What Medical Equipment You May Need for COPD

COPD often requires medical equipment to help you breathe more easily and monitor your lung function at home. The most common pieces are oxygen concentrators or portable oxygen tanks, nebulizers to deliver inhaled medication, and pulse oximeters to track your oxygen levels. Your doctor will prescribe specific equipment based on how advanced your COPD is, how much oxygen your blood needs, and what your daily routine looks like.

Not all equipment is the same. A stationary oxygen concentrator plugs into the wall and pulls oxygen from the air around it — useful if you spend most time at home. Portable oxygen tanks let you move around but need refilling. Nebulizers turn liquid medication into a mist you breathe in, which works better for some people than inhalers. Your doctor's prescription will specify which type and how often you need to use it.

Insurance coverage depends on whether your doctor documents medical necessity. Medicare covers oxygen equipment if your blood oxygen level is below a certain threshold, measured by a blood gas test or pulse oximetry. Private insurance and Medicaid rules vary by state and plan. The equipment itself can cost hundreds to thousands of dollars without insurance, so understanding your coverage before you buy or rent is critical.

Key Takeaways

  • Your doctor must prescribe medical equipment and document why you need it; you cannot buy it on your own and expect insurance to cover it later.
  • Medicare covers oxygen equipment if your blood oxygen level meets their threshold, confirmed by a test ordered by your doctor.
  • Oxygen can be rented or purchased, and rental is often cheaper upfront but costs more over time if you need it long-term.
  • Durable medical equipment (DME) suppliers deliver, set up, and maintain your equipment, and they bill your insurance directly.
  • You will need to renew prescriptions and equipment orders periodically, usually every 12 months, or your coverage may stop.

How to Get a Prescription for Medical Equipment

Start by talking to your pulmonologist or primary care doctor about what equipment would help you. They will order tests — usually a blood gas test or pulse oximetry reading — to measure your oxygen level and document the medical need. This test result is what insurance companies use to decide whether to cover the cost. Without it, you will be paying out of pocket.

Once your doctor has the test results, they write a prescription that specifies the type of equipment, how often you use it, and how much oxygen you need (measured in liters per minute). This prescription goes to a durable medical equipment (DME) supplier — a company licensed to rent or sell medical equipment. Your doctor's office can recommend one, or you can search for DME suppliers in your area that accept your insurance.

The DME supplier will contact your insurance to verify coverage before they deliver anything. This step prevents surprises. If your insurance denies coverage, the supplier can tell you the reason and sometimes help your doctor appeal the decision. If you do not have insurance or your plan does not cover it, ask the supplier about rental versus purchase options and payment plans.

Medicare Coverage for Oxygen and Equipment

Medicare Part B covers oxygen equipment and supplies if your doctor orders them and your blood oxygen level is 55 millimeters of mercury or lower, or between 56 and 60 if you also have heart problems or a high red blood cell count. The test must be done by a Medicare-approved provider, usually your doctor's office or a hospital lab. A single test result is enough to start coverage, but Medicare may ask for a follow-up test after a few months to confirm you still need it.

Medicare pays the DME supplier directly, and you pay your share of the cost — usually 20 percent of the approved amount after you meet your Part B deductible. If you rent equipment, Medicare covers the rental for up to 36 months, after which the equipment becomes yours. If you buy equipment outright, Medicare covers 80 percent of the approved purchase price.

Your prescription and coverage must be renewed every 12 months. If your doctor does not reorder it, your DME supplier will stop delivering supplies and your coverage ends. Set a reminder to contact your doctor's office three months before your prescription expires so there is time to renew it without a gap in your equipment or supplies.

Private Insurance and Medicaid Coverage

Private insurance plans vary widely in what they cover and what you pay out of pocket. Some plans cover oxygen equipment with a copay; others require you to meet a deductible first. Some plans only cover rental, not purchase. The best way to find out is to call the customer service number on your insurance card and ask specifically: "Does my plan cover oxygen equipment? What is my copay or coinsurance? Do I need prior authorization from my doctor?"

Medicaid coverage also differs by state. Some states cover oxygen equipment generously; others have stricter rules or longer wait times. Contact your state Medicaid office or your Medicaid managed care plan to ask what equipment is covered and what paperwork your doctor needs to submit. If your state Medicaid does not cover something your doctor prescribed, ask whether there is an appeal process or whether a different piece of equipment might be covered instead.

If your insurance denies coverage, ask the DME supplier or your doctor's office to request a peer-to-peer review — a conversation between your doctor and the insurance company's medical director. Sometimes this conversation changes the insurance company's decision. If it does not, you have the right to file a formal appeal, usually within 60 days of the denial letter.

