How Much Does a Sleep Study Cost? What to Expect With and Without Insurance

What are the two types of sleep study, and how do their costs differ?

Home sleep apnea test (HSAT): A portable device you use in your own bed for one or more nights. It records breathing effort, airflow, and blood-oxygen levels. HSATs are appropriate when obstructive sleep apnea is the primary concern and no complicating medical factors are present 1Ref 1Kapur VK, Auckley DH, Chowdhuri S, et al. (2017).Clinical Practice Guideline for Diagnostic Testing for Adult Obstructive Sleep Apnea: An American Academy of Sleep Medicine Clinical Practice Guideline.AASM guideline specifying when home sleep apnea tests vs in-lab polysomnography are appropriate, including indications for each study type. Without insurance, they typically cost a few hundred dollars; cash prices often fall between $150 and $500 depending on the provider.

In-lab polysomnogram (PSG): A full overnight study at a sleep center where technicians monitor brain waves, eye movements, limb movements, breathing, oxygen, and heart rate simultaneously (CPT code 95810). PSGs are indicated when a complex disorder — narcolepsy, REM sleep behavior disorder, periodic limb movement disorder — is suspected, or when a home test has been inconclusive 1Ref 1Kapur VK, Auckley DH, Chowdhuri S, et al. (2017).Clinical Practice Guideline for Diagnostic Testing for Adult Obstructive Sleep Apnea: An American Academy of Sleep Medicine Clinical Practice Guideline.AASM guideline specifying when home sleep apnea tests vs in-lab polysomnography are appropriate, including indications for each study type. Without insurance, in-lab studies commonly range from several hundred to over $3,000 at hospital-based facilities.

How does insurance typically cover a sleep study?

Most major insurance plans cover sleep studies when they are medically necessary. Medicare Part B covers both home sleep tests and in-lab polysomnograms when ordered for a documented clinical reason, such as signs and symptoms of obstructive sleep apnea 2Ref 2Centers for Medicare & Medicaid Services (2024).LCD — Polysomnography and Other Sleep Studies (L36902).Medicare coverage criteria for in-lab polysomnography (CPT 95810) and home sleep apnea testing, including medical-necessity documentation requirements. After the annual Part B deductible, Medicare typically pays 80% and the beneficiary pays 20%.

Prior authorization is often required. Your clinician's office usually submits this request before the study is scheduled.

Your out-of-pocket cost depends on: - Whether your annual deductible has been met - Your copay or coinsurance rate for the facility type - Whether the sleep center is in-network — an in-network facility almost always costs less, sometimes dramatically

Hospital-based sleep centers often bill a separate facility fee on top of the professional interpretation fee, which can make them significantly more expensive than freestanding clinics.

What should you do before scheduling to avoid a surprise bill?

Call the member services number on the back of your insurance card before booking. Ask: - Is a sleep study covered under my plan, and does it require prior authorization? - Which sleep centers in my area are in-network? - What is my deductible, and how much have I met this year? - What will my estimated out-of-pocket cost be?

Sleep studies are typically billed under CPT code 95810 (in-lab PSG) or 95806 (home sleep test). Having these codes when you call can help you get a specific estimate 2Ref 2Centers for Medicare & Medicaid Services (2024).LCD — Polysomnography and Other Sleep Studies (L36902).Medicare coverage criteria for in-lab polysomnography (CPT 95810) and home sleep apnea testing, including medical-necessity documentation requirements.

What are your options if you do not have insurance or have a high deductible?

• Ask for a self-pay or cash price. Many sleep centers offer self-pay rates meaningfully lower than their standard billed rates.
• Consider telehealth-ordered home sleep tests. Direct-to-consumer or telehealth-ordered HSATs are often less expensive and can be arranged quickly. They evaluate for sleep apnea specifically and are not appropriate for all clinical situations 1Ref 1Kapur VK, Auckley DH, Chowdhuri S, et al. (2017).Clinical Practice Guideline for Diagnostic Testing for Adult Obstructive Sleep Apnea: An American Academy of Sleep Medicine Clinical Practice Guideline.AASM guideline specifying when home sleep apnea tests vs in-lab polysomnography are appropriate, including indications for each study type.
• Community health centers. Federally Qualified Health Centers (FQHCs) offer sliding-scale fees and may be able to refer you for a sleep study at reduced cost.
• Use HSA or FSA funds. Sleep studies qualify as eligible medical expenses for both health savings accounts (HSA) and flexible spending accounts (FSA), allowing you to pay with pre-tax dollars 3Ref 3Internal Revenue Service (2024).Publication 502: Medical and Dental Expenses.Sleep studies qualify as eligible medical expenses under IRS rules for HSA and FSA reimbursement.
