If you rely on oxygen therapy, understanding how much does Medicare pay for portable oxygen concentrators can help you plan for healthcare costs and avoid unexpected expenses.
Medicare Part B covers medically necessary oxygen equipment through an approved rental program, but beneficiaries are still responsible for certain costs.
This guide explains Medicare’s payment structure, eligibility requirements, rental rules, and what you can expect to pay out of pocket in 2026.
1. Does Medicare Cover Portable Oxygen Concentrators?
Yes, Medicare Part B covers oxygen therapy and durable medical equipment (DME) when it is medically necessary and prescribed by a doctor.
This includes oxygen systems such as stationary units and portable oxygen equipment provided through a Medicare-approved supplier.
However, Medicare does not specifically guarantee coverage of portable oxygen concentrators (POCs). Instead, coverage focuses on oxygen therapy needs, and suppliers may provide different types of equipment based on availability and contract rules.
To qualify, patients must meet medical eligibility requirements, and equipment is usually provided through a rental arrangement rather than a direct purchase.
2. How Much Does Medicare Pay For Portable Oxygen Concentrators?
Medicare Part B generally pays 80% of the Medicare-approved rental amount. The beneficiary pays the remaining 20% after meeting the annual Part B deductible.
Medicare provides this coverage strictly through a monthly rental arrangement rather than purchasing the device outright.
Understanding Medicare Part B coverage
Medicare Part B covers portable oxygen concentrators (POCs) as Durable Medical Equipment (DME).
To qualify, your doctor must certify you have a severe lung disease and that your blood oxygen level drops to 88% or lower during rest, sleep, or exercise.
Both your doctor and your equipment supplier must be enrolled in Medicare. When approved, the coverage includes the device rental and essential accessories like tubing, cannulas, and batteries.
Breaking down the 36-month rental rule
Understanding how much does Medicare pay for portable oxygen concentrators also requires knowing how the rental system works.
Medicare oxygen equipment operates on a 36-month rental contract. You pay your 20% coinsurance monthly for 36 months, after which the rental fees stop because the supplier has received maximum payment.
The supplier must then let you use the equipment for an additional 24 months (reaching a 5-year total lifespan) at no extra rental charge. However, you may still pay a 20% coinsurance for routine maintenance during this extended period.
Out-of-pocket costs and deductibles
You must pay your annual Part B deductible before Medicare coverage kicks in. After that, you are responsible for the 20% coinsurance of the Medicare-approved regional rental rate.
To avoid extra costs, ensure your supplier “accepts assignment,” meaning they agree to Medicare’s approved payment amount. If you have a Medicare Advantage or Medigap plan, your remaining out-of-pocket costs may be lower or capped.
3. Who Is Eligible For Medicare Oxygen Coverage?
To determine your total out-of-pocket costs, you must first establish your eligibility for coverage.
While many beneficiaries ask “how much does Medicare pay for portable oxygen concentrators”, which is typically 80% of the rental fee, Medicare will pay nothing at all unless you meet strict medical guidelines.
Eligibility hinges entirely on proving a clear clinical need and using the right medical provider.
Criteria for medical necessity
Your doctor must document that you have a severe lung disease, such as COPD, and that alternative treatments like medications have failed.
Medical eligibility requires a lab test proving your blood oxygen saturation is at or below 88% (or a partial pressure of 55 mmHg or less) while at rest, during exercise, or while sleeping.
Your doctor must certify that your condition is expected to improve with oxygen therapy and write a formal prescription for the equipment.
The importance of a Medicare-approved supplier
Even with a valid prescription, Medicare will only pay for your portable oxygen concentrator if you use a Medicare-approved supplier that “accepts assignment.”
This means the supplier agrees to accept the Medicare-approved amount as total payment for the rental. If you use a non-participating supplier, Medicare will reject the claim entirely, leaving you responsible for 100% of the retail purchase or rental costs out of pocket.

4. Can I Buy A Portable Oxygen Concentrator Outright With Medicare?
No, you cannot buy a portable oxygen concentrator outright using Medicare.
If you’re wondering how much does Medicare pay for portable oxygen concentrators, Medicare only covers approved oxygen equipment through a monthly rental arrangement, not a direct purchase.
If you buy a machine online or from a retail store yourself, Medicare will not reimburse any part of the purchase price.
Instead, Medicare contracts with medical suppliers to rent the equipment for a capped period of 36 months. During this rental time, Medicare pays 80% of the monthly fee, and you pay the remaining 20%.
Buying a unit privately means you assume 100% of the financial responsibility, including all future costs for replacement batteries, accessories, and repairs.
5. What to Do If Your Supplier Refuses a Portable Unit?
If your oxygen supplier refuses to provide a portable unit, it may be due to Medicare contract limitations, equipment availability, or how your prescription is written.
Start by contacting your prescribing doctor to confirm your medical need and request updated documentation if necessary.
You can also ask the supplier to explain the denial in writing, then escalate the issue by contacting your Medicare Advantage plan (if applicable) or Medicare directly to file a complaint or request a review.
If the issue cannot be resolved, consider switching to another Medicare-approved supplier that can better accommodate your portable oxygen prescription needs.
6. FAQs
Does Medicare cover the total cost of buying a portable oxygen concentrator?
No, Medicare does not cover the full purchase cost of a portable oxygen concentrator. If you qualify, Medicare Part B typically provides coverage through a 36-month rental program instead of buying the equipment outright. You usually pay 20% coinsurance after meeting your deductible.
Can I get a portable oxygen concentrator from any medical supply store?
No, you must use a Medicare-approved durable medical equipment (DME) supplier for coverage to apply. In some regions, especially Competitive Bidding Areas, you are required to choose a contracted supplier. Using a non-approved provider may result in denied Medicare reimbursement.
Does Medicare pay for extra batteries for travel?
No, Medicare generally does not cover extra or backup batteries for travel or convenience use. Coverage is limited to medically necessary oxygen equipment and standard accessories needed for daily therapy. Additional batteries required for travel or extended use are usually paid out of pocket.
