If you’re shopping for a portable oxygen concentrator or portable oxygen machine, one of the first questions you probably have is: Will Medicare pay for it? Oxygen equipment can be expensive, and understanding how Medicare coverage works can save you thousands of dollars and a lot of frustration. In this guide, we’ll break it down in plain English so you know what to expect.
How Medicare Covers Oxygen Equipment
In the United States, oxygen equipment is generally covered under Medicare Part B, which falls under Durable Medical Equipment (DME). According to the Centers for Medicare & Medicaid Services (CMS), Medicare covers medically necessary oxygen equipment when prescribed by a doctor and when certain qualification requirements are met.
However — and this is important — Medicare usually does not simply “buy” a portable oxygen concentrator for you.
Instead:
-
Medicare typically rents oxygen equipment.
-
The supplier receives monthly rental payments.
-
After 36 months of rental payments, ownership arrangements change, but maintenance coverage may continue for up to five years.
In most cases, Medicare pays 80% of the approved amount, and the patient is responsible for the remaining 20% (unless they have supplemental insurance).
Does Medicare Pay for a Portable Oxygen Concentrator Specifically?
Here’s where things get a little tricky.
Medicare covers oxygen equipment, but it does not guarantee coverage for a specific brand or model, especially when it comes to a high-end portable oxygen concentrator.
Many patients assume that if they want a lightweight, travel-friendly portable oxygen machine, Medicare will automatically pay for it. That’s usually not how it works.
Medicare-approved suppliers often provide:
-
Stationary home oxygen concentrators
-
Larger, less expensive portable units
-
Oxygen tanks
If you prefer a premium, lightweight device — such as models from Inogen, Philips, or Caire — you may need to pay out-of-pocket if your supplier does not offer that specific model under their contract.
What About Inogen and Other Major Brands?
Let’s look at some well-known names in the market:
-
Inogen is one of the most recognized portable oxygen concentrator brands in the U.S., especially known for lightweight travel units.
-
Philips (including models previously sold under Philips Respironics) has offered home and portable oxygen solutions.
-
Caire is another established manufacturer with both stationary and portable options.
-
HIDGEEM focuses on portable oxygen machines designed for flexibility and ease of mobility.
Some of these companies advertise Medicare support — but here’s what that usually means:
They may help you determine eligibility, or they may work with Medicare-approved suppliers. However, coverage depends on the supplier contract and medical qualification, not simply on the brand name.
For example, Inogen has historically focused heavily on private-pay customers, meaning many buyers purchase their device directly rather than going through Medicare rental programs.
So yes — Medicare may cover oxygen equipment. But it may not cover the exact portable oxygen concentrator you want.
Why Doesn’t Medicare Cover All Portable Models?
Cost is one factor.
Portable oxygen concentrators can range from approximately $2,000 to $4,000+ depending on features, weight, and battery life. Medicare’s reimbursement rates are based on standardized pricing, not retail pricing for premium devices.
Suppliers are paid a fixed monthly rental rate, so they typically provide equipment that fits within those reimbursement limits.
That’s why many patients who want:
-
Ultra-lightweight devices
-
Long battery life
-
Travel-friendly designs
often decide to purchase their portable oxygen machine separately instead of relying on Medicare rental options.
When Might It Make Sense to Buy Instead?
Many Americans choose to purchase their own portable oxygen concentrator when:
-
They travel frequently.
-
They want a backup unit.
-
They prefer a specific brand like Inogen, Philips, Caire, or HIDGEEM.
-
They don’t want to deal with long-term rental contracts.
Buying outright gives you more flexibility and control over the exact model you use.
Key Takeaways
-
Medicare Part B covers oxygen equipment under DME.
-
Medicare usually rents equipment instead of purchasing it.
-
Coverage depends on medical qualification and supplier contracts.
-
Premium portable oxygen concentrators may not be fully covered.
-
Brands like Inogen, Philips, Caire, and HIDGEEM may or may not be available through Medicare-approved suppliers.
Before making a decision, always:
-
Confirm your eligibility with your doctor.
-
Contact a Medicare-approved supplier.
-
Compare rental vs. purchase costs carefully.
Understanding how Medicare works can help you choose the right portable oxygen concentrator with confidence — and avoid unexpected expenses along the way.
