Medicare covers RSV prevention and treatment, but the scope depends on which part of Medicare you have and your specific situation

Respiratory syncytial virus (RSV) is a common respiratory infection that can be serious for older adults. Medicare Part B covers doctor visits, hospital stays, and lab tests related to RSV diagnosis and treatment. If you need a monoclonal antibody shot to prevent RSV — a newer preventive option — Medicare Part B also covers that, though your doctor must order it and you may have a copay or coinsurance. Medicare Part D (prescription drug coverage) covers antiviral medications if prescribed, depending on your plan's formulary.

The key difference is between treatment (which Medicare covers broadly) and prevention (which is covered but only under specific conditions). Most people with RSV recover at home with supportive care, which Medicare does not cover. Hospital or skilled nursing facility care for severe RSV is covered under Part A if you meet admission requirements.

Key Takeaways

  • Medicare Part B covers doctor visits, tests, and hospital care for RSV diagnosis and treatment at no more than your standard copay or coinsurance.
  • RSV prevention shots (monoclonal antibodies like Arexvy and Abrysvo) are covered by Medicare Part B for adults 60 and older, though you pay coinsurance after your deductible.
  • Antiviral medications for RSV are covered under Medicare Part D if your plan includes them on its formulary, but coverage varies by plan.
  • Home care for mild RSV (rest, fluids, over-the-counter fever reducers) is not covered by Medicare; only medical services ordered by a doctor are covered.
  • If RSV leads to hospitalization or skilled nursing care, Medicare Part A covers the facility stay if you meet the admission criteria.

What Medicare Part B Covers for RSV

Medicare Part B covers the medical services you need if you have RSV: office visits with your doctor, urgent care or emergency room visits, lab tests to confirm RSV, chest X-rays, and oxygen therapy if prescribed. You pay 20 percent coinsurance after you meet your Part B deductible (which is $240 in 2024, though this amount changes yearly).

If your doctor sends you to the hospital because of RSV, Medicare Part A (hospital insurance) takes over and covers your inpatient stay. Part A has a different deductible and cost structure — you pay a deductible per hospital stay, then Medicare covers most costs. If RSV leads to pneumonia or other complications requiring hospitalization, Part A covers that too.

Telehealth visits for RSV symptoms are also covered by Medicare Part B at the same rate as in-person visits, which can be useful if you are too ill to travel or want to avoid spreading the virus.

RSV Prevention Shots and Medicare Coverage

Two RSV prevention vaccines are now available for adults 60 and older: Arexvy (made by GSK) and Abrysvo (made by Pfizer). Both are single-dose shots given as an injection. Medicare Part B covers both vaccines for adults 60 and older at no cost for the vaccine itself — you pay nothing for the shot. However, you do pay coinsurance (typically 20 percent) for the administration fee, which is the cost of the doctor or nurse giving you the shot. This administration fee usually runs $15 to $30 depending on where you receive it.

Your doctor must order the vaccine, and you receive it in a doctor's office, clinic, or pharmacy that participates with Medicare. You do not need to meet any other conditions — age 60 or older is the only requirement. If you have already had RSV, you can still receive the vaccine. One shot provides protection for the RSV season (typically fall and winter in the Northern Hemisphere).

If you have a Medigap or Medicare Advantage plan, check with your plan first, as some plans may cover the administration fee differently or have preferred locations where you should receive the vaccine.

Antiviral Medications Under Medicare Part D

If your doctor prescribes an antiviral medication for RSV — such as baloxavir marboxil (Xofluza) — Medicare Part D (prescription drug coverage) may cover it. Coverage depends on whether the medication is on your specific plan's formulary (the list of drugs the plan covers) and which tier it is placed on. Tier placement determines your copay: a drug on Tier 1 might cost $5 to $10, while a Tier 3 or Tier 4 drug could cost $40 to $100 or more.

Not all Medicare Part D plans cover RSV antivirals, and some may require prior authorization from your doctor before they will pay. Contact your Part D plan directly or check your plan's formulary online to find out whether the medication your doctor wants to prescribe is covered and what your out-of-pocket cost will be.

