Medicare Covers Paxlovid at No Cost to You

Yes, Medicare covers Paxlovid (nirmatrelvir/ritonavir), the antiviral medication used to treat COVID-19 in people at high risk of severe illness. You pay nothing out of pocket for the drug itself — no copay, no coinsurance, no deductible. This coverage applies to all three parts of Medicare: Original Medicare (Part A and B), Medicare Advantage (Part C), and Medicare Part D plans.

The catch is timing: Paxlovid must be started within five days of your first COVID-19 symptom. If you wait longer, the medication is less effective and may not be covered. You also need a prescription from a doctor, nurse practitioner, or physician assistant — you cannot buy it over the counter.

Key Takeaways

  • Medicare covers the full cost of Paxlovid with no copay or deductible, whether you have Original Medicare or a Medicare Advantage plan.
  • You must start Paxlovid within five days of your first COVID-19 symptom for it to work and be covered.
  • You need a prescription from a doctor or nurse practitioner; Paxlovid is not sold over the counter.
  • If you test positive at home, call your doctor the same day to request a prescription rather than waiting for an appointment.
  • Pharmacies sometimes run out of stock, so ask your doctor to call the prescription in when ready rather than sending it electronically.

How to Get a Paxlovid Prescription Under Medicare

Call your primary care doctor, nurse line, or urgent care clinic as soon as you test positive for COVID-19. Tell them you have tested positive and ask for a Paxlovid prescription. Do not wait for a scheduled appointment — same-day phone or video visits are common for this reason, and many practices can send a prescription to your pharmacy without seeing you in person.

If you do not have a primary care doctor, call your local urgent care center or emergency room. Retail clinics inside pharmacies (CVS MinuteClinic, Walgreens, etc.) can also prescribe Paxlovid. Some areas also have COVID-19 hotlines run by the health department that can connect you to a prescriber.

Once you have a prescription, take it to any pharmacy that stocks Paxlovid. Ask your doctor to call it in by phone rather than sending it electronically — pharmacies sometimes run out, and a phone call lets the pharmacist tell your doctor right away if they need to try a different location.

What Paxlovid Costs and What Medicare Pays

The retail price of a five-day course of Paxlovid is roughly $700 to $900 before insurance, depending on the pharmacy. Medicare pays the full amount. You will see $0 as your out-of-pocket cost at the pharmacy counter.

This coverage is separate from your regular deductible and does not count toward your deductible. It does not matter whether you have met your annual deductible or not — Paxlovid is covered in full from the first dose.

If a pharmacy tries to charge you a copay, ask the pharmacist to check your Medicare coverage again. This is usually a billing error. If the error persists, call Medicare directly at 1-800-MEDICARE (1-800-633-4227) and report the pharmacy name and location.

Who Can Receive Paxlovid Under Medicare

Medicare covers Paxlovid for any Medicare beneficiary with a confirmed COVID-19 infection who is at high risk of severe illness. High risk includes people age 65 and older (which covers most Medicare beneficiaries by definition), people with weakened immune systems, people with chronic kidney disease, chronic heart disease, chronic lung disease, or diabetes, and people who are pregnant or recently pregnant.

You do not have to prove you meet these criteria — your doctor makes that judgment when you call with a positive test. If your doctor says you do not meet the criteria, you can ask for a second opinion from an urgent care doctor or call your state health department for guidance.

Paxlovid is also covered for people who have had COVID-19 before. Reinfection is common, and Medicare covers treatment each time you test positive within five days of symptoms.

What Happens If You Miss the Five-Day Window

Paxlovid loses effectiveness after five days of symptoms. If you test positive on day six or later, your doctor may still prescribe it, but Medicare coverage becomes less certain and the medication is unlikely to prevent severe illness.

The five-day clock starts on the day your first symptom appeared, not the day you tested. If you develop a cough on Monday but do not test until Wednesday, you have three days left to start Paxlovid, not five.

If you are unsure when your symptoms started, tell your doctor the earliest day you remember feeling sick. Your doctor can then decide whether Paxlovid is still worth prescribing.

Paxlovid and Other Medications You Take

Paxlovid can interact with many common medications, especially blood thinners, heart medications, and cholesterol drugs. Before you fill a Paxlovid prescription, give your pharmacist a complete list of all medications and supplements you take — including over-the-counter drugs and vitamins.

Your pharmacist will check for interactions and tell your doctor if there is a problem. Sometimes your doctor will pause one of your regular medications for the five days you take Paxlovid, then restart it after you finish. This is normal and safe.

Do not skip doses of your regular medications without talking to your doctor first. If you are unsure whether an interaction is serious, call your pharmacist or doctor before you start Paxlovid.

Where to Find Paxlovid If Your Pharmacy Is Out of Stock

Call ahead before you go to the pharmacy. Ask whether they have Paxlovid in stock and how many doses. If they do not, ask them to check nearby locations or to order it for you.

You can also use the pharmacy locator on the U.S. Department of Health and Human Services website (hhs.gov) to find pharmacies near you that carry Paxlovid. Search by your zip code and select "Paxlovid" from the medication list.

If multiple pharmacies in your area are out of stock, ask your doctor to prescribe a different antiviral medication instead. Other options include molnupiravir (Lagevrio) and remdesivir (Veklury), both of which are also covered by Medicare at no cost.

Frequently Asked Questions

Do I need to be hospitalized to get Paxlovid?

No. Paxlovid is for people who are sick at home and want to prevent their illness from becoming severe. You take it as pills at home for five days. If you are already in the hospital, you may receive remdesivir (an IV medication) instead.

Can I get Paxlovid if I am vaccinated?

Yes. Vaccination does not prevent you from catching COVID-19, and Paxlovid is covered for any Medicare beneficiary who tests positive and is at high risk, regardless of vaccination status.

What if I have a bad reaction to Paxlovid?

Call your doctor right away. Common side effects include altered taste, nausea, and diarrhea, which usually go away after you finish the medication. Serious side effects are rare but can include allergic reactions or severe liver problems. Your doctor can tell you whether to stop taking it.

Does Paxlovid prevent long COVID?

Studies suggest Paxlovid may reduce the risk of long COVID symptoms, but it is not may provide to prevent them. It is most effective at preventing hospitalization and death in people at high risk.

Can I get Paxlovid more than once?

Yes. If you test positive again later, you can receive another course of Paxlovid. Medicare covers it each time, as long as you start within five days of symptoms.
