The four major treatment pathways for obstructive sleep apnea

Most sites explaining your options are selling one of them. A CPAP retailer explains why masks are the gold standard. A dental practice explains why appliances are more comfortable. A device manufacturer explains why an implant is permanent.

This page does something narrower and, we think, more useful: it describes what each of the four main pathways physically involves, what it costs, and how insurance treats it. Several other approaches — positional therapy, weight management, myofunctional therapy — are covered at the end, because they are usually used alongside one of these rather than instead of one. It does not tell you which works better, because that depends on your anatomy, your severity, and your tolerance — and it’s a question for the clinician who has your sleep study, not a website.

1 · PAP therapy

What it is. A bedside machine pushes pressurised air through a tube into a mask, holding your airway open. CPAP delivers one fixed pressure. APAP adjusts within a range. Bilevel uses separate inhale and exhale pressures.

What it asks of you. Wearing a mask every night, indefinitely. This is the whole difficulty. The therapy works when it’s used, and the most common reason it isn’t used is a mask that doesn’t fit properly — which is a solvable equipment problem far more often than people are told.

How it’s covered. As durable medical equipment. Medicare rents the machine for an initial period, then requires two things to keep paying: an in-person re-evaluation with your practitioner between day 31 and day 91, and documented adherence — use of at least four hours a night on 70% of nights during any consecutive 30-day period in the first three months. That’s 21 nights out of 30. Most commercial plans use similar rules.

Practical cost. The machine is usually rented then owned. The ongoing cost is supplies: cushions monthly, headgear and tubing on a schedule. Nobody quotes you the five-year number up front.

Where it goes wrong. Mask leak, pressure intolerance, dry mouth, claustrophobia. All four have equipment answers, and all four are also the reason people quit before trying them.

2 · Oral appliance therapy

What it is. A custom device, made from impressions of your teeth, that holds your lower jaw forward while you sleep. Not a night guard, and not the boil-and-bite device sold online — those are a different object and are generally not covered.

What it asks of you. Wearing a dental appliance nightly, plus a fitting period. The jaw is advanced in small increments over weeks or months until it works. Some people get jaw soreness or bite changes over time, which is why follow-up matters.

How it’s covered. This is the one people get wrong, and it’s expensive to get wrong. Sleep apnea is a medical diagnosis, so the appliance is billed as medical durable equipment, not as a dental procedure. Practices that bill it to your dental plan run it against an annual maximum of maybe $1,500 across everything.

Medicare’s requirements: an in-person evaluation by a physician or equivalent practitioner before the sleep test, a qualifying sleep test, an order written after the practitioner reviews it, and the device provided by a licensed dentist. The dentist also needs to be enrolled as a Medicare equipment supplier.

Practical cost. Cash quotes commonly land around $3,500. Billed correctly to medical, your share is deductible and coinsurance instead. Same device.

3 · Surgery and implants

What it is. Several distinct things, not one. Hypoglossal nerve stimulation implants a device that activates the tongue muscle in time with your breathing. Other procedures modify soft tissue or skeletal structure to reduce airway collapse.

What it asks of you. A surgical procedure, recovery, and in the case of an implant, a device you keep. Unlike a mask or an appliance, most of this isn’t reversible.

How it’s covered. Almost always with prior authorization, and typically only after documented failure or intolerance of PAP therapy. That sequence matters practically: if you abandon CPAP without it being documented, you may have made the surgical route harder to get covered. Tell your clinician it isn’t working rather than simply stopping.

Practical cost. Substantial, and highly variable by procedure and facility. Coverage is the determining factor rather than a factor.

Who it suits is a clinical question with real criteria, and it’s not one we’ll answer here. Ask a sleep physician and an ENT surgeon, and ask both what happens if it doesn’t work.

4 · Medication

What it is. Newly possible. Tirzepatide, sold as Zepbound, is approved for moderate-to-severe obstructive sleep apnea in adults with obesity — the only medication with an FDA approval specifically for OSA. It’s a weekly injection and works substantially through weight reduction.

What it asks of you. An ongoing prescription, ongoing cost, and side effects that are commonly gastrointestinal. Because the mechanism runs through weight, the honest expectation is that stopping the medication means the condition tracks back.

How it’s covered. This is the hard part. Medicare Part D can cover it for OSA in someone with obesity, but not for weight loss alone. Commercial coverage is volatile — formulary placement has changed mid-stream, and prior authorization is close to universal.

Practical cost. List price is roughly $1,000 a month. With coverage, typically far less.

Other approaches you'll hear about

These are real and can matter, but they are generally used alongside one of the four above rather than as a replacement. We treat them separately because the evidence, the cost, and the coverage picture all work differently.

Positional therapy. For some people, breathing events concentrate heavily when sleeping on the back. Devices and techniques that discourage back-sleeping exist, ranging from wearable trainers to simple improvisations. Whether it applies to you depends on what your sleep study showed about position.

Weight management. Weight is one of the strongest modifiable risk factors in obstructive sleep apnea, which is also the mechanism the approved medication works through. Covered as its own benefit category rather than as apnea treatment, which complicates the paperwork.

Myofunctional therapy. Exercises targeting the tongue and upper airway muscles. Low cost and low risk; typically not covered, and usually discussed as an adjunct.

Treating what’s blocking your nose. Nasal obstruction doesn’t cause obstructive sleep apnea, but it can make PAP therapy much harder to tolerate. If you can’t breathe through your nose, that’s worth addressing regardless of which pathway you choose.

None of these are things to substitute for treatment on your own. They’re things to raise with your clinician as additions.

These are not four competing products

The framing that gets lost in most coverage: combination is normal.

A medication that reduces severity may leave you still needing PAP, at a lower pressure that’s easier to tolerate. An oral appliance may be what you use when travelling and PAP what you use at home. Surgery may reduce severity without eliminating the need for anything else.

The drug trials specifically studied people who were already using PAP — one of the two enrolled PAP users. The question wasn’t only “instead of,” it was also “alongside.”

What actually decides it

Four things, in roughly this order:

Your severity and anatomy. Determined by your sleep study, not preference.

What you’ll actually use. The most effective treatment you abandon is worse than the second-most-effective one you keep using. This is not a small point — it’s the central one.

What your insurance will cover, and in what order. Many plans require PAP to be tried first. Knowing that before you start saves a denial later.

What you’d have to keep doing. A mask every night, an appliance every night, an injection every week, or a procedure once. Those are genuinely different commitments and the right answer depends on which you can live with.

This page describes how these treatments work and how they’re paid for. It doesn’t compare how well they work, and it isn’t medical advice. Which is appropriate for you depends on your sleep study and your anatomy — questions for the clinician managing your care.
