This page collects the 2027 Medicare amounts that CMS and the IRS have officially published, and compares them with 2026. Medicare's costs are federal, so they're the same in Dayton, Akron, Youngstown, Lima or Portsmouth. For the full set of 2026 amounts, see Medicare costs in 2026.

Where things stand on November 13, 2026: CMS has published the 2027 Part D benefit amounts and base beneficiary premium, the Medicare Advantage out-of-pocket limits, the Medigap Plan K, Plan L and high-deductible amounts, and the Extra Help copays. CMS has not yet published the 2027 Part A and Part B premiums and deductibles or the 2027 IRMAA brackets; it usually does that in November. We don't estimate them. Extra Help and Medicare Premium Assistance Program income limits for 2027 usually follow in early 2027, after the new federal poverty guidelines. Check the CMS fact sheets page for the announcement.
What's changing from 2026 to 2027?
These are the 2027 amounts published so far, next to the 2026 amounts they replace.
| Amount | 2026 | 2027 | Change |
|---|---|---|---|
| Part D out-of-pocket cap | $2,100 | $2,400 | +$300 |
| Highest Part D deductible a plan can charge | $615 | $700 | +$85 |
| Part D national base beneficiary premium (monthly) | $38.99 | $41.33 | +$2.34 |
| Insulin, per month's supply of each covered insulin | $35 | $35 | No change |
| Medicare Advantage in-network out-of-pocket limit (highest allowed) | $9,250 | $9,850 | +$600 |
| Medicare Advantage PPO combined limit (highest allowed) | $13,900 | $14,800 | +$900 |
| Medigap high-deductible Plan G and Plan F deductible | $2,950 | $3,050 | +$100 |
| Medigap Plan K out-of-pocket limit | $8,000 | $8,360 | +$360 |
| Medigap Plan L out-of-pocket limit | $4,000 | $4,180 | +$180 |
| Part B standard premium, Part B deductible, Part A deductible | See the 2026 page | Not yet published by CMS | — |
| IRMAA brackets and amounts | See the 2026 page | Not yet published by CMS | — |
The Part B coinsurance (20% of the Medicare-approved amount for most services) and the Part B late penalty (10% of the standard premium for each full 12 months you delayed) are set by law and don't change in 2027.
How much will Part D drugs cost in 2027?
| Part D amount | 2027 |
|---|---|
| Yearly cap on your out-of-pocket costs for covered drugs | $2,400 |
| Highest yearly deductible a plan can charge | $700 |
| Most you pay for a month's supply of each covered insulin | $35 |
| National base beneficiary premium (used to figure the late penalty) | $41.33 a month |
The cap and the deductible both rise in 2027 because federal law ties them to growth in Part D drug spending. Once what you pay for covered drugs reaches $2,400, you pay nothing more for covered Part D drugs for the rest of 2027. Each plan sets its own premium and can have a lower deductible or none.
The Part D late enrollment penalty is 1% of the national base beneficiary premium for each full month you went without Part D or other creditable drug coverage, so the penalty rises when that premium rises. Ohio is its own Part D region (Region 14), and for 2027 CMS lists 9 standalone Part D plans in Ohio from 5 companies. Estimate how fast you'd reach the cap with the drug cap calculator (it uses 2026 amounts), and read more on Part D in Ohio.
Tip: Plans change their drug lists, pharmacy networks and costs each year, so read your plan's Annual Notice of Change and check your prescriptions before the Annual Enrollment Period ends on December 7, 2026.
What are the Medicare Advantage out-of-pocket limits for 2027?
| Medicare Advantage limit | 2027 maximum |
|---|---|
| In-network services (HMO and PPO) | $9,850 |
| In- and out-of-network services combined (PPO) | $14,800 |
These are the highest limits CMS allows for Part A and Part B services in 2027; each plan sets its own limit at or below them and shows it in its Summary of Benefits. The limit resets every January 1. Drug costs count toward the separate Part D cap, and you still pay the Part B premium with a Medicare Advantage plan. Original Medicare has no yearly out-of-pocket limit, which is one reason many people pair it with Medigap.
For 2027, CMS lists 119 Medicare Advantage plans open to everyone statewide in Ohio from 20 companies, plus 46 special needs plans, and every county still has regular Medicare Advantage plans. Some plans are ending, though: at least 38,178 Ohioans must choose new coverage. If your plan is ending, you can choose new coverage through February 28, 2027 (choose by December 31 to avoid a gap), and you may have a guaranteed right to buy a Medigap policy within 63 days after your plan coverage ends. See Ohio plans ending in 2027 and Medicare Advantage in Ohio.
Which Medigap amounts change in 2027?
Insurance companies set Medigap premiums, but CMS sets a few amounts for the standardized plans each year:
| Medigap amount | 2027 |
|---|---|
| High-deductible Plan G deductible (also high-deductible Plan F, for people eligible for Medicare before 2020) | $3,050 |
| Plan K yearly out-of-pocket limit | $8,360 |
| Plan L yearly out-of-pocket limit | $4,180 |
| Plan N copays | Up to $20 for some office visits, up to $50 for emergency room visits that don't lead to admission |
Thinking about changing Medigap plans for 2027? Ohio has no birthday rule or annual switching right. A bill has been proposed to add one; it is not law. Outside your Medigap open enrollment period or a guaranteed-issue situation, a new insurer can usually review your health. See Medigap in Ohio.
