The standard Medicare Part B premium increased to $174.70 per month in 2024, up from $164.90 in 2023.

The premium also increased for higher income earners who pay an income-related monthly adjustment amount (IRMAA), with the most expensive Part B premium increasing from $560.50 per month in 2023 to $594.00 per month in 2024.

This guide helps to explain why the Medicare Part B (medical insurance) premium typically will go up each year, as well as some ways you may be able to save on some of your out-of-pocket Medicare costs.

Does the Medicare Part B premium go up every year?

The Part B premium is hardly the only Medicare cost that may go up every year.

The Medicare Part A (hospital insurance) premium also typically increases annually for those who are required to pay it. Medicare Part A and Part B deductibles typically increase each year, as well.

Medicare Part B coinsurance costs tend to remain steady at 20 percent of the Medicare-approved amount for a medical service or item.​

There are a number of contributing factors to why Medicare costs go up each year, such as:

• Close to 10,000 Americans become eligible for Medicare every single day.²
  
  
• Americans are living longer, and therefore requiring more years of health care.
  
  
• As the population ages, the ratio of employed workers (who support Medicare through taxes) to retirees (who receive the benefits from those taxes) continues to shrink.
  
  
• The cost of health care continues to rise.

When you add it all up, you have fewer people paying Medicare taxes that support an increasing number of Medicare beneficiaries who are themselves living longer and being charged more for their care.

Increasing the Part A and Part B premiums is one way that these rising costs are partially addressed.

How is Medicare paid for?

Most Medicare Part A and Part B funding comes from general revenue, which consists mostly of federal income taxes.

While Medicare Part A is funded through payroll taxes and other sources through what's called the Hospital Insurance (HI) Trust Fund, Medicare Part B is mostly funded by outlays from Congress and the premiums beneficiaries pay.

Increasing the Part B premium by only a small percentage for each beneficiary can raise tens of millions of dollars for the Medicare program.

What is the Medicare Hold Harmless Rule?

Your Medicare premiums aren’t the only thing that will go up each year: your Social Security benefit payment will typically also increase each year.

The Social Security Administration (SSA) uses the consumer price index for workers (CPI-W) to make annual adjustments to benefit payment amounts. This is called the cost of living adjustment, or COLA, and is a way to help benefit payments keep up with the cost of living.

The cost of health care often rises faster than inflation, however. Fortunately, the “hold harmless” rule prevents Medicare premiums from increasing by a higher amount than the Social Security COLA.

The hold harmless rule does not apply to you, however, if:

• This is your first year receiving Medicare Part B benefits
• You are enrolled in a Medicare Savings Program (MSP)
• You pay an IRMAA
• You were enrolled in an MSP in 2023 but lost program coverage because your income increased

If you pay a Part B late enrollment penalty, your penalty cannot be waived as part of the hold harmless rule. In fact, your late enrollment penalty will increase according to how much the Part B premium will go up each year.

Are there ways to save on my Medicare out-of-pocket costs?

If you’re concerned about the rising cost of Medicare, you can consider a few options that may be able to help you save on your out-of-pocket Medicare costs:

• Medicare Savings Programs are available to qualified Medicare beneficiaries who have limited incomes and financial resources. These programs can help cover specific Medicare premiums, deductibles and/or coinsurance costs.
  
  
• Medicare Supplement Insurance plans (also called Medigap) can provide coverage for certain Medicare out-of-pocket expenses. While Medigap plans don’t cover the Part B premium, some plans may help cover the Medicare Part B deductible, copayments and other expenses.
  
  
• Medicare Advantage plans (Medicare Part C) provide all the same benefits as Medicare Part A and Part B (Original Medicare) and may offer benefits not available in Original Medicare. You must still pay your Medicare Part B premium, but the money you can potentially save on other covered health care costs can help you better afford your Part B premium.