Renting Versus Buying Equipment

Renting oxygen equipment costs less upfront — usually $50 to $150 per month — but the total cost adds up if you need it for years. Buying equipment costs more initially, often $1,500 to $3,000, but you own it and do not pay monthly rental fees. If your insurance covers rental, the math often favors renting for the first few years. If you need equipment long-term, buying eventually becomes cheaper.

Medicare's rental-to-own program lets you rent for 36 months, and then the equipment is yours. You pay the same rental amount each month, and after 36 months, you stop paying and keep the equipment. This is often the best deal if Medicare covers your oxygen, because you get a known cost and eventually own the equipment.

If you buy equipment, you are responsible for maintenance and repairs after the warranty ends. If you rent, the DME supplier handles repairs and replacements. This matters if equipment breaks — a rented concentrator gets swapped out quickly, but a purchased one may need to be sent in for service. Ask the DME supplier what their repair turnaround time is before you decide to buy.

Finding and Working With a DME Supplier

A DME supplier is a company that delivers, sets up, and maintains your medical equipment. They are licensed by your state and must accept Medicare or your insurance plan. Your doctor can recommend one, or you can search online for "DME suppliers near me" and call a few to compare. Ask whether they deliver to your home, whether they offer 24-hour support if equipment breaks, and how long it takes them to deliver after your prescription arrives.

When you call a DME supplier, have your insurance information and your doctor's name ready. They will verify your insurance coverage, explain what you will pay, and schedule a delivery time. Most suppliers deliver within a few days to a week. They will show you how to use the equipment, how to clean it, and when to replace filters or supplies. Ask them to write down the instructions or provide a manual you can keep.

If you are unhappy with your DME supplier — they are slow to deliver, do not answer calls, or charge you for things insurance should cover — you can switch to a different supplier. Your doctor's prescription stays valid, and you can take it to another company. Do not stay with a supplier that is not serving you well.

Portable Oxygen and Traveling With Equipment

If you need oxygen and want to leave home, you have options. Portable oxygen concentrators are battery-powered devices that weigh 2 to 10 pounds and produce oxygen on demand. They cost more than stationary concentrators but let you move around your home and travel. Portable oxygen tanks are lighter and cheaper but need refilling and run out of oxygen after a few hours of use.

If you travel by airplane, you must notify the airline in advance — most do not allow you to bring your own oxygen concentrator on board, but they can arrange oxygen service at your destination. Contact the airline at least 48 hours before your flight. If you drive, you can bring portable oxygen tanks, but they must be secured and transported safely. Ask your DME supplier for information on traveling with your specific equipment.

Some people use a combination: a stationary concentrator at home and a portable tank or concentrator for outings. Your doctor can prescribe both if you need them. Insurance may cover both, or you may need to pay for the portable option yourself. Ask your DME supplier what the total cost would be before you commit.

Frequently Asked Questions

What if my doctor says I need oxygen but my blood oxygen test is not low enough for insurance to cover it?

Ask your doctor to order the test again or to order it under different conditions — for example, during exercise or at night, when oxygen levels often drop. Some people have normal oxygen levels at rest but low levels during activity. If a second test still does not meet the threshold, ask your doctor whether a trial period of oxygen might help you feel better, and whether insurance will cover it on a trial basis. If not, you can purchase oxygen equipment yourself, though it will be expensive.

Can I use someone else's oxygen equipment or buy used equipment to save money?

Used equipment can work, but there are risks. Oxygen concentrators need regular maintenance and cleaning, and you cannot see inside to know whether the previous owner maintained it properly. If it breaks, repairs may cost more than a new one. Renting is usually safer and not much more expensive. If you are struggling to afford equipment, ask your doctor or DME supplier about patient information programs or nonprofit organizations that help with medical equipment costs.

What happens if I stop needing oxygen — do I have to keep paying for it?

No. Contact your DME supplier and tell them you want to stop the rental or return the equipment. If you are renting, they will pick it up and stop billing you. If you bought it, you own it and can keep it or donate it. Your doctor can also write a note saying you no longer need oxygen, which stops insurance coverage. If you think you might need it again later, you can ask your doctor to order another test before you return the equipment.

How often do I need to replace oxygen supplies like tubing and masks?

Tubing, nasal cannulas, and masks should be replaced every few months or when they crack, become stiff, or stop fitting well. Your DME supplier will send you replacement supplies regularly — usually every 30 to 90 days — as part of your rental or coverage. If you are not receiving supplies, contact them. Medicare and most insurance plans cover these supplies as part of your equipment coverage, so you should not be charged extra for them.

What if my insurance stops covering my equipment?

Contact your insurance company and ask why coverage ended. Common reasons are that your prescription expired and your doctor did not renew it, or your plan changed. If your prescription expired, contact your doctor's office when ready and ask them to reorder it. If your plan changed, ask your insurance company whether the new plan covers oxygen equipment and what the process is. If coverage is truly denied, ask about the appeal process or contact your state's insurance commissioner's office for help.
