If you're exploring the use of oxygen therapy at home, one of the biggest questions often comes down to cost and coverage. With prices for portable oxygen concentrators ranging from $500 to over $3,000, many are wondering: Will Medicare cover this? And if so — how does it actually work? This guide is built to help you understand what Medicare covers, what to expect from the process, which models are most commonly used, and what other low-cost or DIY options exist to help manage oxygen needs safely and legally. Whether you’re researching for yourself or a loved one, we’ll walk through options, equipment, benefits, limits, and expert-recommended resources to help you make an informed choice.
What Are Oxygen Concentrators and Why Are They Prescribed?
Oxygen concentrators are medical devices that deliver concentrated oxygen to people with chronic respiratory conditions such as:
- Chronic Obstructive Pulmonary Disease (COPD)
- Pulmonary fibrosis
- Severe asthma
- Sleep apnea (in rare cases)
- Long COVID-related lung complications
Unlike oxygen tanks, concentrators don’t need refills. Instead, they draw in room air and filter out nitrogen to deliver oxygen-rich air directly through a nasal cannula or mask.
"Oxygen therapy can dramatically improve quality of life and even longevity for people with low blood oxygen levels," says Dr. Linda Barrett, a respiratory care specialist at the American Lung Association.
Will Medicare Cover the Cost of Oxygen Concentrators?
✅ Yes — but with conditions.
Medicare Part B may cover oxygen equipment as durable medical equipment (DME) if the following apply:
- You have a documented medical need (with blood gas levels or pulse oximetry results)
- Your doctor prescribes oxygen therapy for chronic lung disease or hypoxemia
- You use a Medicare-approved DME supplier
- You’re enrolled in Original Medicare or a Medicare Advantage Plan with DME benefits
Medicare typically rents the equipment on a 36-month contract through a supplier. The patient may be responsible for 20% of the Medicare-approved cost unless they have Medigap or Medicaid.
Most Common Medicare-Covered Oxygen Devices (2025 Update)
While portable oxygen concentrators (POCs) are in high demand, not all brands are covered. Medicare often authorizes rental of stationary/home oxygen units, and some POCs only if medically necessary.
Medicare-Approved Oxygen Concentrator Brands:
- CAIRE Companion 5 – Home-use, continuous flow
- Philips Respironics EverFlo – Quiet, energy-efficient unit
- Inogen At Home Stationary Unit – Compact home option
- Drive Medical DeVilbiss 5 Liter – Known for reliability
Note: Portable units like the Inogen One G4 or G5 are often only covered for people with documented mobility limitations. You may need additional paperwork to qualify.

🧠 Mistakes to Avoid When Navigating Medicare Coverage
- Assuming all oxygen devices are covered — Medicare has strict equipment guidelines.
- Choosing a non-enrolled supplier — Coverage only applies with Medicare-approved vendors.
- Skipping the qualifying documentation — You’ll need recent testing and a doctor’s prescription.
- Expecting to own the device — Medicare typically rents, not sells, these units.
- Delaying the claim — Coverage may lapse if not submitted promptly through a provider.
🧪 Are There DIY or Supplementary Options?
While no DIY device can legally replace a medical oxygen concentrator, some options can complement treatment or ease symptoms (always consult your doctor before trying):
- Breathing apps like Breathe+ or Pranayama to strengthen lung function
- Air-purifying indoor plants (like snake plants or peace lilies) to support air quality
- Pulse oximeter apps for Android/iOS to track levels at home (for monitoring only)
- Respiratory training tools like incentive spirometers or flutter devices
