What is Medicare Part B and What Does it Cover?

What is Medicare Part B?

Medicare Part B (medical insurance) is part of Original Medicare. Original Medicare is comprised of Medicare Part A and Medicare Part B. It’s a federal health insurance program designed to provide and reduce the cost of health care services in the United States. If you are eligible for Medicare Part A, then you can also enroll in Medicare Part B.

Am I Eligible for Medicare Part B?

You are eligible for Original Medicare, including Medicare Part B, if you meet one of three criteria:

  • You’re aged 65 or older.
  • You’re younger than 65 with eligible disabilities by the Social Security Administration.
  • You have Amyotrophic Lateral Sclerosis (ALS) or End-Stage Renal Disease (ESRD).

What Does Medicare Part B Cover?

Medicare Part B covers preventative services and medically necessary services. This includes care to prevent an illness or detect it at an early stage – and services or supplies needed to diagnose or treat a medical condition.

Part B Medicare covers, but is not limited to:

  • Orthopedic, Cardiology, Radiology, and other specialists
  • Mental health services (inpatient, outpatient, and partial hospitalization)
  • Screenings for common medical conditions
  • Preventative care, including annual wellness checkups
  • Vaccinations (flu, pneumococcal, Hepatitis B, and more)
  • Clinical research
  • Ambulance services
  • Durable Medical Equipment (DME)
  • Limited outpatient prescription drugs

There are many tests, items, and services that are not covered by Medicare Part B. These include routine dental, vision, and hearing care – such as check-ups, eyeglasses or contact lenses, hearing aids, dental extractions, and dentures.

We recommend that you ask your provider if your medical service or procedure will be covered by your Medicare plan. Learn more about whether a test, item, or service is covered.

How Much is Medicare Part B?

What is the Medicare Part B Premium for 2022?

The standard Part B premium amount in 2022 is $170.10. Most people pay the standard Part B premium amount.

If your Modified Adjusted Gross Income (MAGI) as reported on your IRS tax return from two years ago is higher than a certain amount, you’ll pay the standard premium amount and an Income Related Monthly Adjustment Amount (IRMAA). IRMAA is an extra charge added to your standard premium.

Review the table below to see how much your monthly Part B premium will be – based on your income from two years ago.

The Part B premium will be automatically deducted from your benefit payment if you receive a Social Security, Railroad Retirement Board, or Office of Personnel Management benefit. If you don’t receive these benefits, you’ll receive a monthly or quarterly premium invoice.

How to Appeal a Medicare Part B IRMAA Adjustment

There are some situations where you can appeal an IRMAA adjustment. These include having the IRMAA based on a tax amount that is inaccurate or out-of-date, or one of seven life-changing events.

Seven life-changing events:

  • Death of spouse
  • Marriage
  • Divorce or annulment
  • Work reduction
  • Work stoppage
  • Loss of income from income-producing property
  • Loss or reduction of certain kinds of pension income

When any of these occur, you can request an appeal in writing by completing a request for reconsideration form with the Social Security Administration. You can also call the Social Security Administration at 1-800-772-1213.

Reducing Your Medicare Part B Premium

Looking for ways to reduce your Medicare Part B premium? If you are lower-income and meet specific criteria you may qualify for a Medicare Savings Program. There are three programs (Qualified Medicare Beneficiary Program, Specified Low-Income Beneficiary Program, and Qualifying Individual Program) that could help you pay for all or most of your Medicare Part B premium.

Also, some Medicare Advantage plans can reduce the cost of the Part B premium through a give-back benefit.

To see if you qualify for a Medicare Savings Program or a give-back benefit, speak to a local licensed Connie Health agent who can help you navigate your Medicare journey. Call (623) 223-8884 (TTY: 711).

What is the Medicare Part B Deductible for 2022?

Your Medicare Part B costs also include an annual deductible. In 2022, the Part B deductible is $233.

Medicare Part B and Coinsurance/Copayments

After your deductible is met ($233 in 2022), you pay 20% of the Medicare-approved amount for most doctor services, outpatient therapy, and durable medical equipment.

Original Medicare does not have a maximum on these out-of-pocket expenses. This is why most Medicare enrollees have either Medicare Supplemental insurance plus their Medicare prescription drug coverage (Medicare Part D plan). Or they choose to enroll in a Medicare Advantage Prescription Drug Plan, which covers all these needs.

Your Medicare Coverage Options

When to Apply for Medicare Part B

Know your Initial Enrollment Period

You are first eligible for Medicare during your Initial Enrollment Period. For most, the Initial Enrollment Period begins three months before your 65th birthday, the month you turn 65, and ends three months after your 65th birthday. You have this seven-month window to enroll in Medicare.

Medicare eligibility quiz

Should you miss your Initial Enrollment Period, you can enroll in Medicare Part B during the General Enrollment Period (January 1 – March 31), or a Special Enrollment Period, if you qualify.

Instances when you’re automatically enrolled in Original Medicare

  • When you’re already receiving Social Security benefits, you’ll be automatically enrolled in Medicare Parts A & B starting the first day of the month you turn 65.
  • If you are younger than 65 with an eligible disability by the Social Security Administration, the Initial Enrollment Period does not apply to you. You will automatically receive Medicare Parts A & B after receiving disability benefits from the Social Security Administration for 24 months.
  • Have Amyotrophic Lateral Sclerosis or End-Stage Renal Disease? You’ll automatically get Medicare Part A and Part B the month your disability benefits begin.

Can I Delay Enrolling in Medicare Part B?

You can turn down or delay Medicare Part B enrollment. If you decide to enroll later on, your coverage could be delayed. And if you don’t have creditable coverage during that time, you may pay a late enrollment penalty.

Agent tip:

“If you decline Part B and don’t have creditable coverage, you could pay a late enrollment penalty that lasts as long as you have Medicare Part B.“

This penalty will be added to your Part B premium as long as you have Medicare Part B. The penalty could cause your premium to increase up to 10 percent for each year you were eligible for Part B and chose not to sign up – unless you qualify for a Special Enrollment Period.

Want to be sure that it’s the right time to enroll in Medicare Part B? Speak to a local licensed Medicare agent who can help you make the best decision for your health and finances. Call (623) 223-8884.

Not Yet Retired?

Suppose you are not retired and receive benefits from the Social Security Administration or Railroad Retirement Board at least four months before turning 65. You’ll need to sign up with the Social Security Administration to get Medicare Part A.

If you have private health insurance through your or your spouse’s employer, you can choose to delay Medicare Part B until you retire and receive Social Security benefits.

Considerations for delaying signing up for Medicare Part B:
  • Most people pay a Medicare Part B premium. Determine whether it’s more cost-effective to be on Medicare Part B on your or your spouse’s private health insurance coverage.
  • Your employer-based health insurance company may offer similar coverage to Part B medical insurance.
  • You should check with your group health insurance plan administrator about how your health plan works with Medicare coverage – see what happens once you’re Medicare eligible.

End-Stage Renal Disease

You can enroll in Parts A & B if you’re eligible for Medicare because of End-Stage Renal Disease. You can choose whether or not to sign up for Part B. However, you’ll need Parts A & B to cover certain services under Medicare, including dialysis and kidney transplant services.
