Here Is What Happened and Here Is What It Means
Medicare is changing again in 2027. Some of these changes were set in motion by the Inflation Reduction Act of 2022. Others are the result of annual cost adjustments that happen every year but rarely make headlines until the bill arrives. Seven changes deserve your attention. Five of them will cost you more money. Two of them will save you money, potentially a great deal of money if you take expensive medications.
This is not a political analysis. This is a dollar for dollar breakdown of what a typical 68 year old retiree on Original Medicare with a Part D plan and a Medigap supplement will pay in 2027 compared to 2026. Numbers first, context second, impact third.
Change 1. Part B Premium Increase. From $185 to an Estimated $195 Per Month.
The standard monthly premium for Medicare Part B, which covers doctor visits, outpatient care, and some medical equipment, is projected to increase from $185.00 in 2026 to approximately $195.00 in 2027. The exact number will be announced in the fall of 2026, but the Centers for Medicare and Medicaid Services has indicated that the increase will reflect rising healthcare costs and the expanded coverage of new treatments, particularly high cost medications administered in outpatient settings.
What this means for you. An additional $10 per month, or $120 per year. This is deducted automatically from your Social Security check. If you are enrolled in automatic payments, you will see the change reflected in your January 2027 deposit.
The context matters. Part B premiums have increased at an average annual rate of 5.4% over the past decade. The projected 2027 increase of 5.4% is consistent with that trend. This is not an aberration. It is the continuation of a long pattern.
Change 2. Part D Redesign Shifts Costs
The Part D prescription drug program is undergoing a structural redesign that began in 2024 and reaches its final phase in 2027. The redesign eliminates the old "donut hole" coverage gap entirely and replaces it with a new benefit structure that shifts more financial responsibility from enrollees to insurance plans and drug manufacturers.
In practical terms, Part D plans are absorbing more risk. That risk will be reflected in premiums. The average Part D premium is projected to increase from $34.70 in 2026 to between $38 and $42 per month in 2027, depending on the plan.
Some plans may also adjust their formularies, which means the list of drugs they cover and the tier on which they place each drug. A drug that was on Tier 2 (preferred brand) in 2026 may move to Tier 3 (non preferred brand) in 2027. When a drug moves up a tier, your copay increases even though the drug itself has not changed.
What this means for you. Check your plan's formulary in October 2026 when the Annual Notice of Change arrives. If your medications have moved tiers or if your plan's premium has increased significantly, use the Medicare Plan Finder at medicare.gov to compare alternatives during Open Enrollment from October 15 through December 7.
Change 3. IRMAA Thresholds Are Not Keeping Up With Inflation
IRMAA stands for Income Related Monthly Adjustment Amount. It is a surcharge that higher income Medicare enrollees pay on top of the standard Part B and Part D premiums. The thresholds that determine who pays IRMAA and how much they pay are adjusted annually, but the adjustments have not kept pace with inflation.
In 2026, the first IRMAA threshold for individuals is $106,000 in modified adjusted gross income. For married couples filing jointly, it is $212,000. These numbers sound high, but they catch more people than you might expect.
If you sold a house in 2025 and had a capital gain, you may have crossed the threshold. If you took a large distribution from a traditional IRA, you may have crossed it. If you did a Roth conversion, the converted amount counts as income for IRMAA purposes. One year of higher income triggers two years of higher premiums, because IRMAA is based on your tax return from two years prior.
In 2027, the thresholds are expected to rise by approximately 2 to 3 percent while actual inflation has been running higher. This means more middle income retirees will find themselves paying surcharges they did not pay before.
What this means for you. If your modified adjusted gross income was between $100,000 and $120,000 in 2025, check whether you will cross the IRMAA threshold. If you are planning a Roth conversion or a large IRA distribution, do the math first. The surcharge at the first bracket is an additional $70 per month per person for Part B, which is $840 per year for an individual or $1,680 per year for a couple.
Change 4. Medigap Rate Increases. 8 to 12 Percent on Average.
Medigap plans, also called Medicare Supplement plans, cover the gaps in Original Medicare. The most popular plan, Plan G, covers everything Original Medicare does not cover except the Part B deductible. Plan G premiums are projected to increase by 8 to 12 percent in 2027, depending on your state and your insurance carrier.
This is the result of rising healthcare utilization and medical cost trends. Insurance carriers set premiums based on claims data, and claims have been rising consistently since 2023.
