sleep and various functions such as heart rate, breathing, eye movement, brain activity, muscle tone, respiratory effort, airflow, snoring, blood oxygen levels, and body position. It also tracks arm and leg movements. These studies are useful for diagnosing a wide range of sleep disorders, including sleep apnea, periodic limb movement disorder, narcolepsy, restless leg syndrome, and REM sleep behaviour disorder. They are particularly recommended for people with certain heart, breathing, or neuromuscular problems. However, they can be inconvenient as they require you to sleep in an unfamiliar environment, and insurance companies may require additional approval for this option.
Home sleep studies, on the other hand, allow you to sleep in the comfort of your own home while a small monitor collects data. These studies are typically used to diagnose sleep apnea and track breathing parameters such as pauses in breathing, absence of breathing, breathing effort, and depth of breathing. They are more convenient, cost-effective, and can provide a more accurate reading of your typical sleep patterns. However, they do not capture the full range of data that an overnight sleep study in a lab can provide, and they may not be suitable for individuals with conditions other than sleep apnea. Additionally, home sleep studies may not be recommended for those who live alone or are not technologically adept enough to set up the equipment.
Both options have their advantages and are suited to different situations. In-lab sleep studies provide a more comprehensive evaluation but may be less convenient, while home sleep studies offer comfort and convenience but may not be suitable for diagnosing all types of sleep disorders. Ultimately, the decision of which type of sleep study to undergo should be made in consultation with a medical professional, who can recommend the most appropriate option based on your specific needs and circumstances.

Sleep studies are non-invasive and monitor various functions to diagnose sleep disorders
Sleep studies are a common way to diagnose sleep disorders. They are non-invasive and monitor various functions of the body to determine whether a patient has a sleep disorder. While there are some differences between in-lab and at-home sleep studies, both are used to diagnose sleep disorders.
In-Lab Sleep Studies
In-lab sleep studies, also known as polysomnography (PSG), are overnight exams that take place in a sleep centre or hospital. A sleep technician monitors the patient throughout the night, tracking a variety of functions, including:
- Heart rate
- Breathing
- Eye movement
- Brain activity
- Muscle tone
- Respiratory effort
- Airflow
- Blood oxygen levels
- Body position
- Leg and arm movements
At-Home Sleep Studies
At-home sleep studies, also known as Home Sleep Apnea Tests (HSAT), are a more convenient option for patients. They allow patients to sleep in their own beds while a small monitor collects data. At-home sleep studies are usually reserved for cases where sleep apnea is strongly suspected or for follow-up testing after treatment. These studies typically monitor:
- Breathing
- Heart rate
- Movement of the breathing-related muscles in the chest and belly
A sleep study is a diagnostic test used to diagnose or rule out health issues. They are usually recommended when a patient is displaying symptoms of conditions that affect sleep. Sleep studies can help diagnose many sleep disorders, including:
- Sleep apnea
- Periodic limb movement disorder
- Restless legs syndrome
- Narcolepsy
- Insomnia
- REM sleep behaviour disorder
- Nocturnal panic attacks
- Sleepwalking
- Night terrors
Whether or not you need a referral for a sleep study depends on your insurance provider. Some insurance companies require a referral from a physician and, in some cases, authorisation from your health insurance company. It is best to check with your insurance provider to see what their specific requirements are.

Sleep specialists treat and diagnose sleep disorders
Sleep specialists diagnose and treat sleep disorders. They can include psychiatrists, psychologists, neurologists, paediatricians, otorhinolaryngologists, dentists, oral and maxillofacial surgeons, and respiratory therapists. Sleep specialists work in private practice, hospitals, or sleep centres.
Sleep specialists train in internal medicine, psychiatry, paediatrics, or neurology during their residency. After completing their residency, they finish a fellowship programme in sleep medicine and get their board certification from the American Board of Sleep Medicine.
A sleep study is a non-invasive, overnight exam that is used to diagnose sleep disorders. The test measures specific sleep characteristics and parameters to determine if a patient has sleep disorders such as sleep apnea, periodic limb movement disorder, narcolepsy, restless legs syndrome, insomnia, and REM sleep behaviour disorder. There are two types of sleep studies: polysomnography or in-lab (PSG) and home sleep apnea test (HSAT).
To schedule a sleep study, you will need a referral from a physician and, in some cases, authorisation from your health insurance company. Sleep lab staff can sometimes get approval from your insurance company on your behalf. The sleep study referral is for you to start seeing a sleep medicine specialist. The specialist will give you a consultation first and then schedule your sleep study.

Sleep studies are covered by insurance
Sleep studies are often covered by insurance if they are deemed medically necessary. The cost of a sleep study can range from less than $500 to more than $10,000, depending on insurance coverage and whether it is an in-lab or at-home study. Out-of-pocket expenses for a sleep study can range from a few hundred to a few thousand dollars.
Medicare covers 80% of the cost of medically necessary sleep studies and PAP titration after the deductible is met, including in a hospital or an approved sleep clinic. To qualify for Medicare coverage, a person must have a doctor's referral for testing based on symptoms of a sleep disorder such as sleep apnea, narcolepsy, or a parasomnia.
Medicaid also covers sleep studies if a person has symptoms of a relevant sleep disorder and undergoes the test in an approved facility. Additionally, Medicaid covers at-home sleep studies for suspected obstructive sleep apnea.
Private insurance providers may have different conditions for coverage. It is important to confirm that the chosen sleep center is covered by the insurance plan before booking a sleep study. As with most medical treatments, a person may be responsible for paying a deductible if they have not yet reached their limit. If the plan has a high deductible or if a person does not have insurance, they may want to consider the costs of different sleep clinics.
The cost of an in-lab sleep study, also known as polysomnography, typically ranges from $1,000 to over $10,000, depending on insurance coverage. This type of sleep study is more expensive than an at-home study because it involves an overnight stay in a lab with technicians monitoring the patient. The sleep study measures various parameters such as brain waves, breathing, heart rate, and eye movement to diagnose sleep disorders.
At-home sleep studies, on the other hand, range from $150 to around $1,000 or more. They are generally much cheaper than in-lab studies because they use less equipment, do not involve an overnight stay, and do not require technicians to be present. However, at-home studies may not be suitable for people with heart or lung conditions or those with other co-occurring sleep disorders.
