Sleep Study & Sleep Apnea Treatment Costs by Country

Sleep apnea care is really two separate purchases. First comes the diagnosis, a sleep test that can happen in a lab or in your own bed. Then comes treatment, most often a CPAP machine plus a steady stream of masks, tubing and filters for as long as you use it. The two can be bought in different places, from different sellers, under different rules. Getting the order wrong is how people pay twice.

Two kinds of sleep test, two kinds of bill

In-lab polysomnography

You sleep overnight in a sleep center while a technician monitors many signals, typically including brain activity, breathing, oxygen levels, heart rhythm and leg movements. The bill usually reflects four things: the facility and bed, the overnight technician, scoring of the recording, and a physician's interpretation. In the US these may come from different billing entities, much like a hospital procedure.

Some labs run a split-night study, diagnosing in the first half of the night and testing CPAP pressure in the second. Others book a separate titration night. A second night is a second bill, so ask which approach the lab uses before comparing quotes.

Home sleep apnea testing

A home test uses a smaller set of sensors, usually focused on breathing and oxygen. You collect the device or receive it by post, wear it overnight and return it. The cost is mainly the device use and the physician's interpretation, without a facility or overnight technician.

Home testing is cheaper to deliver, but it is not a substitute for a lab study in every case. Your clinician decides which test suits your symptoms and health history. If a home test is inconclusive, you may end up paying for a lab study as well, which is worth knowing before you choose the cheapest test available.

Treatment: a device and a supply chain

CPAP (continuous positive airway pressure) is the most common treatment for obstructive sleep apnea. Its cost comes in layers:

Alternatives such as custom oral appliances made by dentists, or surgery on the nose, palate or airway, have their own cost structures. Airway and nasal procedures are covered in our ENT surgery cost guide.

How insurance shapes the CPAP bill: the Medicare example

Medicare's published rules show why the insured price of CPAP is not a simple sticker price. According to Medicare.gov (accessed October 2026):

• Medicare may cover a 12-week trial of CPAP therapy, including devices and accessories, after an obstructive sleep apnea diagnosis.
• Coverage can continue after the trial if you meet with your doctor in person and they document that you meet certain conditions and the therapy is helping.
• Medicare pays the supplier to rent the machine for 13 months if you use it continuously, after which you own it.
• After the Part B deductible, you pay 20% of the Medicare-approved amount, if the supplier accepts assignment. Masks, tubing and similar supplies are covered with the same 20% share.
• If a rental supplier does not accept assignment, you may have to pay the full cost upfront and wait for Medicare's portion.

Private plans have their own rules, often with similar ideas: a trial period, usage checks and rent-to-own arrangements. The lesson for budgeting is that your real CPAP cost is spread over many months and depends on keeping up with the plan's conditions. If your deductible is high, compare that spread-out cost with buying outright; our article on the deductible trap shows how to run that comparison.

The order matters: test, prescription, coverage

People who price a sleep study abroad usually do so because the test looks expensive at home. Before booking, ask three questions of your insurer or the equipment supplier you would use at home:

1. Will you accept a sleep study performed and interpreted outside the country, and in what language and format?
2. Will you need a prescription or face-to-face evaluation from a clinician licensed where I live?
3. If I buy a machine abroad, will you still cover masks and supplies for it?

If the answers are no, a cheap test abroad may still leave you paying for a second test at home to unlock coverage. If you are paying cash for everything anyway, the test abroad may simply be cheaper. Our guide to what insurance covers versus what you pay abroad covers the wider coverage question.

Buying a CPAP machine abroad

Machines are made by a handful of global manufacturers, so the device itself may be the same model at home and abroad. The differences are in the paperwork and the support:

• Warranty: ask whether the manufacturer honors it in your home country.
• Power: check the voltage range and plug type, and whether you need an adapter.
• Supplies: make sure your mask and tubing are sold where you live.
• Data: if your clinician wants usage reports, confirm the machine's data can be read at home.
• Settings: leave with the prescribed pressure settings in writing.

A first-year budget for sleep apnea care

Instead of comparing one test price with another, build a first-year total. It captures the costs that a single quote leaves out:

1. Consultation with the clinician who orders the test, if billed separately.
2. The sleep test, home or lab, plus a titration night if the lab books one.
3. A repeat or upgraded test, if a home study turns out to be inconclusive. Put it in as a possibility, not a certainty.
4. The machine, either as a purchase price or as your share of the rental months that fall in the first year.
5. Starter supplies and replacements: masks, cushions, tubing and filters at the replacement schedule your supplier or plan uses.
6. Follow-up: the visit or visits that check whether the therapy is working, which may also be what keeps insurance coverage going.
7. Travel, if any of the above happens abroad, including a return visit if settings need adjusting.

Run the total twice, once with insurance and once as cash, and keep both. The cheaper path is often different in year one than in year two, because the test and the machine are front-loaded and supplies are not.

Comparing countries

We have not found a reputable source that compares sleep study or CPAP prices consistently across countries in 2026, so we do not publish a country table. The structure of the decision is the same everywhere: a sleep study abroad is most useful when you are already there for several weeks, can attend follow-up, and either pay cash at home or have confirmed your insurer will accept the result. Repeated titration nights, an inconclusive home test or a supplier who will not recognise a foreign prescription are the scenarios that erase the savings.
