Understanding Portable Oxygen Concentrators and How They Work

A portable oxygen concentrator is a medical device that pulls air from the room around you and removes nitrogen, leaving oxygen behind. Unlike oxygen tanks that hold a fixed supply of oxygen gas, concentrators create oxygen on demand while you use them. This means they don't run out as long as they have power and a source of air.

Portable oxygen concentrators range in size from small devices that weigh around 2-3 pounds to larger units that weigh up to 10 pounds. The smallest models fit in a backpack or purse, while larger ones sit on a wheeled cart. Most portable concentrators deliver oxygen through nasal cannulas—small tubes that fit under your nose—or through masks that cover your nose and mouth.

These devices operate using one of two main technologies. Pressure swing adsorption (PSA) is the most common method. In PSA systems, air is forced through a sieve material that absorbs nitrogen. When pressure is released, the nitrogen is expelled, leaving concentrated oxygen. Some newer portable concentrators use a different method called vacuum swing adsorption, which works similarly but through a slightly different mechanical process.

Battery life varies significantly between models. Some portable concentrators run for 2-4 hours on a single charge, while others can operate for 8-10 hours depending on the oxygen setting you use. The higher your oxygen setting, the faster the battery drains. Most users need to charge their device overnight or carry extra batteries when traveling.

Portable oxygen concentrators must be prescribed by a doctor. Your healthcare provider tests your blood oxygen level and determines how much oxygen you need, measured in liters per minute (LPM). Most portable concentrators deliver between 1-3 LPM, though some newer models can provide up to 5 LPM. Understanding your prescribed oxygen level helps you choose a device that meets your medical needs.

Practical Takeaway: Before learning about programs that offer portable oxygen concentrators, understand that you'll need a doctor's prescription stating your oxygen requirement in liters per minute. This prescription is a prerequisite for obtaining a device through any program or vendor.

Medicare Coverage for Portable Oxygen Concentrators

Medicare Part B covers portable oxygen concentrators for beneficiaries who meet certain medical requirements. Medicare requires that a patient have a documented medical need for supplemental oxygen, which means their blood oxygen level must fall below a certain threshold (typically 88% or lower). This requirement protects the program from providing oxygen to people who don't medically need it and ensures devices go to those with genuine respiratory conditions.

When Medicare covers a portable oxygen concentrator, it typically pays for the device itself, a backup concentrator, and accessories like batteries and carrying cases. The program covers both rental and purchase options, though the specific coverage details depend on whether you're getting equipment through a durable medical equipment (DME) supplier that contracts with Medicare.

To obtain a portable oxygen concentrator through Medicare, you need several things in place. First, you must have a current prescription from your doctor stating your oxygen requirement. Second, your doctor must order the equipment through a Medicare-approved DME supplier. Third, the DME supplier submits documentation to Medicare for review. Medicare then determines whether it will cover your device based on your medical records and the information provided.

Medicare covers 80 percent of the approved amount after you've met your Part B deductible. You're responsible for the remaining 20 percent, which is called coinsurance. If you have supplemental insurance (often called Medigap), it may cover some or all of your coinsurance costs. Some people with limited income also have other programs that help with these costs.

The rental-versus-purchase question depends on your situation and how long you expect to need oxygen. Generally, if you'll need oxygen for more than a few months, purchase becomes more cost-effective than continuous rental. However, if your medical condition might improve or change, renting gives you flexibility without a large upfront expense.

Practical Takeaway: Contact a Medicare-approved DME supplier with your prescription to learn what portable oxygen concentrators they stock and what your out-of-pocket costs might be. You can find approved suppliers through Medicare's online directory or by calling 1-800-MEDICARE.

Medicaid Programs and Portable Oxygen Coverage

Medicaid covers portable oxygen concentrators in all 50 states, but coverage rules differ significantly from state to state. Unlike Medicare, which is the same federal program everywhere, Medicaid is jointly funded by federal and state governments, giving each state flexibility in how it runs its program. This means what one state covers may differ from another state's coverage.

Most state Medicaid programs cover portable oxygen concentrators when a doctor prescribes them for medical reasons. Many states require prior authorization, which means the DME supplier must submit your prescription and medical records to the state for approval before providing the device. This authorization process protects state budgets by ensuring devices are medically necessary.

Coverage details vary by state. Some states cover both a primary concentrator and a backup device, while others cover only one. Some states restrict coverage to certain brands or models that meet their cost requirements. A few states limit how often they'll replace or upgrade your device, while others replace it when medically needed.

People on Medicaid often pay nothing out-of-pocket for a portable oxygen concentrator, though some states charge small copayments (usually $1-5). States with limited budgets may have longer wait times for device delivery or may require you to use specific suppliers. In rare cases, some state Medicaid programs have waiting lists for durable medical equipment due to budget constraints, though this is uncommon for oxygen devices.

To obtain a portable oxygen concentrator through Medicaid, you need to be enrolled in your state's Medicaid program and have a current prescription from your doctor. Your doctor or a DME supplier contacts your state Medicaid program with your prescription and medical information. The state reviews the request and either approves or denies it based on medical necessity and state coverage rules.

Practical Takeaway: Contact your state Medicaid office or ask your doctor's office to identify which Medicaid-approved DME suppliers operate in your area. Different suppliers may work with different state Medicaid programs, so confirming the supplier accepts your state's Medicaid before scheduling is important.

Veterans Health Administration Programs

The Veterans Health Administration (VHA), which operates the VA healthcare system, provides portable oxygen concentrators to veterans who have service-connected respiratory conditions or other medical conditions causing oxygen deficiency. Unlike Medicare and Medicaid, the VHA provides equipment through its own system rather than contracting with external suppliers.

Veterans receive portable oxygen concentrators through their VA medical center's respiratory or prosthetics department. When a VA doctor determines that a veteran needs supplemental oxygen, they place an order through the VA's equipment system. The equipment is then provided to the veteran, usually with no cost to the veteran beyond their regular VA copayments or healthcare costs.

VA coverage includes not only the primary concentrator but also backup equipment, batteries, charging equipment, and accessories. The VA recognizes that veterans need reliable backup systems, so it typically provides duplicate devices and replacement parts. This approach differs from some civilian programs that provide minimal backup equipment.

Veterans enrolled in VA healthcare don't pay per-use fees or rental charges for oxygen equipment. However, some veterans pay a small annual VA copayment for their healthcare, and this copayment may apply to equipment in some cases. The amount varies based on the veteran's income level, disability rating, and whether they're receiving service-connected disability compensation.

To obtain a portable oxygen concentrator through the VA, you must be enrolled in VA healthcare and have a VA doctor prescribe the device. Your VA primary care doctor or a VA pulmonologist evaluates your medical need and submits the prescription through the VA's internal ordering system. The VA's prosthetics department then coordinates delivery and provides training on device use.

Veterans can also receive oxygen equipment through VA community care programs if they live far from a VA medical center or if the local VA can't provide timely service. In these cases, the VA pays an outside supplier to provide equipment, and the veteran receives similar benefits through that contracted supplier.

Practical Takeaway: If you're a veteran with VA healthcare, call your VA medical center's respiratory clinic or prosthetics department to discuss your oxygen needs. You don't need to find an external supplier; the VA coordinates everything through its internal system.