For a 68 year old with Plan G, the average monthly premium is currently around $165 per month. An 8 to 12 percent increase would bring that to between $178 and $185 per month. That is an additional $156 to $240 per year.
What this means for you. Shop your Medigap plan annually. In most states, you can switch Medigap plans at any time, but you may be subject to medical underwriting after your initial open enrollment period. If you are healthy and your current plan's premium has increased substantially, contact an independent Medicare broker who represents multiple carriers. The coverage between Plan G from one carrier and Plan G from another carrier is identical. The only difference is the price.
Change 5. Prior Authorization Expansion
The Centers for Medicare and Medicaid Services is expanding prior authorization requirements for certain procedures and treatments in 2027. Prior authorization means your doctor must get approval from Medicare or your insurance plan before performing a procedure, ordering a test, or prescribing a treatment.
The expansion affects several categories. Advanced imaging such as MRI and CT scans will require prior authorization in more circumstances. Certain surgical procedures that were previously approved automatically will now require a review. Some durable medical equipment, including power wheelchairs and hospital beds, will have additional documentation requirements.
What this means for you. More paperwork. More waiting. More phone calls from your doctor's office saying they are still waiting for approval. In most cases, prior authorization adds 3 to 10 business days to the timeline for a procedure. For urgent matters, there are expedited review processes, but you should be aware that the burden of navigating these processes falls largely on your healthcare provider's staff.
The practical step you can take is simple. When your doctor recommends a procedure or test, ask whether it requires prior authorization. If it does, ask the office to submit the request immediately and ask for the reference number so you can follow up if needed.
The Cost Picture for 2027
Over the past seven years, the total annual cost of Original Medicare with a Medigap supplement has increased by approximately 47 percent. For context, Social Security cost of living adjustments over that same period have totaled approximately 31 percent. The gap between rising Medicare costs and rising income is the central financial challenge facing retirees on fixed incomes.
Now for the Good News. Change 6. The $2,000 Out of Pocket Cap on Prescriptions.
This is the single most significant improvement to Medicare in a generation. Starting in 2025 and fully in effect through 2027, no Medicare Part D enrollee will pay more than $2,000 out of pocket for prescription drugs in a calendar year. Once you hit $2,000 in total out of pocket drug costs, every additional prescription for the rest of the year is free.
Before this change, an enrollee taking a specialty drug could pay $10,000 or more out of pocket per year. The old Part D structure had a catastrophic coverage phase that still required 5% cost sharing, with no cap. For a drug that costs $15,000 per month, 5% is $750 per month. Per month. With no limit.
What this means for you. If you take expensive medications, this change could save you thousands of dollars per year. If you have been splitting pills, skipping doses, or choosing between medications and groceries, that era is over.
Medicare also offers a monthly payment plan called the Medicare Prescription Payment Plan that allows you to spread your out of pocket drug costs evenly across the year rather than paying large amounts in the first months. Contact your Part D plan or call 1 800 MEDICARE to enroll.
Change 7. Negotiated Drug Prices. 10 Drugs at Significantly Reduced Costs.
The Inflation Reduction Act gave Medicare the authority to negotiate prices directly with drug manufacturers for the first time. The first round of negotiations covered 10 drugs. The negotiated prices took effect in 2026 and continue in 2027. A second round of 15 additional drugs is being negotiated now, with prices taking effect in 2027 and 2028.
The 10 drugs with negotiated prices represent some of the most commonly prescribed and most expensive medications among Medicare enrollees.
| Eliquis | Blood clots and stroke prevention | $6,600 | $1,400 | $5,200 |
| Jardiance | Diabetes and heart failure | $5,800 | $1,300 | $4,500 |
| Xarelto | Blood clots | $5,200 | $1,100 | $4,100 |
| Januvia | Type 2 diabetes | $4,800 | $1,000 | $3,800 |
| Farxiga | Diabetes and kidney disease | $5,400 | $1,200 | $4,200 |
| Entresto | Heart failure | $6,000 | $1,400 | $4,600 |
| Enbrel | Rheumatoid arthritis | $31,200 | $7,000 | $24,200 |
| Imbruvica | Blood cancers | $85,000 | $18,000 | $67,000 |
| Stelara | Crohn's disease and psoriasis | $38,400 | $8,500 | $29,900 |
| Fiasp/NovoLog | Diabetes (insulin) | $4,200 | $900 | $3,300 |
These savings are not estimates or projections. They are the actual negotiated prices that Medicare enrollees are paying now and will continue paying through 2027.
