Does Medicare cover nebulizers?
Usually covered
Medicare Part B covers nebulizers as durable medical equipment, and — unusually for a piece of equipment — also covers the prescribed inhalation medications used in them.
- Covered when A doctor prescribes a nebulizer and inhalation medication for a documented respiratory condition such as COPD or asthma.
- Covered when You need refills of a prescribed nebulizer medication — those are covered under Part B (not Part D) when used with covered DME.
- Not when The nebulizer or medication is used without a doctor's prescription documenting medical necessity.

Nebulizers are covered under Part B's DME benefit when a doctor prescribes one for a respiratory condition like COPD or asthma, documenting why the device is medically necessary.
What surprises people is the medication piece: Part B doesn't just cover the machine, it also covers certain inhalation drugs (like bronchodilator solutions) used with a prescribed nebulizer. That's unusual, since Part B normally excludes most self-administered outpatient drugs — those are usually a Part D matter — but nebulizer medications are billed through Part B specifically because they're administered through covered DME.
As with other DME, the equipment and medications need to come with a doctor's prescription and, in practice, from a supplier that bills Medicare correctly for both the device and the drugs together.
What people typically pay
After the annual Part B deductible, you typically pay 20% coinsurance on both the nebulizer and the inhalation medications when your supplier accepts assignment. A Medigap or Medicare Advantage plan can reduce or eliminate that share, so out-of-pocket costs can be low once coverage applies.
Paying entirely on your own, costs vary widely by device model, whether you rent or buy, and the specific inhalation medications prescribed.
Actual amounts vary by supplier, whether the device is rented or purchased, your specific medications, and any supplemental coverage you carry.
How to actually get it covered
Get a doctor's prescription documenting the medical necessity of a nebulizer and the inhalation medication for your respiratory condition.
Get the nebulizer and medications from a Medicare-enrolled DME supplier.
Confirm the supplier "accepts assignment."
Expect the Part B deductible, then 20% coinsurance, on both the equipment and the prescribed medications.
Use the official supplier directory at medicare.gov/medical-equipment-suppliers to find an enrolled supplier.
Common questions
How much of the nebulizer medication cost does Medicare actually cover?
After you meet the Part B deductible, Medicare pays 80% of the Medicare-approved amount and you're responsible for 20% coinsurance (when your supplier accepts assignment). Because the nebulizer medications are billed through Part B rather than Part D, your Part D pharmacy copays don't apply to them. A Medigap plan can pick up much of that 20% share.
Can I rent a nebulizer through Medicare instead of buying one?
Medicare covers different kinds of DME in different ways — for some items you rent, for some you buy, and for some you can choose, with certain items becoming your property after a set number of rental payments. How a specific nebulizer is handled can vary, so confirm the arrangement with your supplier. Either way, after the Part B deductible you generally pay 20% coinsurance on the Medicare-approved amount.
Why are my nebulizer drugs covered by Part B when my inhaler isn't?
Part B covers certain inhalation drugs used with a prescribed nebulizer because they're administered through covered durable medical equipment. A handheld inhaler generally isn't treated as DME, so its medication is typically handled as a self-administered drug under Part D instead. That's why the same bronchodilator can be billed differently depending on how it's delivered.
What happens if my supplier doesn't accept assignment?
If a DME supplier doesn't participate in Medicare or won't accept assignment, you may be charged more than the Medicare-approved amount. For rented DME in particular, if the supplier won't accept assignment for all rental months you may have to pay the full cost upfront, and Medicare will pay you back later for the amount it covers after your claim is processed. To avoid this, ask whether the supplier participates or accepts assignment before you get the equipment. You can find enrolled suppliers through the directory at medicare.gov.
Does Medicare cover nebulizer refills and replacement supplies?
Yes — refills of a prescribed nebulizer medication are covered under Part B when used with covered DME, subject to the Part B deductible and 20% coinsurance. You'll generally need a current prescription and should order through a Medicare-enrolled supplier that accepts assignment.
