Your first stop for sleep apnea is usually your primary care doctor, who can screen your symptoms and refer you to a sleep specialist for testing. But depending on your situation, you might end up seeing several different types of providers, from sleep medicine physicians to dentists trained in oral appliance therapy to surgeons who address structural problems in your airway. Here’s how to navigate the options.
Start With Your Primary Care Doctor
A primary care physician is the most common entry point. They’ll ask about your symptoms, your sleep history, and how your bed partner describes your nighttime breathing. Expect questions about whether you stop breathing during sleep, how many times per night it happens, whether your sleep position or alcohol use makes things worse, and how severe your daytime sleepiness is.
Based on that conversation, most doctors refer you directly to a sleep center or sleep specialist for further evaluation. Some may have you fill out a standardized sleepiness questionnaire first, which scores your tendency to doze off during everyday activities like reading, watching TV, or sitting in traffic. A score above 10 on this scale suggests abnormal daytime sleepiness and strengthens the case for testing.
Sleep Medicine Specialists
A sleep medicine specialist is a physician who completed additional training in diagnosing and treating sleep disorders. These doctors come from a range of backgrounds: internal medicine, pulmonology, neurology, psychiatry, ear-nose-throat surgery, pediatrics, and anesthesiology can all lead to board certification in sleep medicine. The certification program is jointly administered by six different medical boards, which means sleep specialists approach the condition from different angles depending on their training.
A pulmonologist who specializes in sleep medicine, for example, may focus on how your breathing mechanics contribute to apnea, while a neurologist might pay closer attention to how your brain regulates sleep cycles. For most people, the specific background matters less than the sleep medicine certification itself. Your primary care doctor can point you to a sleep center staffed by board-certified sleep specialists.
Home Testing vs. In-Lab Sleep Studies
Once you’re connected with a sleep specialist, the next step is a sleep study. You’ll typically be offered one of two options: a home sleep test or an overnight study in a sleep clinic.
Home tests work well if your doctor suspects you have moderate to severe obstructive sleep apnea without other complicating health problems. You wear a small sensor for one night, and the data is reviewed by a physician. These tests cost between $150 and $1,000, making them significantly cheaper than in-lab alternatives.
An in-lab polysomnography is more comprehensive. Technicians monitor your brain waves, eye movements, heart rhythm, oxygen levels, and muscle activity throughout the night. This is the better choice if you have cardiovascular disease, respiratory conditions, severe insomnia, or use opioids, since those factors can complicate a diagnosis. In-lab studies average around $3,000 but can range from $1,000 to over $10,000 depending on the facility and your insurance. If a home test comes back negative or inconclusive despite strong suspicion of sleep apnea, your doctor will generally recommend following up with an in-lab study.
Telehealth and Online Sleep Clinics
Several online services now offer a streamlined path from screening to treatment. The typical process involves filling out an assessment, meeting with a doctor virtually, completing an at-home sleep test, and then reviewing results in a follow-up video visit. If you meet the diagnostic criteria for obstructive sleep apnea, the doctor can prescribe a CPAP or similar device and connect you with a sleep coach to plan your next steps.
This route works best for straightforward cases of obstructive sleep apnea in otherwise healthy people. If your situation is more complex, involving other sleep disorders, heart disease, or potential need for surgery, an in-person specialist is a better fit.
Dentists Trained in Sleep Apnea
Dentists play a growing role in both screening and treating obstructive sleep apnea. Because they see you twice a year and examine your mouth and jaw structure closely, they’re often the first to notice warning signs like a narrow palate, a crowded airway, or tooth grinding linked to disrupted breathing.
Beyond screening, dentists with specialized training can provide oral appliance therapy. This involves a custom-fitted device worn at night that repositions your lower jaw slightly forward, keeping the airway open. It’s a common alternative for people who can’t tolerate CPAP. The American Academy of Dental Sleep Medicine certifies dentists specifically for this treatment, and their directory is a good place to find a qualified provider. These dentists work alongside your sleep physician rather than replacing them: you still need a formal sleep study and diagnosis before starting oral appliance therapy.
ENT Surgeons for Structural Problems
An ear, nose, and throat specialist (otolaryngologist) enters the picture when anatomical issues contribute to your sleep apnea, or when other treatments haven’t worked. The evaluation is thorough: the surgeon examines your nasal airway, the soft palate area, throat walls, tongue base, and the skeletal structure of your face to identify where your airway collapses during sleep.
Common structural problems include a deviated septum, enlarged turbinates (tissue inside the nose that can swell and block airflow), and nasal valve dysfunction. Long-term nasal obstruction can also reshape facial structures over time, creating a narrow, high-arched palate with a relatively large tongue and excess soft tissue, a pattern associated with chronic mouth breathing.
Surgical options depend on where the obstruction occurs. Soft palate procedures work best when collapse happens primarily in that area. For obstruction behind the tongue, a newer option called upper airway stimulation uses an implanted device to keep the airway open, though candidates need to meet specific criteria: a BMI of 32 or below and an apnea severity index between 15 and 65 events per hour. More extensive jaw advancement surgery is reserved for moderate to severe cases, especially when collapse involves the side walls of the throat or when soft tissue surgery alone is unlikely to succeed. If you’ve been told your CPAP isn’t working because of nasal obstruction, an ENT evaluation can determine whether fixing the nasal problem would improve your tolerance.
What Insurance Typically Covers
Most insurance plans cover sleep studies when there’s documented clinical suspicion of sleep apnea. Your doctor’s notes about symptoms, sleepiness scores, and risk factors build the case for coverage. Apnea severity is measured by how many times per hour your breathing stops or becomes dangerously shallow: 15 or more events per hour qualifies as moderate, and 30 or more is severe.
Home sleep tests, given their lower cost, are often the first option insurers approve. In-lab studies may require prior authorization, especially if you don’t have complicating medical conditions. CPAP equipment and oral appliances are generally covered once you have a confirmed diagnosis, though your plan may require you to demonstrate consistent use of the device before continuing coverage. Check with your insurer about specific requirements before scheduling a study, since policies vary widely on deductibles, copays, and which facilities are in-network.
