The official Medicare Part B premium 2027 has not been announced yet. The Trustees project $209.50 a month, up $6.60 from $202.90 in 2026, with a $292 annual deductible. CMS usually publishes the final figure in November.
The Medicare Part B premium 2027 has not been officially announced yet, but the number to plan around is $209.50 a month. That is the 2026 Medicare Trustees Report projection, and it would be a $6.60 increase from the current $202.90. The Centers for Medicare and Medicaid Services, known as CMS, has announced the final figure in the middle of November in recent years, so the official Medicare Part B premium 2027 notice could land any day. The annual deductible is projected to rise from $283 to $292. Income-related surcharges, called IRMAA, will be published with the final numbers. Until then, treat every Part B figure on this page as an estimate. We will be updating this article monthly.
The timing matters because the Medicare Part B premium 2027 arrives right after Social Security announced a 3.6 percent cost of living adjustment on October 14, 2026. For the average retired worker, that raise is about $75 a month, taking the benefit from $2,095 to $2,170. Most retirees have their Part B premium deducted from that check, so the projected $6.60 increase would take back a small slice of the raise. Medicare open enrollment runs until December 7, which means people choosing between Original Medicare and a Medicare Advantage plan are making decisions before the final premium is confirmed. A separate $90 payment sent to many Medicare Part B enrollees in October has also pulled the topic into the political spotlight.

Has CMS Announced the Medicare Part B Premium 2027 Yet?
No official figure had been published at the time of writing. Several websites use the word announced in their headlines, but the pages themselves still describe $209.50 as a projection. We checked those pages, and each one says CMS has not released the premium, deductible, or IRMAA brackets. Because this article is built to be accurate, it treats the Medicare Part B premium 2027 as projected, not final, and it will be updated the day CMS publishes its fact sheet.
How good are these projections? The record is mixed but close. Last year the Trustees projected a 2026 premium of $206.50. The final number was $202.90, about $4 lower. So the real Medicare Part B premium 2027 could land a few dollars on either side of $209.50.
One deductible figure circulating online is about $310, and it comes from early actuarial estimates on a planning site. The Trustees Report number of $292 is the one cited by AARP and other major outlets, so that is the figure used here.
Projected Medicare Part B Premium 2027 and Deductible Compared
| Year | Standard monthly premium | Annual deductible |
|---|---|---|
| 2025 | $185.00 | $257 |
| 2026 | $202.90 | $283 |
| 2027 (projected) | $209.50 | $292 |
The 2026 jump was nearly 10 percent. The projected increase for 2027 is about 3.25 percent, much gentler. Still, the Medicare Part B premium 2027 is only one step on a longer path. The Trustees project the standard premium will reach $272.10 by 2031, which is 34.1 percent above today’s level and an average of about 6 percent a year.
KFF has put the annual picture in dollars. The standard premium costs $2,435 over 2026, and the projected 2027 change adds about $79 a year. KFF also reported that in 2024, about 12 percent of Part B enrollees, roughly 7.4 million people, spent more than 10 percent of their income on premiums.
Will the 3.6% COLA Cover the Medicare Part B Premium 2027?
For most people, yes, with room to spare. A 3.6 percent raise on an average benefit of $2,095 adds about $75 a month. Subtract the projected $6.60 increase and the typical retiree who pays the standard premium keeps roughly $68 more. That means the premium increase would use about 9 percent of the raise.
Last year was tighter. The 2026 COLA was 2.8 percent, worth about $56 a month on average, while the premium rose $17.90. Retirees kept about $38. That contrast explains why the Medicare Part B premium 2027 looks less painful at first glance, though advocates warn that premiums are claiming a growing share of each yearly raise. AARP’s Harriet Komisar made that point, noting that people will see premiums taking up a growing portion of each yearly increase.
The hold harmless rule
Federal law includes a hold harmless provision. It generally stops a Part B premium increase from shrinking your Social Security check. It applies to people who have the standard premium deducted from their benefit, which AARP says covers about 70 percent of enrollees.
It does not protect everyone. These groups can still see their net payment fall.
| Group | Why hold harmless may not apply |
|---|---|
| New Part B enrollees | Protection does not apply in the first year of enrollment |
| People who pay Medicare directly | No Social Security deduction to protect |
| Higher-income enrollees paying IRMAA | They pay more than the standard premium |
| People on Medicaid premium help | A state pays the premium, so rules differ |
The $90 Medicare Payment: What Happened and Who Got It
A one-time $90 payment was announced in early October 2026 as a Part B premium rebate. According to KFF, it was aimed at about 21 million people in traditional Medicare who do not pay income-related premiums or get Medicaid premium help. AARP puts the figure at 20.8 million. Most direct deposits were scheduled around October 8, and some people were told to expect a paper check later in October labeled as a Medicare Improvement Fund payment. Beneficiaries could call Social Security at 1-800-772-1213 starting October 15 to check on payment status.
