Sleep Study Requirements for Sleep Apnea Treatment

What You Need to Know Before Starting Oral Appliance Therapy

What is a sleep study?

Why is a Sleep Study Required?

A sleep study is an essential step in diagnosing sleep apnea and determining the most appropriate treatment. While symptoms such as snoring, fatigue, or poor sleep may raise concern, a sleep study is the only way to confirm a diagnosis and measure the severity of sleep apnea.

Before oral appliance therapy can be prescribed, a documented sleep study is required for both medical safety and insurance coverage.


What are the Different Types of Sleep Studies?

There are 2 common types of sleep studies used to diagnose sleep apnea.

Home Sleep Test (HST)

A home sleep test is performed in your own bed using a small, portable monitoring device.

Home sleep tests:

  • Are commonly used for suspected obstructive sleep apnea

  • Measure breathing patterns and oxygen levels

  • Are convenient and comfortable for many patients

  • Are often covered by medical insurance

What If You Already Have a Sleep Study?

If you have already completed a sleep study:

  • We can review your existing results

  • In many cases, repeat testing is not required

  • Insurance companies may require the study to be recent

Dr. Ola and our team can help determine whether your existing sleep study meets current requirements.

In-Lab Sleep Study (Polysomnography)

An in-lab sleep study is conducted overnight in a sleep center.

In-lab studies:

  • Provide the most detailed sleep data

  • Are used for complex cases or when other sleep disorders are suspected

  • Are monitored by trained technicians

Your medical provider will determine which type of study is most appropriate.


What Does a Sleep Study Measure?

A sleep study evaluates several important factors, including:

  • Breathing interruptions

  • Oxygen levels

  • Heart rate

  • Sleep stages

  • Body position during sleep

One key result from the study is the Apnea-Hypopnea Index (AHI), which measures how many breathing interruptions occur per hour of sleep.

Why Is a Sleep Study Required for Oral Appliance Therapy?

A sleep study is required to:

  • Confirm the diagnosis of obstructive sleep apnea

  • Determine if oral appliance therapy is appropriate

  • Establish medical necessity for treatment

  • Meet insurance requirements for coverage

  • Allow proper monitoring of treatment effectiveness

Oral appliance therapy is a medical treatment, and it must follow established sleep medicine guidelines.


What If You’ve Never Had a Sleep Study?

If you have symptoms of sleep apnea but have never completed a sleep study, we can:

  • Coordinate with your medical provider

  • Help guide you toward appropriate testing

  • Explain next steps clearly and simply

The process is often easier than patients expect.


What Happens After the Sleep Study?

Once a sleep study confirms obstructive sleep apnea:

  • A treatment plan is recommended by your medical provider

  • Oral appliance therapy may be considered

  • Medical insurance coverage can be evaluated

  • Treatment effectiveness can be monitored

For patients who cannot tolerate CPAP, or prefer a more comfortable alternative, oral appliance therapy may be an effective option.

Ready to Take the Next Step?

If you have symptoms of sleep apnea or already have a sleep study, a consultation can help determine whether oral appliance therapy is right for you.


A sleep study is a medical test that monitors your breathing, oxygen levels, heart rate, and sleep patterns while you sleep.

The purpose of the study is to:

  • Confirm whether sleep apnea is present

  • Determine how severe it is

  • Guide appropriate treatment options

Sleep studies are ordered by a medical provider, such as a sleep physician or primary care provider.
