Medicare Open Enrollment 2026: Key Updates You Need to Know

Hey, if you’re on Medicare or helping a parent or spouse navigate it, listen up — Open Enrollment for 2026 is right around the corner (October 15 through December 7), and this is the time when you can actually make changes that save you real money or fix gaps in your coverage. I’ve been helping seniors and their families sort through Medicare for the past nine years, and every year I see the same thing: people who skip reviewing their plan end up overpaying or missing better options. With nearly 69 million folks relying on Medicare, even small tweaks in the rules can affect a ton of people. The good news? Most things stay pretty steady in 2026, but there are a handful of updates on costs, plan choices, and prescription drugs that could make a real difference for you.






Before we get into the new stuff, let’s quickly recap the basics so everything makes sense. Original Medicare has two main parts: Part A covers hospital stays, skilled nursing, hospice, and some home health care. Part B takes care of doctor visits, outpatient stuff, ambulance rides, and preventive screenings. A lot of people stop there and add on extras because Original Medicare alone leaves some pretty big holes. That’s where Medicare Advantage (Part C) comes in — those are the bundled plans sold by private insurance companies that often include extra benefits. Then there’s Part D for prescription drugs. Most folks I talk to end up with some combination of these because the out-of-pocket costs on Original Medicare alone can add up fast.


One of the biggest shifts for 2026 is that there will be slightly fewer Medicare Advantage plans available across the country — roughly 5,600 plans, which is about the same as 2025 but down from earlier years. For some people that means fewer choices in certain areas, possibly tighter provider networks, or less flexibility if you travel a lot. I had a client in Florida last year who loved having tons of options, and she was a little disappointed when her area saw a drop. But here’s the flip side that a lot of people are happy about: with fewer plans, the ones that remain tend to be stronger and more competitive. And costs are actually trending down in some places. The average monthly premium for a Medicare Advantage plan that includes drug coverage is dropping from $16 to $14. Plus, the maximum out-of-pocket limit is coming down a bit — from $9,350 to $9,250. So even though the menu might be a little shorter, your wallet could feel a little lighter.


Now, the not-so-fun part: Part B premiums are going up. In 2025 they were about $257 a month (usually taken straight out of your Social Security check). For 2026 they’re expected to rise to around $288 per month. I know — nobody likes seeing that number climb. It’s the cost for basic medical services, so most people will feel this one. If you’re on a fixed income, that extra $31 a month adds up over the year.


On the prescription side, there are some mixed changes too. Stand-alone Part D plans are shrinking from 464 down to 360. But again, premiums are actually coming down a little — the average monthly premium for a stand-alone Part D plan should drop from $38 to $34, and for Medicare Advantage drug plans it’s going from $13 to $11. The catch? The annual deductible is rising from $590 to $615, and the out-of-pocket cap is going up slightly from $2,000 to $2,100. Still, that $2,100 cap is a lifesaver if you take expensive meds — once you hit it, the plan picks up the rest for the year. That protection is still really strong.


The government is also keeping up the work on negotiating lower drug prices in 2026. Certain medications for diabetes, heart disease, blood disorders, and autoimmune conditions are getting price cuts that could save billions overall. Insulin stays capped at $35 a month, and most vaccines continue to be covered at no extra cost. Another nice feature that’s sticking around is the ability to spread your prescription drug costs evenly across the year so you’re not hit with one giant bill in January.


Medicare is also making the website and tools a lot more user-friendly this year. There are new comparison features and even some AI-powered tools that let you check drug prices at different pharmacies in your area. I’ve already started using the updated planner with clients, and it makes shopping for plans way less confusing than it used to be.


There are a couple of policy tweaks too. Some Medicare Advantage plans will have new restrictions on certain extra benefits, and a few states are starting to use AI-assisted systems to approve or deny services. That could speed things up for some folks but might slow others down — we’ll have to see how it plays out in real life. On the bigger picture, even though recent laws didn’t directly slash Medicare, the rising national debt could trigger automatic budget cuts. Some estimates are talking about up to $45 billion possibly being trimmed in 2026 if nothing changes. It’s not locked in yet, but it’s something to keep an eye on because it could eventually affect services or coverage.


If there’s a government shutdown (and we all hope there isn’t), you might see delays in processing claims or slower answers to questions. Telehealth services that expanded during the pandemic are also winding down — without new laws, virtual visits could be limited mostly to rural areas. That’s a bummer for people who rely on remote care, especially if you live in a city or have mobility issues.


So what should you actually do during this enrollment period? Don’t just roll over and keep the same plan because it’s easier. Every year plans change their costs, networks, and covered drugs. Here’s my real-world checklist I give every client:


- Read your “Annual Notice of Changes” letter the day it arrives — it tells you exactly what’s different in your current plan.  

- Compare your plan against others using Medicare.gov or the new tools. Look at total costs (premiums + deductibles + copays), which doctors and hospitals are in-network, and whether your prescriptions are still covered.  

- Make sure your favorite doctors and specialists are still in the plan — networks can shift.  

- Check if your drugs are on the formulary and what tier they’re in (that affects how much you pay).  


I’ve had clients switch plans and save $800–$1,500 a year just by doing this one review. If your current plan is being dropped entirely in 2026, you’ll need to pick a new Medicare Advantage plan or go back to Original Medicare (and add a Part D if you need drug coverage). Just remember, going back to Original without extra coverage can leave you exposed on prescriptions and some other costs.


Bottom line: 2026 Medicare brings a mix of good news (lower average premiums in some areas, continued drug price negotiations) and some increases (Part B premiums, deductibles) plus fewer choices in certain spots. The smartest move you can make is to use this open enrollment window to look at everything with fresh eyes. Spend an hour or two comparing options now so you don’t spend the whole year regretting a decision you didn’t make.


If you’re feeling overwhelmed, reach out to a local State Health Insurance Assistance Program (SHIP) counselor — they’re free, unbiased, and know your area inside out. Or talk to a trusted Medicare advisor who isn’t trying to sell you one specific plan. You don’t have to figure this out alone.


Take a little time this fall to get it right. Being proactive during these seven weeks can mean lower costs, better coverage, and a lot more peace of mind all year long. You’ve worked hard for your retirement — make sure your healthcare coverage works just as hard for you in 2026.
