Medicare 2027 Costs and Premiums: What to Know Before Choosing Your Health Plan

Medicare 2027 Costs and Premiums: Medicare 2027 costs are coming into focus on the first day of open enrollment, and the picture is more uneven than the headline premium numbers suggest. Last week CMS announced a one-time $90 payment for people in Original Medicare who pay the standard Part B premium, aimed at more than 20 million enrollees. It will not reach everyone. Medicare Advantage members are excluded, and so are higher earners and people who already get help from their state. The money comes from the Medicare Improvement Fund, which holds about $2 billion, and the Medicare Rights Center notes it is not a true premium refund. The standard Part B premium itself is still a projection. The Medicare Trustees put it at $209.50 a month for 2027, up from $202.90, and CMS is expected to confirm the figure in November. Private forecasters have floated numbers as high as $221, so treat any single estimate as a planning range. We will be updating this article monthly.

The bigger decision sits behind the premium: which kind of coverage protects your budget in a bad year. For 2027, the federal ceiling on in-network spending in Medicare Advantage rises to $9,850, up $600 from $9,250. Original Medicare still has no ceiling at all. People who buy a Medigap policy to fill that gap face their own pressure. KFF Health News reported double-digit rate increases becoming routine, with some Plan G filings in early 2026 rising from just over 12 percent to more than 26 percent. That means the cheapest plan in October may not be the cheapest by next summer. This guide compares total yearly cost for four realistic health scenarios, lays out every date and deadline, and includes a calculator so you can run your own numbers before December 7.

Medicare 2027 Costs and Premiums Key Highlights

Medicare Part B Premium Outlook: Where the Number Is Heading

The 2026 premium jumped 9.7 percent, or $17.90, and became the first to top $200. That implies a 2025 premium of about $185. The Trustees’ newest projection is gentler for 2027, at $6.60 or roughly 3.25 percent, but their longer view is less comfortable. They expect the premium to grow about 6 percent a year from 2026 through 2031, reaching $272.10 a month. That would be a 34 percent increase over today’s $202.90.

Social Security raises are not expected to keep pace. The Trustees assume cost-of-living adjustments averaging 2.4 percent a year from 2027 to 2031. A $2,080 monthly benefit would grow to about $2,340 by 2031 under that path, while Part B would take a larger share each year. AARP’s analysis found that projected premium growth of about $69 over five years would absorb more than a quarter of the $260 in COLA gains.

Some people have a buffer. The hold harmless rule prevents a Part B increase from shrinking your Social Security check below last year’s amount. It will likely protect only part of the 2027 increase for most people, and roughly 30 percent of Part B enrollees are not covered by it. That group includes people who do not receive Social Security checks and people who pay income-related surcharges. About 5.1 million beneficiaries paid those surcharges in 2025. KFF also found that 7.4 million Part B enrollees, about 12 percent, spent more than 10 percent of their income on premiums in 2024.

Forecast differences matter here. The Trustees’ figure of $209.50 comes from a government report. Some private projections run higher, near $215 to $221 for the premium and about $310 for the deductible. If you are budgeting tightly, use the higher number as a cushion until CMS publishes final amounts.

Medicare Part D 2027: Your Drug Costs, Plan Changes and Enrollment Deadline

Medicare Plans 2027: What Changes on January 1 and What You Will Pay

$90 Medicare Payment: Who Gets It and Who Does Not

CMS described the payment as a premium rebate, and it is aimed at people in Original Medicare Part B who pay the standard premium and do not receive state help with their premiums. It will be sent automatically by direct deposit, and the announcement did not describe an application. Medicare Advantage members do not qualify even though they pay the same Part B premium. Higher earners paying an income-related premium are also excluded. As of this writing, no payment date has been published.

There are two practical points. First, do not respond to calls or texts offering to speed up or confirm a $90 payment. Medicare does not ask for bank details by phone, and the payment is described as automatic. Second, the funding comes from a fund that would be largely depleted after the payments, so it should be treated as a one-time event and not a new benefit. For most households it offsets less than half of one month’s Part B premium.

