Quick Answer
Yes, Medicare covers asthma inhalers through Medicare Part D prescription drug plans. Your doctor must provide a prescription, and coverage depends on your plan's formulary (drug list). Most Part D plans cover common inhalers like Albuterol and Flovent, though coverage and tier placement vary by plan. Medicare Part B covers nebulizers as durable medical equipment, and Part B also covers outpatient pulmonary rehabilitation for chronic conditions like asthma.
Coverage Comparison by Plan Type
| Plan Type | Coverage | Notes |
|---|---|---|
| Medicare Part D (Prescription Drugs) | Covered | Covers prescription inhalers based on plan formulary; costs vary by drug tier |
| Medicare Part B (Outpatient) | Partial | Covers nebulizers as DME and outpatient pulmonary rehab; does not cover inhalers |
| Medicare Part A (Inpatient) | Covered | Covers inhalers and breathing treatments administered during a hospital stay |
| Medicare Advantage (Part C) | Covered | Most MA plans include Part D drug coverage; inhaler coverage follows plan formulary |
Understanding Your Coverage Options
Medicare Part D (Prescription Drug Plans)
Covers prescription inhalersMedicare Part D is the primary source of coverage for prescription asthma inhalers. If your doctor prescribes an inhaler for asthma treatment, your Part D plan will cover it based on the plan's formulary (list of covered drugs). Each Part D plan has its own formulary, so coverage and costs can vary significantly between plans.
Inhalers are placed on different drug tiers within your plan's formulary, with lower-tier drugs generally costing less. Generic inhalers like Albuterol are typically on lower tiers (Tier 2), while brand-name inhalers may be on higher tiers with greater cost-sharing. Talking to your doctor about generic alternatives can save you money.
It is important to have a stand-alone Part D plan even if you do not currently take medications. Without Part D coverage, you may face a late enrollment penalty that permanently increases your premiums when you do eventually enroll.
What It Covers
- Prescription rescue inhalers (e.g., Albuterol, Ventolin)
- Maintenance inhalers (e.g., Flovent, Symbicort, Advair)
- Combination inhalers for asthma and COPD
- Generic and brand-name inhaler options based on formulary
- Bronchodilators that assist in opening airways
What It Doesn't Cover
- Inhalers not listed on your plan's formulary
- Over-the-counter inhalers (no prescription required)
- Nebulizers (covered under Part B as DME, not Part D)
Inhaler costs under Part D depend on the drug tier: Tier 1-2 generics may cost $0–$15 per fill, while Tier 3-4 brand-name inhalers may cost $30–$100+ per fill. Costs vary by plan.
Check Your Plan's Formulary
Before enrolling in a Part D plan, review the formulary to confirm your specific inhaler is covered and check which tier it falls on. You can also ask your pharmacist about pricing outside your insurance, as the elimination of the gag clause allows pharmacists to share this information.
Medicare Part B (Outpatient & DME)
Covers nebulizers and pulmonary rehabWhile Medicare Part B does not cover prescription inhalers (that falls under Part D), it does cover related respiratory equipment and treatment. Part B covers nebulizer machines as durable medical equipment (DME) when prescribed by your doctor. Nebulizers deliver medication as a mist that you breathe in, and they are an alternative to inhalers for some patients.
Part B also covers outpatient pulmonary rehabilitation for chronic respiratory conditions, including asthma. Pulmonary rehab programs typically last 6 to 8 weeks and include exercise training, education, health management, mental health counseling, and group support. When recent tests show poor lung function, Part B covers therapy to restore lung function and improve quality of life.
What It Covers
- Nebulizer machines as durable medical equipment
- Nebulizer medications and supplies
- Outpatient pulmonary rehabilitation programs
- Pulmonary function testing
- Hospital-administered breathing treatments (when inpatient under Part A)
What It Doesn't Cover
- Prescription inhalers (covered under Part D)
- Over-the-counter asthma medications
For nebulizers and pulmonary rehab, you pay 20% of the Medicare-approved amount after your $283 Part B deductible (2026).
Pulmonary Rehab Coverage
Medicare Part B covers outpatient pulmonary rehabilitation for chronic conditions including asthma, COPD, cystic fibrosis, emphysema, pulmonary fibrosis, sarcoidosis, and post-lung resection recovery.
Medicare Advantage (Part C)
Most plans include drug coverageMost Medicare Advantage plans include Part D prescription drug coverage, which means your inhaler coverage is built into your plan. Coverage follows the plan's formulary, similar to stand-alone Part D plans. Some Medicare Advantage plans may offer lower copays for certain inhalers or additional respiratory benefits.
Medicare Advantage plans also cover nebulizers and outpatient pulmonary rehabilitation, just like Original Medicare. However, you may need to use in-network providers and pharmacies to get the lowest costs.
What It Covers
- Prescription inhalers based on plan formulary (when Part D is included)
- Nebulizers and respiratory equipment
- Outpatient pulmonary rehabilitation
- May include additional respiratory or wellness benefits
What It Doesn't Cover
- Inhalers not on the plan's formulary
- Out-of-network pharmacy costs may be higher
Costs vary by plan. Review your plan's formulary and Summary of Benefits to understand your specific inhaler costs.

✦ Important: Formulary and Coverage Considerations
Your Inhaler Must Be on the Plan's Formulary
Each Medicare Part D plan maintains its own formulary (list of covered drugs). If your prescribed inhaler is not on your plan's formulary, you may need to pay the full retail price, request a formulary exception from your plan, or ask your doctor about a covered alternative. When choosing a Part D plan, always verify that your specific inhalers are listed.
If your plan denies coverage for a prescribed inhaler, you can request a coverage determination or exception. Your doctor can submit a letter explaining why the specific medication is medically necessary for you.
Part D Late Enrollment Penalty
If you do not enroll in a Part D plan when you are first eligible and go without creditable drug coverage for 63 or more consecutive days, you may face a [late enrollment penalty](/faqs/medicare-part-d-late-enrollment-penalty). This penalty is added to your monthly Part D premium for as long as you have Part D coverage. Even if you do not currently use inhalers or other medications, enrolling in a Part D plan protects you from this penalty.
Ways to Save on Asthma Inhalers under Medicare
Inhaler costs can add up quickly, especially if you use both a rescue inhaler and a maintenance inhaler. There are several strategies to reduce your out-of-pocket costs for asthma medications under Medicare.
Those with chronic asthma may also be eligible for chronic care management services through Medicare, which provides ongoing coordination of your care and can help ensure you are getting the most cost-effective treatment plan.
Tips to Reduce Your Inhaler Costs
- Ask your doctor about generic alternatives (e.g., generic Albuterol instead of brand-name Ventolin)
- Compare Part D plans during Annual Enrollment to find the best formulary for your inhalers
- Check manufacturer coupon programs for brand-name inhalers like Symbicort
- Use your plan's preferred pharmacy for the lowest copays
- Apply for Medicare Extra Help (Low Income Subsidy) if you have limited income
- Ask your pharmacist about pricing outside your insurance (gag clause eliminated)
- Consider a Medicare Advantage plan with built-in Part D that covers your specific inhalers
- Talk to your doctor about nebulizer treatment as a Part B-covered alternative
