Medicare Part B costs will vary depending on a person’s income.

Medicare Part B is the portion of Medicare that covers medical appointments, such as doctor’s visits, and some medical equipment. Unlike Medicare Part A, Part B has a monthly premium regardless of a person’s work history.

This article will cover Medicare Part B-related costs, including how Medicare adjusts the monthly premium based on a person’s income.

A person’s income may affect the cost of Medicare Part B.

A person can enroll in Medicare Part B when they qualify for Medicare. Qualification is usually when a person reaches 65 years of age.

Enrollment is usually automatic if a person receives retirement benefits from the Social Security Administration or the Railroad Retirement Board. Before a person’s 65th birthday, Medicare will send them a membership card and details of their plan.

If a person is not currently receiving retirement benefits, they can enroll with Medicare through the Social Security Administration as early as 3 months before they turn 65 years old. Applying as early as possible can ensure that the benefits start on time.

If a person waits and applies 3 months after they turn 65 years old, they may have to pay a penalty in addition to their Medicare Part B premium.

Some people may qualify for Medicare at an earlier age if they meet the following criteria:

  • their doctor declares that they have a disability, and they receive Social Security disability benefits
  • they have end stage renal disease
  • they have amyotrophic lateral sclerosis

Under these circumstances, a person may enroll in Medicare Part B at an earlier time. If they qualify based on a disability or end stage renal disease, they may have to wait a certain amount of time before they can enroll in Part B.

We may use a few terms in this piece that can be helpful to understand when selecting the best insurance plan:

  • Deductible: This is an annual amount that a person must spend out of pocket within a certain time period before an insurer starts to fund their treatments.
  • Coinsurance: This is a percentage of a treatment cost that a person will need to self-fund. For Medicare Part B, this comes to 20%.
  • Copayment: This is a fixed dollar amount that an insured person pays when receiving certain treatments. For Medicare, this usually applies to prescription drugs.

Part B monthly premiums may vary from year to year. The standard premium in 2021 is $148.50 per month, but a person may have to pay more based on their regular income.

Medicare will notify a person on an annual basis of how their Medicare Part B premium may change for the following year.

If a person receives a benefit check, the Social Security Administration or Railroad Retirement Board will deduct this amount automatically, so it is not necessary to remember to pay Medicare each month.

Paying a monthly Part B premium does not mean that medical services are free of charge. A person will also need to pay deductibles and coinsurances for certain services.

Under traditional Medicare, a person’s Part B deductible is $203 per year. After they have met this deductible, a person will usually pay 20% of the Medicare-approved amount for most physician services, therapies, and durable medical equipment.

Some people may choose to obtain their insurance coverage under Medicare Advantage, or Medicare Part C.

Medicare Advantage, wherein a person will need to choose a private insurance company to administer their plan, is an alternative to traditional Medicare.

When someone chooses Medicare Advantage, they will still pay a monthly Part B premium, but their out-of-pocket costs may differ based on their chosen plan. In addition to the Part B premium, a Medicare Advantage premium may also apply.

Some people may pay more (or less) for their monthly premium based on their income. An estimated 7% of those receiving Medicare benefits pay an income-adjusted monthly premium.

Medicare determines a person’s income-related monthly adjustment based on the income they reported to the Internal Revenue Service 2 years prior. For 2021, this means that Medicare will consider a person’s modified adjusted gross income from 2019.

The income adjustment will depend on which type of tax return an individual has filed, be it individual or joint.

Sometimes, a person may receive additional help in paying for their Medicare premiums. If a person is eligible for Medicaid, for example — which is a state-funded insurance assistance program — this may help them pay their Part B premiums.

A person receives Medicaid based on their income level, and Medicaid qualifications may vary based on the state’s rules.

More information about Medicaid and its state-by-state income requirements are available on its website.

Medicare Part B costs include a standard monthly premium, deductible, and coinsurance. The deductible and coinsurance may vary if a person has a Medicare Advantage plan.

If a person’s income exceeds a certain amount, they may pay a higher premium based on income adjustments.

Individuals may receive help to pay their Part B premiums if they qualify for Medicaid benefits under their state’s rules.