Part A Costs in 2027: The Hospital Bill Most Budgets Forget

Most people pay no premium for Part A because they or a spouse worked at least 40 quarters. Part A still carries cost sharing, and in Original Medicare it can be the largest single bill of the year. The projected deductible for 2027 is $1,788 for each benefit period, up $52 from $1,736. A benefit period starts when you enter a hospital and ends after you have been out of a hospital or skilled nursing facility for 60 days in a row, so two admissions in one year can mean two deductibles.

After day 60 of a stay, daily coinsurance applies. In a skilled nursing facility, you pay nothing for the first 20 days after a qualifying hospital stay, and the projected 2027 coinsurance is $223.50 a day for days 21 through 100. After day 100 you pay all costs. For someone who needs 60 days of rehabilitation after a hospital stay, the skilled nursing coinsurance alone would be about $8,940 (40 days at $223.50), on top of the hospital deductible. Medigap Plan G and similar plans cover most of this. Medicare Advantage plans set their own copays, which often start the daily charge earlier, so check the days 1 to 20 and 21 to 100 amounts in any plan you consider.

Medicare Advantage Spending Limit 2027: $9,850 Ceiling, Lower Real Limits

Federal rules cap what an Advantage plan can require you to pay for covered Part A and Part B services. For 2027 the in-network ceiling is $9,850 and the combined in and out-of-network ceiling for plans that allow out-of-network care is $14,800. Both increased 6.5 percent. These limits were set in April.

Most plans choose lower limits. In 2026, KFF found an enrollment-weighted average in-network limit of $5,421. HMOs averaged $4,636 and PPOs averaged $6,592. Plans are expected to raise their limits again for 2027, especially PPOs. The limit resets on January 1, so a surgery scheduled in the second week of January starts your count from zero.

Two details can surprise people. The limit does not include your monthly premium. It also does not cover prescription drugs, which have their own separate cap under Part D. Always look at the plan’s summary of benefits for the limit, the hospital copay per day and per stay, and whether prior authorization is required for the services you use.

Medigap Premiums 2027: Why the Safety Net Costs More

Medigap, also called Medicare Supplement insurance, helps pay Original Medicare’s deductibles, coinsurance and copays. More than 12 million people, about 43 percent of those in Original Medicare, have it. Another 13 percent have no supplemental coverage at all. KFF reported an average monthly Plan G premium of $164 in 2023, about $1,968 a year, with state averages ranging from about $140 in places like Washington, D.C., Hawaii and New Mexico to $236 in New York. The average has almost certainly risen since.

Rates are climbing faster than they used to. In Ohio, annual increases that once ran 3 to 5 percent now run 10 to 15 percent, according to the KFF Health News reporting. Telos Actuarial’s review of filings from six large insurers found Plan G increases in the first quarter of 2026 ranging from just over 12 percent to more than 26 percent. In Alaska, one insurer raised Plan G by nearly 12 percent, taking a sample 65-year-old woman’s premium from $172 to $192. A broker in Illinois described a 45 percent mid-year increase from one insurer. Industry commentary suggests more increases are on the way for 2027, though plan-specific rates vary by age, location and rating method.

The Part B deductible matters for Plan G buyers. Plan G pays nearly all costs after you meet the Part B deductible, so a higher deductible means you pay more before the plan starts to work. At the Trustees’ $292, the extra cost is $9 over 2026. If the higher private forecast of $310 holds, the extra cost is $27.

Medigap plans with a high deductible cost far less each month, but the deductible is currently just under $3,000 a year, and many people are not comfortable with that exposure. Weigh it against your savings, not your current health.

Medigap Enrollment Rules: Timing Can Decide Your Options

Timing matters more for Medigap than for any other part of Medicare. New enrollees have six months after enrolling in Part B to buy a policy at standard rates without health questions. After that, insurers in most states can use medical underwriting and can deny coverage or charge more.

Several exceptions help. People who leave Medicare Advantage for Original Medicare during their first year in an Advantage plan have a 12-month trial right to buy Medigap without health questions. If your Advantage plan leaves the market, you may qualify for a guaranteed purchase window. About 2.6 million people lost Advantage coverage at the end of last year when insurers exited markets, and about 440,000 of them moved to Medigap, according to Deft Research. At least 16 states have a birthday rule that lets you switch Medigap plans around your birthday without underwriting, and Connecticut, Massachusetts, Maine and New York require insurers to offer at least one policy to all applicants 65 and older. Ask your SHIP counselor which rule applies where you live.

