We have answered this question thousands of times. "Does Medicare cover portable oxygen concentrators?" The short answer is: Medicare pays a fixed monthly allowance to your oxygen supplier, and what equipment you receive depends on what your supplier decides to provide, not on what you prefer or what Medicare technically permits. Here is what that means in practice, and what the public record has to say about it.
Fast Facts: Medicare and Portable Oxygen Concentrators
- How Medicare pays: A fixed monthly allowance to the enrolled DME supplier. The same rate applies regardless of whether the supplier provides tanks, a stationary concentrator, or a portable concentrator.
- Supplier's incentive: A portable oxygen concentrator costs a supplier significantly more than the monthly Medicare allowance. Oxygen tanks and cylinders cost a fraction of that. The reimbursement is identical either way.
- What patients typically receive: Oxygen tanks or a basic stationary concentrator. Portable concentrators through Medicare are rare in practice.
- Waitlist reality: Patients who request a portable concentrator from a Medicare supplier frequently encounter waitlists of 12 to 18 months.
- Equipment condition: Medicare-provided portable concentrators are used units, not new. The supplier has no financial incentive to service or upgrade them.
- Public record note: Securities court filings from 2019 stated that "very little of the business came from the Medicare market" for a major portable concentrator manufacturer. That company's stock fell from $282.92 (September 2018) to approximately $6 per share by 2026.
How Medicare Pays for Home Oxygen Equipment
Medicare Part B covers home oxygen under its durable medical equipment (DME) benefit. The program pays enrolled DME suppliers a fixed monthly allowance based on the category of oxygen equipment prescribed. That allowance is set by the Medicare fee schedule.
Here is the part that most patients never hear: the monthly allowance is the same regardless of what specific equipment the supplier furnishes. Whether the supplier provides compressed gas cylinders, liquid oxygen, a basic stationary concentrator, or a portable oxygen concentrator, Medicare's payment to that supplier does not change based on the equipment choice.
The supplier decides what to provide. The patient receives what the supplier decides.
After 36 months of rental payments, the supplier's monthly billing obligation ends. The supplier is then required to continue providing supplies (cannulas, tubing, filters) for the duration of the patient's medical need at no additional cost. The equipment typically remains the supplier's property.
What a Portable Oxygen Concentrator Actually Costs a Supplier
A new portable oxygen concentrator, purchased at wholesale by a DME supplier, costs several thousand dollars depending on the model. For premium units with current technology, the cost is considerably higher.
Oxygen tanks and cylinders cost a fraction of that. A portable oxygen cylinder can be refilled and reused. A basic stationary concentrator runs a few hundred dollars at supplier cost.
When the payment is fixed and the cost of the equipment varies significantly, the economics are not complicated. Suppliers maximize their return by providing the least expensive equipment that satisfies the prescription. That is not a criticism. It is how fixed-reimbursement programs work.
The result is that the vast majority of Medicare oxygen patients receive tanks or basic stationary units, not portable concentrators, regardless of what they would prefer.
What the Public Record Shows
In September 2018, shares of Inogen, Inc. (ticker: INGN), a Santa Barbara-based manufacturer of portable oxygen concentrators, closed at $282.92. It was the company's all-time high. Analysts described the company as being positioned to transform the home oxygen market by replacing tanks and bottles with portable concentrators, including in the Medicare population.
Inogen stock reaches an all-time closing high of $282.92 per share. Market capitalization exceeds $5 billion. The investment thesis centers on portable concentrators replacing traditional oxygen delivery in the Medicare market at scale.
Inogen stock falls more than 24% in a single day following analyst reports raising questions about the company's growth trajectory and the size of its addressable market.
Securities class action complaints are filed on behalf of investors who purchased Inogen shares between November 2017 and February 2019. The complaints allege the company had "overstated the true size of the total addressable market" for portable oxygen concentrators. The same filings note that "very little of the business came from the Medicare market."
The court grants the defendants' motion to dismiss. Plaintiffs are given leave to amend the complaint. The litigation continues.
Inogen shares trade at approximately $6, a decline of roughly 97% from the 2018 all-time high. Stock price data per public market records.
The lawsuits alleged that the Medicare opportunity for portable oxygen concentrators was presented to investors as far larger and more accessible than the underlying economics supported. The court filings stated plainly that very little of the company's actual business came from the Medicare market.
We will leave it at that.
