If you’re one of the nearly 1.5 million U.S. adults who use supplemental oxygen every year in an outpatient setting,1 then portable oxygen concentrators (POCs) — like the lightweight Inogen Rove 4 — may be able to help you stay active, travel, and maintain independence.
If you’re on Medicare and have been prescribed supplemental oxygen, Medicare Part B may help cover some of the costs. However, it will typically help you cover 80 percent of a rented unit, not purchase a new unit of your choice.
In this guide, we’ll dive into:
- What Medicare will and won’t cover when it comes to POC rentals
- Eligibility under Medicare’s requirements
- Additional coverage options like Medicare Advantage, Medigap, and Medicaid
- What to do if you want a specific POC model
Before Getting Started: Ask your doctor to document your oxygen needs, including: your prescribed flow rate in liters per minute, whether you need oxygen around the clock or only during activity or sleep, and whether your mobility outside the home requires a portable unit.
Does Medicare Cover a Portable Oxygen Concentrator?
While Medicare Part B considers oxygen equipment as durable medical equipment (DME), it will not cover the purchase of a unit. Instead, it will pay a monthly rental fee using a 36-month capped rental structure to a Medicare-approved DME supplier who provides the equipment, accessories, and maintenance.
Air Travel Coverage: Medicare doesn’t cover oxygen equipment for air travel. If you need a portable oxygen concentrator specifically for a flight, that cost is fully out of pocket. Short-term travel rentals are available from specialized companies, but Medicare will not reimburse them2
Medicare’s 36-Month Rental Structure
During the first 36 months, Medicare pays the approved monthly rental fee and you pay your 20 percent coinsurance. This covers the equipment, accessories, maintenance and repairs.
After 36 months, rental payments for the equipment stop — but your supplier must still provide the equipment and supplies for an additional 24 months, for a total of five years.
This structure means you never own the equipment through Medicare. If your medical need continues after five years, and you still need oxygen and equipment, you must get new equipment and Medicare will start a new 36-month of payment. If you stop needing oxygen therapy or lose coverage at any point during the five-year window, the equipment is returned to the supplier.2
Note: During the post-36-month period, your supplier may still charge a coinsurance payment every six months for in-home maintenance visits if they actually come to your home to inspect and service the equipment. This is separate from the rental fee and only applies when a physical service visit occurs.
Medicare Part B Deductible
In 2026, the Medicare Part B deductible is $283 for the year. After meeting that deductible, Medicare generally covers about 80 percent of the approved oxygen equipment rental cost, leaving you responsible for the remaining 20 percent coinsurance. For many patients, that translates to an estimated monthly out-of-pocket cost of roughly $30–$80, though the exact amount varies based on local approved rental rates.
Tip: Many people who want a lightweight, travel-friendly portable oxygen concentrator choose to pay for the device themselves while using Medicare coverage for a separate home oxygen setup.
Medicare’s Requirements for a POC Rental
Medicare sets specific clinical thresholds to determine whether you qualify for covered oxygen therapy. These are documented requirements established in CMS coverage guidelines, and your doctor must confirm and record them before a supplier can bill Medicare on your behalf.
Primary Qualifying Criteria: Blood Oxygen Levels
You will generally qualify if diagnostic testing shows one of the following while you are at rest, awake, and breathing room air:
- Arterial blood gas (PaO2) at or below 55 mmHg
- Oxygen saturation (SaO2) at or below 88 percent
You may also qualify:
- If your testing shows levels of PaO2 between 56 and 59 mmHg or SaO2 of 89 percent
- And if you have documented evidence of related organ complications (e.g., pulmonary hypertension, cor pulmonale, or congestive heart failure)
In borderline cases, Medicare requires additional medical review. If this applies to you, be sure you have thorough documentation from your doctor.
Important Note
Medicare generally doesn’t accept qualifying tests conducted solely during sleep or during an acute illness flare-up. Your blood oxygen levels must be tested while you are in a stable clinical state, at rest, and breathing room air — not while supplemental oxygen is already in use.
