Scheduling a sleep study starts with your doctor. A healthcare provider must order the test before you can book one, so your first step is making an appointment with your primary care physician or requesting a referral to a sleep specialist. From there, the process involves choosing the right type of test, navigating insurance requirements, and preparing for the study itself.
Start With Your Doctor
You cannot schedule a sleep study on your own. Your doctor or another healthcare provider must order it. This is both a medical requirement and an insurance one, since most plans won’t cover a study without a physician’s order.
Before your appointment, keep a log of your symptoms for at least a week or two. Note things like how often you wake up at night, whether your partner has noticed snoring or gasping, how tired you feel during the day, and any morning headaches. This gives your doctor concrete information to work with when deciding whether a sleep study is warranted and which type to order. If your primary care doctor agrees a study is needed, they may refer you to a sleep medicine specialist, or they may order the test directly and send you to a local sleep lab or mail you a home testing kit.
In-Lab Study vs. Home Sleep Test
There are two main options, and your doctor will recommend one based on your symptoms and medical history.
A home sleep apnea test is a simplified version you do in your own bed. It primarily monitors your breathing, not your brain activity or sleep stages. Because it doesn’t measure brain waves, it can’t precisely track how long you actually slept or how you cycled through sleep stages. Instead, it estimates breathing interruptions during the total recording time. That said, for people with signs of obstructive sleep apnea, home tests accurately identify the condition about 90% of the time. Your doctor is most likely to recommend this option if you appear to have moderate to severe obstructive sleep apnea with no other complicating medical conditions.
An in-lab polysomnography is a more comprehensive overnight study conducted at a sleep center. Technicians attach sensors that track your breathing, heart rate and rhythm, brain waves, eye movements, and sleep stages throughout the night. This is the appropriate choice if you have cardiovascular disease, respiratory conditions, severe insomnia, a neuromuscular condition, or if you use opioids. Doctors also recommend in-lab studies when a home test comes back negative or inconclusive despite a strong suspicion of sleep apnea.
Dealing With Insurance and Prior Authorization
Many insurance plans require prior authorization before they’ll cover a sleep study, particularly for in-lab polysomnography. The specifics vary by insurer. Among major private payers, most require prior authorization for in-lab studies. Home sleep apnea tests face fewer authorization hurdles: insurers like Aetna, Cigna, Humana, and UnitedHealthcare do not require prior authorization for home tests, though Anthem, Centene, and some Blue Cross Blue Shield plans do.
Your doctor’s office typically handles the prior authorization paperwork, but it’s worth confirming this when you schedule. Ask the office staff directly: “Will you submit the prior authorization, or do I need to call my insurance company?” Delays in authorization are one of the most common reasons sleep studies get pushed back, so follow up if you haven’t heard anything within a week or two.
Medicare covers sleep studies when ordered by a doctor, though it has its own requirements around documentation and written orders that your provider will need to meet.
What It Costs
Without insurance, home sleep tests typically run $150 to $1,000. In-lab studies cost significantly more, ranging from $1,000 to $10,000, with an average price around $3,000. With insurance, your out-of-pocket cost depends on your deductible, copay, and whether the sleep lab is in-network. Before your study, call both your insurance company and the sleep facility to get a cost estimate. Ask the facility if they offer payment plans if the out-of-pocket amount is high.
How to Prepare the Day Before
For an in-lab study, preparation is straightforward. Skip caffeine in the afternoon and evening before your study. That includes coffee, tea, cola, and chocolate. Avoid alcohol entirely that day. Don’t stop taking any prescription medications without talking to your sleep specialist first, but do make sure your specialist knows about everything you take, including over-the-counter cold medicines and pain relievers.
Pack an overnight bag as if you were staying at a hotel. Bring comfortable pajamas, a change of clothes for the morning, toiletries, and your medications. You can bring your own pillow if that helps you sleep more normally. Most sleep labs have private rooms with beds that are more comfortable than a hospital setting, and you’ll typically arrive in the evening and leave early the next morning.
For a home test, your doctor’s office or the sleep lab will give you the device along with instructions. You’ll attach a few sensors yourself before bed, usually a nasal cannula, a finger clip to measure oxygen levels, and a chest belt. The device records overnight and you return it the next day or mail it back.
Getting Your Results
A sleep specialist scores and interprets the data from your study. You should expect to hear back within a few days, though the timeline varies by facility. It’s a good idea to ask when you’ll receive results on the night of your study so you know what to expect. The follow-up appointment is where your doctor will walk you through the findings, explain whether you have a sleep disorder, and discuss treatment options if needed. If your home test was inconclusive but your doctor still suspects sleep apnea, they’ll likely schedule an in-lab study as a next step.