What this means for you. If you take any of these 10 drugs, you are already paying less. If you are taking a different medication in the same class, talk to your doctor about whether switching to a negotiated drug is medically appropriate. For example, if you are taking a blood thinner other than Eliquis or Xarelto, the negotiated price on those two drugs may make them a significantly less expensive option.
The second round of negotiations covers 15 additional drugs that Medicare spends the most on. The list was announced in early 2026 and includes treatments for cancer, autoimmune conditions, blood disorders, and more. Negotiated prices for these 15 drugs will take effect between 2027 and 2028.
The Before and After for a Typical Retiree
To make this concrete, here is the annual Medicare cost comparison for a hypothetical 68 year old named Margaret. Margaret is on Original Medicare with Medigap Plan G and a standalone Part D plan. She takes Eliquis for atrial fibrillation and Jardiance for Type 2 diabetes. Her modified adjusted gross income is $65,000, which is below the IRMAA threshold.
| Part B premium (annual) | $2,220 | $2,340 | +$120 |
| Part D premium (annual) | $416 | $468 | +$52 |
| Medigap Plan G premium (annual) | $1,980 | $2,160 | +$180 |
| Eliquis out of pocket | $1,400 | $1,400 | $0 |
| Jardiance out of pocket | $1,300 | $1,300 | $0 |
| Other drug copays | $350 | $380 | +$30 |
| Part B deductible | $257 | $270 | +$13 |
| Total annual cost | $7,923 | $8,318 | +$395 |
Margaret's total Medicare cost increases by approximately $395 in 2027. That is $33 per month. Painful but manageable.
Now compare Margaret to a version of herself before the Inflation Reduction Act. Without drug price negotiations, her Eliquis would cost $6,600 per year and her Jardiance would cost $5,800 per year. Her total out of pocket drug costs alone would have been over $12,000 with no annual cap. Instead, her total drug costs are capped at $2,000. The negotiated prices and the out of pocket cap saved Margaret over $10,000 in a single year.
That is the full picture. Premiums are going up. Medigap costs are going up. Prior authorization is getting more burdensome. But for people who take expensive medications, the savings from negotiated drug prices and the out of pocket cap are transformational.
Five Steps to Take Before January 2027
First, review your Annual Notice of Change when it arrives in September or October. Every Part D plan and Medicare Advantage plan is required to send you this document. It tells you exactly what is changing in your plan for the coming year, including premium changes, formulary changes, and provider network changes. Read it.
Second, use the Medicare Plan Finder at medicare.gov during Open Enrollment from October 15 through December 7. Enter your medications and your preferred pharmacies. The tool will show you the total estimated annual cost for every plan available in your area. Do this even if you plan to keep your current plan. The five minutes it takes could save you hundreds of dollars.
Third, check your IRMAA exposure. Look at your 2025 tax return. If your modified adjusted gross income was near the $106,000 threshold for individuals or $212,000 for couples, you may be paying IRMAA surcharges in 2027. If you were over the threshold due to a one time event like a home sale, you can file form SSA 44 (Medicare Income Related Monthly Adjustment Amount Life Changing Event) to request a reduction.
Fourth, ask your doctor about the negotiated drug list. If you are taking a medication that has a less expensive negotiated alternative in the same drug class, a conversation with your doctor could result in a switch that saves you thousands per year.
Fifth, consider the Medicare Prescription Payment Plan. If your out of pocket drug costs in the first few months of the year are difficult to manage, this program spreads the cost evenly across all 12 months. It does not reduce your total cost, but it eliminates the financial shock of January and February when deductibles reset and drug costs hit hardest.
The Bottom Line
Medicare in 2027 is a mixed picture. Premiums are rising. Medigap is getting more expensive. Prior authorization adds friction to getting care. These are real costs that affect real household budgets.
But the structural improvements to the Part D program, particularly the $2,000 out of pocket cap and the negotiated drug prices, represent the most significant financial relief for Medicare enrollees since the program's inception in 1965. For the millions of Americans who take expensive medications, 2027 is substantially better than what came before.
The numbers do not lie. Medicare costs are going up. But for the first time in decades, the savings for those who need help most are going up faster.
That is what happened. That is what it means. Now you know what to do about it.