Medicare 2027 Costs Compared: Four Health Scenarios

Numbers are easier to judge in context. The table below uses the Trustees’ 2027 projections and the assumptions listed under it. It excludes prescription drug costs, which are similar across options if you use the same drugs, and it shows the yearly total of premiums plus your share of medical bills.

Assumptions: Part B premium of $209.50 and deductible of $292. Medigap Plan G at $190 a month. Advantage premium of $12 a month, cost sharing of 15 percent of outpatient charges plus $350 per hospital stay, and a $5,500 spending limit. Original Medicare with no supplement pays the 20 percent Part B coinsurance and a $1,788 deductible per stay. Your plan’s numbers will differ.

Two lessons stand out. In a light year, going without a supplement or choosing an Advantage plan costs less, because Medigap premiums are a fixed price for protection you may not use. In a serious year, Original Medicare with no supplement is the riskiest choice, because it has no ceiling. The Advantage plan limits the damage but only if your providers are in network and your plan covers the services. Medigap Plan G costs the same every year no matter how much care you use, which is its value, but its rates can rise.

How to Apply for Medicare or Change Plans for 2027

If you are turning 65, your Initial Enrollment Period lasts seven months. It begins three months before the month you turn 65, includes your birthday month and ends three months after. Apply online through the Social Security Administration, call 1-800-772-1213 or visit a local office. If you already get Social Security benefits, you are usually enrolled in Parts A and B automatically.

If you already have Medicare and want to change coverage for 2027, work in this order:

1. Read your Annual Notice of Change. It should have arrived in September and lists next year’s premiums, deductibles and benefit changes.
2. Add your drugs, doses and pharmacy to your Medicare account so Medicare Plan Finder can estimate real costs.
3. Compare total yearly cost, not only premium. Add the premium, deductible, copays, drug costs and the plan’s spending limit.
4. Confirm that your doctors, hospital and pharmacy are in network, using the exact plan name.
5. Enroll through Plan Finder, call the plan or call 1-800-MEDICARE. Your last choice made before December 7 is the one that counts.

If you want to move from Advantage to Original Medicare and keep Medigap, apply for the Medigap policy first, then cancel Advantage, so that you are never uncovered. Free help is available from your State Health Insurance Assistance Program.

Medicare Enrollment Processing Time

Processing times vary and there is no single official guarantee, so treat the following as typical. Plan changes made by December 7 are designed to take effect on January 1, 2027. Plans usually send a confirmation and a new member card before the new year, and you should call if nothing arrives by mid-December. Applications handled by Social Security can take longer if proof of age or work history is needed, so apply early in your seven-month window. A new Medigap application is reviewed by the insurer, and if medical underwriting applies, it can take days or weeks. Keep your current coverage in force until you have written approval of the new policy.

Medicare Payment Schedule: How and When You Pay

• Part B premium: taken from your monthly Social Security or railroad retirement check. If you do not receive those benefits, Medicare bills you, either quarterly or through Easy Pay from a bank account.
• Medigap premium: paid directly to the insurer, by monthly, quarterly or annual bill depending on the company.
• Advantage premium: paid to the plan, or withheld from your Social Security payment if you choose.
• Income-related surcharges: Part B surcharges are deducted automatically, while Part D surcharges are billed directly by Medicare.
• The $90 payment: expected to arrive by direct deposit, with no application announced and no date published yet.
• New premiums start in January 2027, and the first Social Security check showing the new Part B amount arrives that month.

Conclusion

Medicare 2027 costs are less about one premium number and more about which risk you choose to carry. Original Medicare alone is cheapest in a quiet year and the most expensive in a bad one. Medigap smooths the bills but carries steep and often unpredictable rate increases. Medicare Advantage keeps premiums low and puts a ceiling on spending, at the price of networks and prior authorization. Before December 7, read your Annual Notice of Change, run the numbers for a light year and a serious year, confirm your doctors and decide with the worst case in mind. If you are eligible for the $90 payment, it will arrive automatically, and no caller can speed it up. We will keep this article updated as CMS confirms the final Part B premium and income brackets.