The money came from the Medicare Improvement Fund, which holds just over $2 billion and had never been used by CMS. KFF noted that the payments would largely drain it. People in Medicare Advantage plans, roughly 35 to 36 million enrollees, were not eligible. Neither were people who pay IRMAA or live outside the country.
Critics say the payment is small next to rising costs. KFF’s Juliette Cubanski said it may not go far toward offsetting costs. Supporters see it as quick relief. Either way, it is a one-time payment and it does not change the Medicare Part B premium 2027.
2027 IRMAA Brackets: Projected Medicare Part B Surcharges
IRMAA stands for income-related monthly adjustment amount. It is added to the standard premium if your modified adjusted gross income from two years earlier is above a threshold. For 2027, Social Security uses your 2025 tax return. About 5.1 million beneficiaries paid IRMAA in 2025.
The brackets below are projections, not official. Analysts say individual thresholds could shift by about $1,000 once CMS publishes the final table. The surcharge amounts come from the Trustees Report.
| Single filers (2025 income) | Married filing jointly | Part B surcharge | Part D surcharge |
|---|---|---|---|
| $112,000 or less | $224,000 or less | None | None |
| $112,001 to $142,000 | $224,001 to $284,000 | $83.70 | $15.40 |
| $142,001 to $177,000 | $284,001 to $354,000 | $209.40 | $39.70 |
| $177,001 to $212,000 | $354,001 to $424,000 | $335.10 | $64.00 |
| $212,001 to $499,999 | $424,001 to $749,999 | $460.70 | $88.30 |
| $500,000 or more | $750,000 or more | $502.60 | $96.40 |
If you are married and file separately, the projected surcharge is $460.70 for Part B and $88.30 for Part D between $112,001 and $386,000, and $502.60 and $96.40 above $386,000.
Added to the standard premium, a single filer in the top bracket would pay about $712.10 a month for Part B if the Medicare Part B premium 2027 lands at $209.50.
If your income dropped because of retirement, a spouse’s death, divorce, or another life-changing event, you can ask Social Security to use a more recent year by filing Form SSA-44.
What the Medicare Part B Premium 2027 Means for Different Households
The Medicare Part B premium 2027 does not hit everyone the same way, so it helps to find your own situation.
Retirees with the premium deducted from Social Security. You are the most protected group. Your January 2027 check should still rise with the COLA, and the premium increase will simply shave a few dollars off the raise.
People turning 65 in 2027. You are new to Part B, so hold harmless does not apply in your first year. Expect to pay the full standard premium, and add IRMAA if your 2025 income was above the threshold. If you are still working and have employer coverage, ask your benefits office before you delay Part B, because late enrollment penalties can last for life.
Higher earners. Your bill depends on your 2025 tax return, not your current paycheck. A one-time capital gain, a Roth conversion, or the sale of a home can push you into a higher IRMAA bracket for 2027. If that happened to you, ask about the SSA-44 process early.
Medicare Advantage members. You still pay the Part B premium, usually through Social Security, even though your plan is run by a private insurer. Your plan may add its own premium, and Advantage members did not get the $90 payment. Before December 7, compare your plan’s 2027 costs with Original Medicare plus a Medigap policy.
People paying directly. Watch your quarterly bill. When CMS posts the final Medicare Part B premium 2027, your January or April statement should reflect the new amount. Setting up Easy Pay can prevent missed payments.
Other 2027 Medicare Costs Already Confirmed
Part D numbers are official. The standard deductible is $700, up from $615 in 2026. The out-of-pocket cap is $2,400, up from $2,100. The base beneficiary premium is $41.33 a month, up from $38.99.
The Part A hospital deductible is not official yet. The Trustees estimate $1,788, compared with $1,736 in 2026. As with the Medicare Part B premium 2027, CMS is expected to publish it in the same fall announcement.

How to Apply for Medicare Part B
If you are turning 65, your initial enrollment period lasts seven months and surrounds your birthday month. If you miss it, you can sign up during the general enrollment period from January 1 to March 31, though you may owe a late enrollment penalty of 10 percent for each full 12 months you could have enrolled. Most people apply through Social Security online, by phone, or at a local office. Have your Social Security number, birth date, and proof of any employer coverage ready. People who are already getting Social Security benefits at 65 are usually enrolled automatically.
Medicare Part B Processing Time
Social Security does not promise a single turnaround for every case. Your coverage start date depends on when you enroll relative to your initial enrollment period. Sign up before the month you turn 65 when possible, and check your status in your online my Social Security account. If you do not get a confirmation, call Social Security and ask for a written receipt.
Medicare Part B Premium Payment Schedule
If you receive Social Security, the premium is normally deducted from your monthly benefit. The 2027 amount takes effect in January 2027, which is also when the COLA first shows up. If you do not receive Social Security, Medicare bills you directly, usually every three months, and you can pay online, by mail, or through your bank’s bill pay. Medicare Easy Pay can draw it from a checking or savings account automatically. People who pay IRMAA get a determination letter, and they can appeal it.
