Everything You Need to Know about Medicare Part B

Medicare Part B is a federal health insurance program that covers a range of medical services and supplies. Here's what you need to know about this program:

What Medicare Part B Covers

Medicare Part B covers a variety of medical services, including doctor visits, outpatient care, preventative services, and durable medical equipment. It also covers some diagnostic tests and procedures, mental health care, and certain medications administered in a medical setting.

How You Can Enroll for Medicare Part Part B 

If you're turning 65 and receiving Social Security benefits, you'll be automatically enrolled in Medicare Part B. If you're not receiving Social Security benefits, you'll need to sign up for Part B during your initial enrollment period, which is the three months before and after your 65th birthday.

Premiums: Most people who enroll in Medicare Part B will need to pay a monthly premium. The cost of the premium can vary based on your income, but for most people, it's $148.50 per month in 2021.

Deductibles and Coinsurance: Medicare Part B has an annual deductible of $233 in 2021. After you meet your deductible, you'll typically pay 20% of the Medicare-approved amount for most services covered by Part B.

Coverage Gaps: Medicare Part B does not cover everything, so you may need to pay out-of-pocket for certain services and supplies. For example, Part B does not cover routine dental care, hearing aids, or long-term care.

Supplemental Coverage: Some people choose to enroll in a Medicare Supplement plan (also called Medigap) to help cover the costs of deductibles, coinsurance, and other out-of-pocket expenses associated with Part B. Others opt for a Medicare Advantage plan, which provides all-in-one coverage for both Part A and Part B services.

Important Dates: It's important to be aware of key dates related to Medicare Part B, such as your initial enrollment period, annual enrollment period, and special enrollment periods. These periods can impact when you can enroll or make changes to your coverage.

Medicare Part B Benefits

Medicare Part B offers several benefits to individuals who are eligible for the program. Here are some of the key advantages of enrolling in Medicare Part B:

Access to Preventive Services: Medicare Part B covers a range of preventive services, such as annual wellness visits, flu shots, mammograms, and screenings for various medical conditions. These services can help detect health issues early and prevent more serious problems down the line.

Coverage for Medically Necessary Services: Part B covers a wide range of medically necessary services, including doctor visits, outpatient care, and durable medical equipment. This coverage can be particularly important for individuals with chronic conditions or those who require ongoing medical care.

Protection Against High Out-of-pocket Costs: Medicare Part B has an annual deductible and coinsurance, but these costs are capped, which can help protect individuals against high out-of-pocket expenses. Additionally, individuals can purchase supplemental insurance, such as a Medicare Supplement plan, to help cover these costs.

Flexibility to See Any Provider who Accepts Medicare: With Medicare Part B, individuals have the flexibility to see any healthcare provider who accepts Medicare. This means that they can choose their preferred doctors, hospitals, and other healthcare providers without needing a referral or prior authorization.

Peace of Mind: Enrolling in Medicare Part B can provide peace of mind, knowing that you have access to affordable medical care when you need it. It can also help protect against unexpected medical expenses that could be financially devastating without insurance coverage.


Overall, Medicare Part B provides important coverage for a range of medical services and supplies. If you're approaching age 65 or have questions about your Medicare coverage options, it's a good idea to talk to a licensed insurance agent or healthcare professional to determine the best course of action for your individual needs.