Full Qualifying Criteria
Use this checklist to help determine if you’re eligible for POC coverage through Medicare.
| Requirement | What Medicare Needs | Why It Matters |
|---|---|---|
| Enrollment | Active Medicare Part B plan | DME coverage is a Part B benefit |
| Diagnosis | Severe lung disease or documented hypoxemia | Must reflect an ongoing medical need |
| Blood oxygen levels at rest | PaO2 ≤ 55 mmHg or SaO2 ≤ 88 percent |
Core clinical threshold for coverage |
| Prescription | Doctor's specified flow rate and frequency of use | Required before supplier can file claim |
| Medicare-approved supplier | Must use a contracted DME supplier | Non-contracted suppliers cannot bill Medicare |
| Mobility documentation | Proof of need for portable unit beyond home use | Required to qualify for POC vs. home unit only |

Additional Coverage Options
Seniors who supplement their coverage with Medicare Advantage (Part C) or Medigap may be eligible for coverage of their 20 percent coinsurance, depending on their plan. See more details below.
Medicare Advantage
If you have a Medicare Advantage (Part C) plan, your plan is required to cover at least everything Original Medicare covers, including oxygen therapy. However, cost-sharing structures, supplier networks, and prior authorization requirements can differ substantially from plan to plan.
Some Advantage plans offer additional DME benefits not available through Original Medicare, while others may have more restrictive supplier networks.
Medigap
A Medigap supplemental policy can cover your 20 percent Part B coinsurance on DME rentals, depending on which Medigap plan you have. For those who need years-long oxygen therapy, eliminating the 20 percent monthly coinsurance through Medigap can represent meaningful cumulative savings.
If you’re approaching the age of 65 and anticipate needing oxygen therapy, we recommend speaking with a licensed Medicare insurance counselor before your initial enrollment window closes.
Medicaid
Medicaid may also help cover oxygen therapy costs for eligible low-income seniors and disabled adults. Coverage rules vary by state, but Medicaid often assists with Medicare cost-sharing expenses such as deductibles, copayments, and coinsurance for durable medical equipment, including oxygen equipment rentals.
For people who qualify for both Medicare and Medicaid (“dual eligible” beneficiaries), Medicaid may cover some or all of the remaining out-of-pocket costs after Medicare pays its share. Because Medicaid programs are administered at the state level, supplier participation rules, prior authorization requirements, and covered equipment options can differ significantly depending on where you live.
What to Do if You Want a Specific POC Model
If you want a specific portable oxygen concentrator rental that isn’t covered by Medicare:
- Try contacting the manufacturer directly. The manufacturer’s insurance team could verify your Medicare eligibility and may coordinate with your physician to submit required documentation. They can tell you upfront whether a covered rental is feasible for your plan.
- Ask your doctor to document portability. If your doctor explicitly documents that your medical condition requires a portable concentrator (not just a stationary home unit), this strengthens your case for a POC rather than a tank system.
- Shop for a Medicare-participating supplier. Different suppliers have different POC offerings. If your current supplier only provides tanks, it's worth contacting other Medicare-approved suppliers in your area to see whether any offer lightweight POC rentals.
- Consider purchasing out of pocket. If your supplier cannot provide the specific model you need through Medicare, purchasing a new or certified pre-owned unit out of pocket may be the most direct path to the device you want. HSA and FSA funds can be used for the purchase.
Tip: When calling a DME supplier's insurance team, ask specifically whether they “accept Medicare assignment” for POCs. A supplier that accepts assignment agrees to charge you only the Medicare-approved coinsurance amount and cannot bill you beyond that. A non-participating supplier can charge more — so this question matters to your wallet.
Our Methodology
Our goal for evaluating Medicare coverage for portable oxygen concentrators is to help you understand what Medicare does and does not pay for, how the rental structure works, and potential out-of-pocket costs.
The Senior List editorial team reviewed current Medicare Part B oxygen equipment policies, CMS guidance, durable medical equipment (DME) supplier requirements, and publicly available pricing information related to portable oxygen concentrator rentals and ownership costs. We also reviewed eligibility standards for oxygen therapy coverage, including blood oxygen qualification thresholds, prescription requirements, and supplier participation rules.
To provide practical guidance for readers comparing their options, we evaluated how Medicare coverage interacts with:
- Portable oxygen concentrator rentals
- Medicare Advantage plans
- Medigap supplemental coverage
- HSA and FSA eligibility
- Out-of-pocket purchase options for patients seeking a specific POC model
Our editorial team also consulted peer-reviewed medical literature related to oxygen therapy and interviewed a healthcare expert to ensure our coverage reflects both clinical considerations and real-world patient experiences.
Bottom Line
Medicare Part B can help partially cover portable oxygen concentrators for qualifying beneficiaries, but keep in mind that with this coverage:
- You don’t own the equipment
- Your supplier may provide tanks rather than a modern lightweight POC
- You may not get your preferred unit through Medicare’s coverage
