Medicare recipients will see a reduction in their Medicare Part B premiums for 2023.

2023 Medicare Parts A B premiums and deductibles

The Centers for Medicare and Medicaid Services (CMS) adjusts coinsurance, deductible, and premium amounts for Medicare Parts A and B each year. For many years, including in recent years, the premium and deductible for Medicare Part B have increased. Recently, CMS released the premium and deductible amounts for Part B for 2023.  

Lower Medicare Part B premiums for 2023 

Medicare recipients will see a reduction in their Medicare Part B premiums for 2023. The new monthly premium will be $164.90, a decrease of $5.20 per month. The lower premium is a welcome change after the jump that recipients experienced in 2022. The monthly premium for Part B in 2021 was $148.50 and skyrocketed to $170.10 in 2022 based on the CMS estimate of the cost of the drug Aduhelm, used to treat Alzheimer’s disease. However, the Medicare program spent much less than expected on the primary drug used to treat Alzheimer’s, and recipients in 2023 will get some relief as a result.

When do the changes to Medicare Part B premiums take effect? 

Although CMS has announced the new rates, people will not see changes in their premiums or deductibles until January 2023. The new premium and deductible will be in place for all of 2023. However, Medicare Open Enrollment begins October 15 and ends December 7, 2022. People who have Medicare Advantage are also affected by the change in Part B premiums and should check the premium and cost-sharing information that Medicare Advantage plan providers release ahead of open enrollment.

What is Medicare Part B? 

Medicare Part B is often called medical insurance, and it covers both preventive and medically necessary services. Most of the Part B care patients receive is outpatient care. Part B also covers durable medical equipment. Part B can also cover ambulance services, mental health services, and even some outpatient prescription drugs. As a result, Medicare recipients rely on Medicare Part B for a large portion of their healthcare.  

Other changes announced by the CMS for 2023 

The CMS announced other changes to Medicare for 2023. Most people in 2023 will pay the standard premium of $164.90. However, a Medicare recipient’s Part B premium is based on income. In 2023, there will be changes to the income-related monthly adjustment amounts (IRMAAs). The CMS estimates these changes will affect around seven percent of Medicare recipients. IRMAAs will rise from $91,000 in 2022 to $97,000 in 2023 for a single beneficiary. The amount for married people filing a joint tax return will increase from $182,000 in 2022 to $194,000 in 2023. This change in the IRMAAs will allow more people to take advantage of the standard rate rather than paying the next tier. The maximum premium for Medicare Part B in 2023 will be $560.50 for those with IRMAAs equal to or greater than $500,000.

Medicare’s Part B standard monthly premium will fall to $164.90 in 2023, a $5.20 decrease from 2022, the Centers for Medicare & Medicaid Services (CMS) announced on Sept. 27. The open enrollment period to make any changes to next year’s Medicare coverage begins on Oct. 15 and goes through Dec. 7.

The premium drop comes in the wake of the big 2022 increase, the largest dollar increase in the history of the program. Part B covers doctor visits, diagnostic tests and other outpatient services. Most Medicare beneficiaries have Part B premiums deducted directly from their monthly Social Security payments.


Next year’s premium decrease makes good on statements this year by Health and Human Services Secretary Xavier Becerra that the money Medicare was saving because spending on Aduhelm, a new Alzheimer’s drug, was not going to be as high as expected would be passed on to beneficiaries in 2023. Spending on other Part B services is also projected to be less than anticipated.

AARP had called on CMS to lower the Part B premium for 2022 after Aduhelm's manufacturer lowered the price and the agency approved the medication on a limited basis.

“Today’s announcement of lower Part B premiums and deductibles is welcome news for seniors who are struggling with rising costs due to inflation,” said Nancy LeaMond, AARP executive vice president and chief advocacy and engagement officer. “Reducing their Medicare expenses, combined with the expected cost of living adjustment for Social Security, will provide much-needed financial relief for older Americans.”

CMS also announced the premiums for those Medicare enrollees who pay higher monthly charges because of their income. Those charges will also decline. Part B beneficiaries with annual individual incomes greater than $97,000 will pay more than the standard premium — how much more will depend upon income. For example, someone filing an individual tax return whose income is between $97,000 and $123,000 will pay $230 a month for Part B. CMS says about 7 percent of Medicare beneficiaries pay more than the standard monthly premium.

Most Medicare enrollees must pay the Part B premium whether they have original Medicare or a private Medicare Advantage plan. Some Advantage plans offer a “giveback” benefit where the insurer covers part or all of a member’s Part B monthly premium. Consumers can find those plans on the Medicare plan finder. Deductibles in Medicare Advantage vary by plan.

Part B deductible lower

The annual Part B deductible for 2023 is also decreasing, to $226, a $7 decline. And beginning July 1, Medicare enrollees who take their insulin through a pump as part of the Part B durable medical equipment benefit will not have to pay a deductible. Under the new Inflation Reduction Act of 2022 , cost sharing for insulin will be capped at $35 a month next year.

Part A costs increase

While most Medicare enrollees do not pay a monthly premium for Part A, which covers inpatient hospital, skilled nursing facility, hospice and some home health care services, there is a deductible charged for each hospital stay.

For 2023, the Part A deductible will be $1,600 per stay, an increase of $44 from this year. For those people who have not worked long enough to qualify for premium-free Part A, the monthly premium will also rise. The full Part A premium will be $506 a month in 2023, a $7 increase. Whether a beneficiary has to pay the full Part A premium depends on their or their spouse’s work history. Beneficiaries with Medicare Advantage plans should check with their plan for hospital charges.