What will Extra Help copays be in 2027?
Extra Help (the Part D Low-Income Subsidy) lowers drug plan premiums, deductibles and copays. CMS has set the most people with Extra Help pay per prescription in 2027:
| Most you pay per prescription | Generic, 2026 | Generic, 2027 | Brand name, 2026 | Brand name, 2027 |
|---|---|---|---|---|
| Most people with Extra Help | $5.10 | $5.80 | $12.65 | $14.40 |
| People with full Ohio Medicaid and income at or below 100% of the poverty level | $1.60 | $1.65 | $4.90 | $5.00 |
People with full Medicaid who live in a nursing facility, or who get home and community-based services instead (in Ohio, for example, through PASSPORT or the MyCare Ohio Waiver), pay nothing for covered Part D drugs. The 2027 Extra Help income and resource limits aren't published yet; until then, the 2026 limits are the latest official amounts.
IRMAA in 2027: which income counts?
Higher-income people pay an income-related monthly adjustment amount (IRMAA) on top of the Part B premium and their Part D plan premium. Social Security generally uses your modified adjusted gross income (MAGI) from two years earlier, so 2027 IRMAA is based on your 2025 federal tax return. Your Ohio state income tax return plays no part. The brackets are cliffs: a single dollar over a threshold moves you into the whole higher amount. A one-time event in 2025, such as a large DROP payout taken as cash, a big Roth conversion or the sale of farmland or a business, counts.
CMS hasn't published the 2027 IRMAA brackets or amounts yet; they come with the Part B premium announcement. For comparison, in 2026 IRMAA started above $109,000 of MAGI for a single filer and $218,000 for a married couple filing jointly; the full 2026 table is on the 2026 costs page, and the IRMAA calculator uses the 2026 brackets until the 2027 ones are official.
Tip: If your income dropped after 2025 because you retired from a school district, a city or the state, cut back on work, lost a pension or your spouse died, you can ask Social Security to use a more recent year with Form SSA-44.
Part A and Part B in 2027: not published yet
The 2027 Part B standard premium and deductible, the Part A hospital deductible and coinsurance, and the Part A premium for people without enough Medicare-covered work all come from one CMS announcement, usually released in November, which takes effect January 1. As of November 13, 2026, CMS had not published it, and we don't estimate these amounts. If you get Social Security, your notice for 2027 will show the new Part B premium and your cost-of-living adjustment together. If you don't, Medicare's premium bill will show it.
Until then, the latest official amounts are for 2026: a standard Part B premium of $202.90 a month, a Part B deductible of $283 and a Part A deductible of $1,736 per benefit period. All 2026 Part A and Part B amounts are on Medicare costs in 2026.
Ohio public retirees: what to watch for 2027
Ohio's retirement systems set their own 2027 health care premiums, credits and HRA deposits, separately from Medicare. STRS Ohio's 2027 open enrollment runs November 1 to 24, 2026, and plans bought through the OPERS Medicare Connector or OP&F's marketplace follow Medicare's December 7 deadline. Whatever your system offers, you still pay the Part B premium (and any IRMAA) to Medicare. See Ohio public retirement systems and Medicare.
Still working at 65? HSA limits for 2027
If you're delaying Medicare because you have a high-deductible plan through current work, the IRS limits for 2027 are $4,500 for self-only coverage and $9,000 for family coverage, plus a $1,000 catch-up for people 55 and older. Once you're enrolled in any part of Medicare, you can't contribute to an HSA. Part A can start up to six months before the month you sign up (but not before you turn 65), so many people stop contributions six months before they enroll. See working past 65.
Where can Ohioans get help paying Medicare costs in 2027?
Medicare Premium Assistance Programs

Frequently asked questions
What is the Medicare Part B deductible for 2027?
CMS hasn't published it yet. The 2027 Part B premium and deductible come in one CMS announcement, usually in November, and take effect January 1. Until then, the latest official Part B deductible is the 2026 amount, $283.
What is the Medicare Part A hospital deductible for 2027?
CMS hasn't published it yet; it comes in the same fall announcement as the Part B premium. The latest official amount is the 2026 deductible of $1,736 for each benefit period. We add the 2027 amount once CMS releases it and don't estimate it.
What is the Part D out-of-pocket cap for 2027?
$2,400. Once your out-of-pocket costs for covered Part D drugs reach that amount in 2027, you pay nothing more for covered drugs for the rest of the year. The cap was $2,100 in 2026, and the most a plan can charge as a deductible rises from $615 to $700.
What income is used for IRMAA in 2027?
Social Security generally uses the modified adjusted gross income on your 2025 federal tax return. Your Ohio state return isn't used. If your income dropped after 2025 because you retired or had another life-changing event, you can ask Social Security to use a more recent year with Form SSA-44.
How high can a Medicare Advantage plan's out-of-pocket limit be in 2027?
Up to $9,850 for in-network Part A and Part B services, up from $9,250 in 2026. For PPO plans, the combined in-network and out-of-network limit can be up to $14,800. Each plan sets its own limit at or below these amounts.
My Ohio plan is ending in 2027. Does that change my costs?
Your new plan's premium, deductible and copays will be its own, so compare before you choose. You have until February 28, 2027 to pick new coverage, and choosing by December 31, 2026 avoids a gap. If you return to Original Medicare, you may have a guaranteed right to buy a Medigap policy within 63 days after your old plan's coverage ends.
