Medicare Part B covers nebulizers as durable medical equipment, but only when a doctor prescribes one for a medical reason and you meet specific requirements

Medicare will pay for a nebulizer if your doctor writes an order saying you need one to treat a chronic lung condition like asthma, COPD, or cystic fibrosis. The machine itself is covered under Part B durable medical equipment benefits. You pay 20 percent of the approved amount after you have met your Part B deductible for the year. Medicare pays the remaining 80 percent directly to the supplier.

The coverage applies to the nebulizer machine and the tubing and mask that come with it. Replacement parts like tubing, masks, and medication cups are also covered when medically necessary. However, the medications you put in the nebulizer — such as albuterol or other breathing treatments — are covered separately under Part D prescription drug coverage, not as part of the equipment benefit.

Your doctor must document that the nebulizer is medically necessary for your condition. Medicare will not cover a nebulizer straightforward because you prefer it to an inhaler, even if both can deliver the same medication. The prescription must show that you have a condition that makes a nebulizer the appropriate treatment choice.

Key Takeaways

  • Your doctor must write a prescription stating that a nebulizer is medically necessary for your specific lung condition.
  • You pay 20 percent of the Medicare-approved cost after meeting your Part B deductible; Medicare covers the other 80 percent.
  • The nebulizer machine, tubing, and mask are covered, but the medications you use in it are covered under Part D prescription benefits.
  • You must use a Medicare-approved supplier to rent or purchase the equipment for Medicare to pay its share.
  • If your condition changes or your doctor says you no longer need the nebulizer, Medicare coverage will end.

How to get Medicare to pay for your nebulizer

Start by talking to your doctor about whether a nebulizer would help your breathing. If your doctor agrees it is medically necessary, ask them to write a prescription or order for durable medical equipment. The order should state your diagnosis and explain why a nebulizer is the right tool for your treatment.

Once you have the prescription, contact a Medicare-approved durable medical equipment supplier in your area. You can find approved suppliers by visiting Medicare.gov and using their supplier search tool, or by calling 1-800-MEDICARE. Give the supplier your Medicare number and the doctor's prescription. The supplier will handle the paperwork with Medicare and bill your insurance directly.

Before the supplier sends the equipment, Medicare will review the prescription to make sure it meets coverage rules. This review usually takes a few days. If Medicare approves it, the supplier will deliver the nebulizer to your home. You will receive a bill for your 20 percent share after your deductible is met.

What happens if Medicare denies coverage

Medicare may deny coverage if your doctor's prescription does not clearly state that the nebulizer is medically necessary, or if the diagnosis on the order does not match Medicare's coverage rules for nebulizers. Common reasons for denial include a prescription that says "patient preference" instead of medical need, or a condition that Medicare does not consider appropriate for nebulizer treatment.

If your claim is denied, you have the right to appeal. The supplier should send you a notice explaining why Medicare said no. You can ask your doctor to provide more detailed medical information, and the supplier can resubmit the claim with that documentation. Many denials are overturned on appeal when the doctor clarifies the medical reason.

If the appeal is also denied, you can request a formal review by an independent reviewer who is not part of Medicare. The supplier can tell you how to start this process, or you can call 1-800-MEDICARE for help.

Renting versus buying a nebulizer through Medicare

Medicare covers both renting and purchasing a nebulizer, and the supplier you work with will usually recommend one option based on your situation. For short-term use — such as treatment for a temporary condition — renting is often the better choice because you pay a smaller amount each month and do not own equipment you may not need later.

For long-term or permanent use, purchasing usually becomes the better financial choice. Once you have rented a nebulizer for a certain number of months, the total rental cost reaches the purchase price, and Medicare will then cover the purchase instead. The exact rental period varies by equipment type, but Medicare has set limits on how long you can rent before you must buy.

The supplier will explain both options and help you understand which makes sense for your situation. Either way, you pay the same 20 percent coinsurance after your deductible, and Medicare covers 80 percent.

Medications for your nebulizer are covered under Part D, not Part B

The nebulizer machine itself is covered under Part B, but the liquid medications you use in it — such as albuterol, ipratropium, or budesonide — are covered under your Part D prescription drug plan. This means you may have a different copay or coinsurance for the medication than you do for the equipment.

Some nebulizer medications are on the generic tier of most Part D plans, which usually costs less. Others may be brand-name drugs with higher copays. Check your Part D plan's formulary (the list of covered drugs) to see what your cost will be for the specific medications your doctor prescribes. If the copay is too high, ask your doctor whether a generic version or a different medication might work for you.

If you do not have Part D coverage, you can still use your nebulizer, but you will pay the full cost of the medications out of pocket. You may want to talk to your doctor about whether a less expensive inhaler might be an option, or whether you should enroll in Part D during the next enrollment period.

When Medicare stops paying for your nebulizer

Medicare coverage ends if your doctor determines that you no longer need the nebulizer for medical reasons. This might happen if your condition improves, if you switch to a different treatment, or if your doctor finds that an inhaler works just as well for you. Your doctor should notify the supplier in writing when coverage should end.

If you are renting the nebulizer, you straightforward stop paying the rental fee once the supplier receives the notice from your doctor. If you purchased it, the equipment is yours to keep, but Medicare will not pay for repairs or replacements after coverage ends.

If you move to a different state or change your Medicare coverage, let your supplier know right away. Coverage rules can vary slightly by location, and your new plan may have different equipment benefits.

What to ask your doctor about nebulizer coverage

Before your appointment, write down these questions so you do not forget to ask them:

  • Do you think a nebulizer would help my breathing condition?
  • Will you write a prescription for durable medical equipment so Medicare can cover it?
  • Should I rent or buy the nebulizer?
  • What medications will I use in the nebulizer, and are they covered under my Part D plan?
  • How often should I use the nebulizer, and for how long?
  • What should I do if the nebulizer stops working or needs repair?
  • Will you let me know if I no longer need the nebulizer, or should I check back with you?

Frequently Asked Questions

Does Medicare Advantage cover nebulizers the same way as Original Medicare?

Medicare Advantage plans must cover at least what Original Medicare covers, but some plans may have different rules about which suppliers you can use or how much you pay. Call your Advantage plan before ordering a nebulizer to find out whether there are any extra requirements or different costs. Some plans require prior approval from the plan before the supplier orders the equipment.

What if I already own a nebulizer and want Medicare to pay for a new one?

Medicare will cover a replacement nebulizer if your doctor says the old one no longer works and you need a new one for medical reasons. The supplier will need a new prescription from your doctor stating that replacement is medically necessary. You will pay the same 20 percent coinsurance as you would for a first-time purchase.

Can I use any nebulizer I buy online, or does it have to come from a Medicare supplier?

You can buy any nebulizer you want, but Medicare will only pay for one that comes from a Medicare-approved supplier. If you buy one on your own from an online retailer or pharmacy, Medicare will not reimburse you. Always order through an approved supplier if you want Medicare to cover the cost.

Will Medicare pay for a portable or travel nebulizer?

Yes, Medicare covers portable and travel nebulizers if your doctor prescribes one and it is medically necessary. Portable models may cost more than standard home nebulizers, but Medicare applies the same 20 percent coinsurance rule. Ask your supplier whether a portable model is available and what the approved cost is.

What if my doctor says I need a nebulizer but Medicare denies it?

Ask your doctor to provide more detailed medical documentation explaining why the nebulizer is necessary for your specific condition. Have the supplier resubmit the claim with this additional information. If Medicare denies it again, you can request an independent review. Your doctor and the supplier can help you through the appeal process.
