Publication Summary

Why the Flu Is a Serious Health Risk for Medicare Beneficiaries

The flu, also known as influenza, is a contagious respiratory illness that spreads easily from person to person. For older adults and people with chronic health conditions such as diabetes, heart disease, or lung disease, the flu can be especially dangerous. It can lead to serious complications like pneumonia, which may require a hospital stay. Each year, thousands of older Americans are hospitalized due to flu-related complications. This is why flu prevention is a key focus of Medicare coverage and health guidance.

Your Medicare Flu Shot Coverage

Medicare Part B covers one flu shot per flu season. This benefit is available at no cost to you as long as your doctor, pharmacist, or other health care provider accepts Medicare assignment. You will not owe a deductible, copayment, or coinsurance for this service when it is provided by a participating Medicare provider. This makes it easy and affordable to get vaccinated every year without worrying about out-of-pocket costs.

Where You Can Get Your Flu Vaccine

Medicare beneficiaries have several convenient options for getting a flu shot. You can visit your primary care doctor, a local pharmacy, a health clinic, or a community vaccination event. Many pharmacies across the country accept Medicare directly, making it simple to get your shot while running errands. Be sure to bring your Medicare card and confirm that the provider accepts Medicare before getting vaccinated to ensure there is no charge to you.

Steps You Can Take to Prevent the Flu

Beyond getting vaccinated, there are everyday habits that can lower your chances of catching the flu. The publication highlights several simple but effective steps that anyone can follow during flu season.

• Wash your hands frequently with soap and water for at least 20 seconds.
• Use hand sanitizer when soap and water are not available.
• Avoid touching your eyes, nose, and mouth with unwashed hands.
• Stay away from people who are sick whenever possible.
• Cover your nose and mouth with a tissue or your elbow when you cough or sneeze.
• Clean and disinfect surfaces that are touched often, such as doorknobs and countertops.

Recognizing Flu Symptoms

The flu often comes on suddenly and feels different from a common cold. Symptoms of the flu include fever, chills, muscle aches, headache, fatigue, sore throat, runny or stuffy nose, and a cough. Some people may also experience vomiting and diarrhea, though this is more common in children. It is important to know the warning signs that mean you need immediate medical attention.

When to Seek Emergency Care

Certain flu symptoms are serious enough to require emergency care right away. The publication advises you to call 911 or go to an emergency room if you experience any of the following warning signs:

• Difficulty breathing or shortness of breath
• Persistent pain or pressure in the chest or abdomen
• Sudden dizziness or confusion
• Severe or persistent vomiting
• Flu symptoms that improve but then return with a worsening fever or cough

Treatment Options for the Flu

If you do come down with the flu, antiviral medications prescribed by your doctor can help reduce how long you are sick and make your symptoms less severe. These medicines work best when taken within the first 48 hours after symptoms begin, so it is important to contact your doctor as soon as you start feeling sick. Medicare may cover these medications depending on your specific plan, so check with your plan or pharmacist about your coverage.
