Will Medicare Cover the Flu Shot?

Review Medicare plan options with licensed insurance agents near you

Medicare covers the full cost of yearly flu shots. To get the shot for free, be sure to use a provider that accepts your plan's payment, whether you're enrolled in Original Medicare or a Medicare Advantage plan. You must use a plan provider if you have a Medicare Advantage HMO, but PPO members are covered for both in-network and out-of-network flu shots.

If a second flu season breaks out in the same calendar year, your doctor may recommend you get a second shot. Both Original Medicare and Medicare Advantage plans cover a second vaccine if your doctor approves it.

Since the flu vaccine is free with Medicare, the main difference between plans is where you can get the shot. You won't be charged for the shot as long as you use a provider covered by your plan.

Does Medicare pay for flu shots?

Medicare pays for the full cost of one flu shot each year. You don't need a doctor's approval, and you can get your shot from any health care provider or pharmacy that accepts Medicare.

Medicare may cover a second flu shot during the calendar year. This could happen if there are two separate flu seasons in the same year and your doctor recommends a second vaccine.

Medicare also provides free vaccines for other conditions, like COVID-19 and pneumonia, similar to its free flu shots.

Does Medicare Advantage cover flu shots?

Medicare Advantage plans cover flu shots the same way as Original Medicare. You can get a free flu vaccine once per calendar year from any provider covered by your plan.

You don't need a referral to get an annual flu vaccine, even with a Medicare Advantage HMO.

If there are two flu seasons within the same calendar year, Medicare Advantage plans cover a second vaccine if your doctor approves it.

To be sure you're covered, contact your Medicare Advantage plan to find out where you can go for your flu shot. With an HMO, for example, you need to stay within your plan's provider network. If you have a PPO, you can go to an out-of-network provider and still get the shot for free.

Choosing a Medicare Advantage plan

If you're shopping for a Medicare Advantage policy, flu vaccines should not be part of your decision since coverage is similar among plans. But a plan's overall performance and Medicare rating may be important to you.

When should I get a flu shot?

According to the Centers for Disease Control and Prevention (CDC), younger people can get the flu shot as early as July or August. But for older adults, getting the vaccine too soon can reduce its effectiveness later in the season.

If you're 65 or older, the CDC recommends getting the vaccine in September or October, before the flu begins to spread. But you can still be protected even if you get the vaccine in November or later.

Medicare covers the vaccine at any time during flu season.
