What Medicare Covers for Inspire

Medicare Part B covers Inspire, a surgically implanted device that treats obstructive sleep apnea, but only under specific conditions. You must have moderate to severe obstructive sleep apnea, have tried and failed a CPAP machine or similar therapy, and have a sleep study showing the device is appropriate for you. The coverage includes the surgical implantation, the device itself, and follow-up visits to adjust the settings.

The key requirement is that your doctor must document your CPAP failure in your medical record before Inspire is considered. Medicare does not cover the device if you have not given CPAP or similar therapy a genuine trial first. This means wearing the mask consistently for at least four weeks, though many insurers and Medicare reviewers look for longer use before approving Inspire.

Coverage varies slightly depending on whether you have Original Medicare (Part A and B) or a Medicare Advantage plan. Original Medicare follows the national coverage decision set by the Centers for Medicare & Medicaid Services (CMS). Medicare Advantage plans must cover at least what Original Medicare covers, but some plans may have additional requirements or different approval timelines.

Key Takeaways

  • Medicare Part B covers Inspire surgery and the device if you have moderate to severe sleep apnea and have tried CPAP therapy first without success.
  • Your doctor must document at least four weeks of CPAP use (and often longer) before Medicare will review your Inspire request.
  • You will need a sleep study showing obstructive sleep apnea and confirmation that Inspire is medically appropriate for your specific condition.
  • Original Medicare typically covers 80 percent of the approved amount after you meet your Part B deductible; your out-of-pocket cost depends on your plan and whether your surgeon is in-network.
  • Medicare Advantage plans have their own approval processes and may require prior authorization before your surgery is scheduled.

How to Confirm Coverage Before Surgery

Do not assume Medicare will cover Inspire based on your diagnosis alone. Contact your plan directly — either Medicare (1-800-MEDICARE) if you have Original Medicare, or your Medicare Advantage plan's customer service number — and ask whether Inspire is covered under your specific plan. Have your doctor's name, your sleep apnea diagnosis, and your CPAP history ready when you call.

Your surgeon's office can also check coverage on your behalf. Many sleep medicine practices have staff who handle insurance verification and can tell you what Medicare requires before they schedule your surgery. This step saves time and prevents surprises after the procedure.

Ask specifically about prior authorization. Some Medicare Advantage plans require written approval from the plan before your surgeon operates. If your plan requires it and your surgeon proceeds without it, you may be responsible for the full cost. Original Medicare does not require prior authorization for Inspire, but your surgeon's office should still verify that your medical records meet the coverage criteria.

What You Pay Out of Pocket

With Original Medicare, you pay your Part B deductible (the amount changes yearly) and then 20 percent of the approved amount for the surgery and device. The remaining 80 percent is covered by Medicare. The total approved amount varies by region and surgeon, but Inspire surgery typically costs between $20,000 and $30,000 before insurance.

If your surgeon is out-of-network, you may owe more. Medicare pays based on what it considers reasonable for your area; an out-of-network surgeon can charge more, and you are responsible for the difference. Always confirm your surgeon is in-network with Medicare before scheduling.

Medicare Advantage plans have different cost structures. Some charge a copay for surgery, others charge coinsurance (a percentage of the cost), and some have no separate charge if the procedure is deemed medically necessary. Your plan documents or customer service line will tell you your exact responsibility. Many Advantage plans also have an out-of-pocket maximum that limits your total spending in a year.

The CPAP Trial Requirement

Medicare requires documented evidence that you have used CPAP or a similar therapy (such as BiPAP or APAP) without adequate benefit before approving Inspire. This is not a suggestion — it is a hard requirement. Your doctor must show in your medical record that you wore the mask for a reasonable period, typically at least four weeks, and that your sleep apnea symptoms did not improve enough to make the therapy work for you.

Inadequate benefit means different things to different reviewers. Some focus on whether your apnea-hypopnea index (AHI) improved; others look at whether you tolerated the mask and used it regularly. If you stopped CPAP because you could not tolerate the mask or hated wearing it every night, that counts as failure for Medicare's purposes. If you never really tried it or used it only a few nights, Medicare will likely deny Inspire coverage and ask you to try again.

If you are considering Inspire, discuss the CPAP trial with your sleep doctor now. Ask them to document your experience carefully in your chart, including how many nights per week you used the device, what problems you had, and why CPAP did not work for you. This record becomes your evidence when Medicare reviews your Inspire request.