If you do not have Part D coverage, you can still receive the medication, but you pay the full pharmacy price out of pocket. Some pharmacies offer discount programs that may lower the cost.

Skilled Nursing and Rehabilitation Care After RSV

If RSV causes complications that require you to stay in a skilled nursing facility (SNF) for rehabilitation — for example, if you need physical therapy to regain strength after a severe infection — Medicare Part A covers the SNF stay. You must be admitted to the hospital first for at least three consecutive days (not counting the day you are discharged), and your doctor must order the SNF care as medically necessary.

Medicare Part A covers up to 100 days in a skilled nursing facility per benefit period. You pay nothing for days 1 through 20, and then $200 per day (in 2024) for days 21 through 100. After 100 days, you pay all costs yourself unless you may have access to for Medicaid.

Home health care ordered by your doctor after an RSV hospitalization is also covered by Medicare Part A if you are homebound and need skilled nursing or therapy services. This is different from general home care or information with daily living, which Medicare does not cover.

What Medicare Does Not Cover for RSV

Medicare does not cover over-the-counter medications like acetaminophen, ibuprofen, cough syrup, or saline nasal drops — even if you use them to manage RSV symptoms. You pay for these yourself at the pharmacy or store.

Routine home care for mild RSV — such as rest, fluids, and monitoring at home — is not a covered service. Medicare only covers medical services ordered or provided by a licensed healthcare provider. If you are managing RSV at home without medical intervention, there is no Medicare coverage for that care.

Preventive care visits specifically to discuss RSV risk (without a diagnosis or symptoms) are not separately covered. However, if RSV prevention is discussed during an annual wellness visit, that visit itself is covered by Medicare Part B at no cost to you.

Medicare Advantage Plans and RSV Coverage

If you have a Medicare Advantage plan (Part C), your coverage for RSV is similar to Original Medicare but may have differences. Most Medicare Advantage plans cover doctor visits, hospital care, and tests for RSV at the same or lower out-of-pocket cost as Original Medicare. Some plans may have a copay instead of coinsurance, which can be easier to predict.

RSV prevention vaccines are covered by Medicare Advantage plans the same way they are under Original Medicare — the vaccine itself is free, and you pay for administration. However, some plans may steer you to specific pharmacies or clinics for the vaccine, so check your plan's details first.

If your Medicare Advantage plan includes Part D drug coverage, antiviral medications follow the same formulary and tier rules as standalone Part D plans. Call your plan's customer service number (on the back of your card) to confirm coverage before your doctor prescribes a medication.

Frequently Asked Questions

Do I have to pay anything for the RSV vaccine if I have Medicare?

You pay nothing for the vaccine itself. You do pay a copay or coinsurance (usually $15 to $30) for the administration fee — the cost of having a nurse or pharmacist give you the shot. If you have already met your Part B deductible for the year, you may owe less or nothing depending on your plan.

Will Medicare cover RSV treatment if I get sick at home?

Medicare covers doctor visits and tests to diagnose RSV, and any medications your doctor prescribes. It does not cover the cost of staying home, resting, or using over-the-counter remedies. If your symptoms are severe enough to need hospitalization, Medicare Part A covers the hospital stay.

What if my doctor prescribes an antiviral for RSV but my Part D plan does not cover it?

You can ask your doctor to request a prior authorization from your plan, which sometimes results in coverage. If the plan still denies it, you can pay out of pocket or ask your doctor about alternative medications that your plan does cover. Some pharmacies offer discount programs that may lower the cost.

Does Medicare cover RSV testing?

Yes. If your doctor orders an RSV test (usually a nasal swab or rapid antigen test), Medicare Part B covers it. You pay 20 percent coinsurance after your deductible. Many urgent care centers and doctor's offices can perform the test on the same day.

Can I get the RSV vaccine if I already had RSV?

Yes. Having had RSV in the past does not disqualify you from receiving the vaccine. Your doctor can still order it, and Medicare will cover it the same way. One dose provides protection for the current RSV season.
