If you require supplemental oxygen but want to maintain an active lifestyle, a Portable Oxygen Concentrator (POC) is likely on your radar. Unlike heavy traditional tanks, POCs are lightweight and designed for travel. But the big question remains: Does Medicare cover them?

The short answer is yes, but with strict conditions. Medicare generally covers POCs as rentals, not purchases, and you must meet specific health criteria.

This guide explains how Medicare coverage works, the eligibility requirements for 2025/2026, and the costs you can expect.

Quick Summary: What You Need to Know

• Coverage Type: Medicare rents the device to you; it typically does not purchase it for you to own.
• Cost: You pay 20% of the monthly rental fee (after your Part B deductible).
• Eligibility: You must have a blood oxygen level of 88% or less and a prescription from a doctor you’ve seen recently.
• Mobility Rule: You must demonstrate mobility within your home to qualify for a portable unit.

What Is a Portable Oxygen Concentrator (POC)?

A Portable Oxygen Concentrator (POC) is a battery-powered medical device that filters nitrogen from ambient air to deliver purified, concentrated oxygen.

Unlike old-fashioned oxygen tanks that run out and need refilling, a POC never runs out of oxygen as long as it has battery power or is plugged in. They are designed for mobility, often weighing between 3 to 10 pounds, making them ideal for seniors who want to leave the house, travel by car, or simply move around their home more easily.

Does Medicare Cover Portable Oxygen Concentrators?

Yes, Medicare Part B (Medical Insurance) covers portable oxygen concentrators, but it classifies them as Durable Medical Equipment (DME).

The “Rental vs. Purchase” Rule

This is the most common misconception. Medicare almost never buys the machine for you to own. Instead, Medicare pays a monthly rental fee to a medical supplier.

• The 36-Month Rule: Medicare pays the supplier a rental fee for 36 months.
• After 36 Months: The supplier usually stops billing Medicare, but they must continue to let you use the equipment for up to 5 years total (the device’s “reasonable useful lifetime”). They must also continue to maintain it and provide supplies (such as tubing) during this period.

Eligibility: Do You Qualify?

To get Medicare to pay for your POC, you must meet strict medical evidence requirements. It is not enough to simply feel short of breath; your medical records must prove specific metrics.

The 3 Core Requirements:

1. Severe Lung Disease: You must have a confirmed diagnosis of COPD, pulmonary fibrosis, cystic fibrosis, or bronchiectasis.
2. Recent Doctor Visit: You must have had a face-to-face appointment with your doctor regarding your breathing condition within 30 days prior to the initial certification.
3. Blood Oxygen Levels: Your doctor must perform an arterial blood gas test or a pulse oximetry test that shows:
   • At Rest: An oxygen saturation level of 88% or less (or arterial PO2 of ≤ 55 mmHg).
   • During Exercise: If your resting levels are normal but drop to 88% or less during activity, you may qualify for a portable unit.
   • Note: If your levels are 89%, you may still qualify if you have complications like edema or pulmonary hypertension.

Crucial “Mobility” Note: To qualify specifically for a portable concentrator (rather than just a stationary home machine), your medical record must show that you are mobile within your home and that the portable equipment allows you to move around. If you are bedridden, Medicare will likely only pay for a stationary home concentrator.

Your Costs: What Do You Pay?

If you have Original Medicare, here is the cost breakdown:

• Part B Deductible: You must pay your annual Part B deductible first ($257 in 2025).
• Coinsurance: Once the deductible is met, Medicare pays 80% of the Medicare-approved rental amount. You pay the remaining 20%.
• Supplements (Medigap): If you have a Medigap plan, it typically covers the 20% coinsurance, meaning your out-of-pocket cost for the machine could be $0.

If you have a Medicare Advantage Plan (Part C): Your plan must cover the same equipment as Original Medicare, but your copays and authorized suppliers may differ. You will likely need to use a supplier in the plan’s specific network.

How to Get a POC Through Medicare

1. See Your Doctor: Schedule a visit specifically to discuss your oxygen needs and get the required testing (oximetry/blood gas) documented.
2. Get the Prescription: Your doctor must issue a detailed order specifying the flow rate (liters per minute) and that you require a portable system.
3. Find a Medicare-Approved Supplier: This is critical. You must use a supplier enrolled in Medicare.
   • Tip: If you live in a “Competitive Bidding Area,” Medicare will only pay if you use specific contract suppliers. You can find these on Medicare.gov.
4. Select the Device: The supplier will determine which machine meets your prescription needs. Note: You often cannot pick the exact brand (e.g., Inogen, Philips) unless the supplier specifically stocks it and it meets your medical prescription.

Important Factors to Consider

Before accepting a device from a supplier, check these three factors:

• Battery Life: Does the battery last long enough for your typical outings? Medicare generally covers the device and standard batteries, but extra batteries for long trips are often an out-of-pocket expense.
• Flow Rate: Ensure the machine can deliver the specified liters per minute (LPM). Many small POCs only offer “pulse dose” (puffs of air) and cannot deliver “continuous flow” over 2 or 3 LPM.
• Airline Travel: While POCs are FAA-approved for air travel, Medicare does not cover oxygen-related costs associated with airline travel (e.g., airline fees or extra batteries required for the flight).

Conclusion

Portable oxygen concentrators are a game-changer for maintaining independence for people with respiratory conditions. While Medicare coverage is available, it is structured as a rental agreement rather than a purchase.

By ensuring your medical records show an oxygen saturation of 88% or less and working with a Medicare-approved supplier, you can secure a device that keeps you active without breaking the bank.