Sleep Study Requirements

You must have a recent sleep study showing moderate to severe obstructive sleep apnea. Medicare defines moderate as an AHI (apnea-hypopnea index) of 15 to 30 events per hour; severe is 30 or more. If your sleep study shows mild sleep apnea (AHI below 15), Medicare will not cover Inspire, regardless of your symptoms.

The sleep study does not have to be brand new. Medicare will accept a study from within the past two years, though some reviewers prefer a more recent one if your condition may have changed. If you had your sleep study years ago, your doctor may recommend a new one to confirm your current severity and rule out other conditions.

Your sleep study should also show that you have obstructive sleep apnea specifically, not central sleep apnea or mixed apnea. Inspire is designed for obstructive apnea, where the airway collapses during sleep. If your study shows primarily central apnea (where your brain does not signal your muscles to breathe), Inspire is not appropriate and Medicare will not cover it.

Original Medicare Versus Medicare Advantage

Original Medicare (Part A and B) follows the national coverage decision for Inspire set by CMS. If you meet the criteria — moderate to severe sleep apnea, CPAP failure, and a recent sleep study — Original Medicare will cover the procedure at 80 percent after your deductible. There is no prior authorization step, though your surgeon's office may verify your coverage before scheduling.

Medicare Advantage plans must cover Inspire at least as generously as Original Medicare, but they can add their own requirements. Some Advantage plans require prior authorization, meaning your doctor must submit paperwork and get approval before your surgery. Others may require you to try a different therapy first, or may limit which surgeons you can use. Check your plan documents or call your plan's customer service to learn what it requires.

If you switch between Original Medicare and a Medicare Advantage plan, or vice versa, coverage rules may change. If you are thinking about Inspire, confirm your current plan's coverage before making any decisions. Changing plans mid-year is usually not possible, so understanding your coverage now prevents problems later.

What Happens After Surgery

Medicare covers follow-up visits to program and adjust your Inspire device. These visits typically happen in the weeks and months after surgery as your surgeon fine-tunes the settings to reduce your apnea events while keeping you comfortable. The device uses a small remote control to adjust the stimulation level, and your surgeon helps you find the right setting for your body.

Ongoing device maintenance and battery replacement are also covered by Medicare. Inspire devices have a battery that lasts about nine to ten years, after which the device must be replaced. When the battery is near the end of its life, your surgeon will schedule a replacement procedure, and Medicare will cover it the same way it covered the original implant.

If you have a Medicare Advantage plan, confirm that follow-up visits and future device replacement are covered before your initial surgery. Most plans cover these services, but it is worth verifying so you know what to expect.

Frequently Asked Questions

Do I have to try CPAP for a certain number of months before Medicare will cover Inspire?

Medicare requires documented CPAP use for at least four weeks, but many reviewers look for longer use — often three to six months — to show you gave it a genuine trial. Your doctor's notes matter most. If you used CPAP consistently for four weeks and it clearly did not work for you, that may be enough. If you used it sporadically or for only a few nights, Medicare will likely ask you to try longer.

What if my sleep apnea is mild but my symptoms are severe?

Medicare bases coverage on your sleep study results (your AHI number), not on how bad your symptoms feel. If your AHI is below 15, Medicare considers your apnea mild and will not cover Inspire, even if you feel exhausted during the day. You would need to explore other treatment options with your doctor or consider paying for Inspire out of pocket.

Can I get Inspire if I have not tried CPAP at all?

No. Medicare requires documented CPAP failure as a condition of coverage. If you have never tried CPAP, Medicare will deny Inspire coverage and ask you to try CPAP first. Your doctor can help you get your free guide with CPAP and document your experience over several weeks or months.

Will my Medicare Advantage plan cover Inspire the same way Original Medicare does?

Medicare Advantage plans must cover Inspire at least as well as Original Medicare, but they may have different approval processes, prior authorization requirements, or cost-sharing amounts. Call your plan directly to learn what it requires and what you will owe out of pocket.

What if my surgeon is out of network with Medicare?

Medicare will still pay its approved amount (80 percent after your deductible), but an out-of-network surgeon can charge more than that approved amount. You would owe the difference. Always confirm your surgeon is in-network with Medicare before scheduling surgery to avoid unexpected bills.