What Patients Actually Experience
In 14 years of talking to patients and families about oxygen equipment, we have heard the same story in countless variations. A patient is diagnosed with COPD or another condition requiring supplemental oxygen. They ask their Medicare DME supplier about portable concentrators. The supplier says they offer them.
The patient is placed on a waitlist.
Reported waitlist times vary, but 12 to 18 months is a range we hear consistently. Some patients wait longer. Some never reach the front of the list at all before their condition changes or they find another path.
When a portable concentrator does arrive through a Medicare supplier, it has been used by other patients before. The supplier receives a fixed monthly reimbursement. Servicing the device, replacing worn sieve beds, updating the firmware, or swapping out a degrading battery all cost the supplier money against that fixed payment. The financial incentives do not point toward maintenance.
What Owning Your Equipment Looks Like
When you purchase a portable oxygen concentrator directly, a few things change immediately. You receive a new device. Not refurbished, not previously assigned to another patient. New, with a full manufacturer warranty, registered in your name.
You choose the device. If your prescription and lifestyle call for a unit that weighs under five pounds with six pulse dose settings and a full-color display, that is what you get. If you need continuous flow capability, you choose accordingly. No one is selecting equipment for you based on their own cost structure.
You own it outright. There is no 36-month rental clock, no ongoing relationship with a supplier, no equipment that reverts to someone else.
Many patients use health savings account (HSA) or flexible spending account (FSA) funds, which allow the purchase to be made with pre-tax dollars. Financing options are also available. The total cost of ownership over time compares differently than it might appear when you account for what the Medicare rental path actually delivers.
Main Clinic Supply has been doing this since 2012 with no obligation to any manufacturer. We carry every major brand. We service Inogen units in-house with factory-trained technicians. We are not trying to sell you any particular device. We are trying to make sure you understand what your options actually are before you make a decision.
Frequently Asked Questions
Does Medicare cover portable oxygen concentrators?
Medicare Part B pays a fixed monthly allowance to enrolled DME suppliers for home oxygen. The supplier decides what equipment to provide. Because a portable oxygen concentrator costs a supplier significantly more than the monthly Medicare allowance, and that allowance is the same regardless of equipment type, suppliers almost universally furnish oxygen tanks or basic stationary concentrators instead.
Why do Medicare patients usually get tanks instead of portable concentrators?
The economics are straightforward. Medicare's monthly oxygen allowance is fixed regardless of what equipment the supplier chooses to provide. A portable oxygen concentrator costs a supplier several thousand dollars. Oxygen tanks and cylinders cost a fraction of that. When the reimbursement is the same either way, suppliers have every financial incentive to furnish the less expensive option.
Can I request a portable oxygen concentrator through Medicare?
You can request one, and some suppliers will tell you they offer portable concentrators through Medicare. Many patients who make that request are placed on a waitlist. Reported wait times commonly run 12 to 18 months. The equipment, when it does arrive, is used, not new.
What happens to a portable oxygen concentrator provided through a Medicare supplier?
The supplier receives a fixed monthly reimbursement. Maintaining, servicing, or upgrading the equipment costs the supplier money against that fixed payment. Patients who receive Medicare-provided portable concentrators typically receive used units that have passed through multiple patients before them.
What does the public record say about portable oxygen concentrators and Medicare?
Securities class action complaints filed in 2019 alleged that a publicly traded portable oxygen concentrator manufacturer had overstated the total addressable market for its devices. Those court filings noted explicitly that "very little of the business came from the Medicare market." The case involved Inogen, Inc. (INGN), whose stock fell from an all-time high of $282.92 in September 2018 to approximately $6 per share by 2026.
What is the alternative to waiting for a Medicare-provided portable concentrator?
A direct retail purchase gives you a new device with a manufacturer warranty, of your choosing, without a waitlist. Many patients use HSA or FSA funds, financing options, or a combination. Main Clinic Supply can walk you through every option and help you compare devices based on your prescription and lifestyle.
Is buying a portable oxygen concentrator worth it if I have Medicare?
That depends on your situation and your priorities. Patients who buy directly own a new device, choose the model that fits their life, and carry a full manufacturer warranty. Patients who wait for a Medicare-provided unit receive used equipment after a lengthy wait, with no ability to specify the model. Both paths are valid, but the differences are worth understanding before you decide.
How long has Main Clinic Supply been helping patients understand oxygen equipment options?
Main Clinic Supply has specialized exclusively in portable oxygen concentrators since 2012, serving patients and families across the United States and Canada. We have helped more than 10,000 patients navigate these decisions with no obligation to any single manufacturer.
