Medicare shouldn't be so troublesome to understand, but here we are. You've probably heard about Parts A, B, C, and D, and maybe even those Supplement plans floating around. The alphabet soup of Medicare can leave anyone feeling confused.
Let's fix that.
Here's a straightforward breakdown of what each part actually does, what it costs in 2025/2026, and how to think about your options without pulling your hair out.
Part A: Hospital Insurance (The Foundation)
Part A covers your inpatient hospital stays. Think surgery, overnight hospital visits, skilled nursing facility care after a hospital stay, hospice care, and some home health services.
Here's the good news: Most people pay zero for Part A. If you or your spouse worked and paid Medicare taxes for at least 10 years, your premium is $0. Who doesn't love free?!
For 2026, here's what you need to know about costs:
- Premium: $0 for most people (about 99% of beneficiaries)
- Hospital deductible: $1,736 per benefit period
- Daily coinsurance: $434/day for days 61-90 of hospitalization
That deductible is per benefit period, not per year. A benefit period starts when you enter the hospital and ends when you've been out for 60 consecutive days. You could technically have multiple benefit periods in one year.
The daily coinsurance kicks in if you're hospitalized for longer stays. Days 1-60 are covered after your deductible. Days 61-90 cost you $434 per day. After that, it gets more expensive.
Part B: Medical Insurance (Your Doctor Visits)
Part B covers outpatient care. Doctor visits, preventive services, lab tests, medical equipment like wheelchairs or walkers, outpatient surgery, and most therapies fall under Part B.
The 2026 costs:
- Premium: $202.90/month (up from $185 in 2025)
- Annual deductible: $283
- Coinsurance: 20% of Medicare-approved costs after your deductible
That 20% coinsurance is crucial to understand. After you hit your deductible, you still pay 20% of whatever the service costs. There's no cap. If you have expensive medical needs, that 20% can add up quickly.
Parts A and B together are called "Original Medicare." It's solid basic coverage, but those gaps: especially that 20% coinsurance with no limit: leave many people looking for additional protection.
Part C: Medicare Advantage (The All-In-One Alternative)
Medicare Advantage plans are offered by private insurance companies approved by Medicare. These plans cover everything Parts A and B cover, plus they typically include prescription drug coverage (Part D) and extra benefits like dental, vision, and hearing.
Essentially, you're letting a private company manage your Medicare benefits instead of going directly through the government.
2026 average costs:
- Premium: $14/month (down from $16.40 in 2025)
- Cost sharing: Usually fixed copayments instead of percentage-based coinsurance
Sounds great, right? Lower premiums, extra benefits, predictable copays.
However, there are trade-offs. Medicare Advantage plans use networks. You'll need to see doctors within the plan's network, and you might need referrals to see specialists. If you travel frequently or spend time in multiple states, network restrictions can become frustrating.
Original Medicare lets you see any doctor in America who accepts Medicare. No networks. No referrals. You have complete freedom.

Part D: Prescription Drug Coverage
Part D covers your prescription medications. You need to enroll in a standalone Part D plan if you have Original Medicare, or it's typically included in Medicare Advantage plans.
2026 costs:
- Average premium: $34.50/month (down from $38.31 in 2025)
- Out-of-pocket limit: $2,100/year
Once you hit that $2,100 out-of-pocket limit, you pay nothing for covered prescriptions for the rest of the year. That's a huge relief if you take expensive medications.
Starting in 2025, there's also a monthly payment option. Instead of paying large amounts at the pharmacy when you need expensive drugs, you can spread those costs across the entire year. Much easier on your budget.
Medicare Supplement Plans: Filling the Gaps
If you choose Original Medicare (Parts A and B), you'll want to consider a Medicare Supplement plan: also called Medigap. These plans help pay the costs that Original Medicare doesn't cover, like that 20% coinsurance and deductibles.
Supplement plans are standardized. Plan G from Company A covers the exact same things as Plan G from Company B. The only differences are price and customer service.
Plan G vs. Plan N: The Two Most Popular Options
Let's break down the key differences between these two plans.
Plan G covers almost everything:
- Part A deductible
- Part A coinsurance and hospital costs
- Part B coinsurance (that 20%)
- Part B excess charges
- Skilled nursing facility coinsurance
- Foreign travel emergency coverage
The only thing Plan G doesn't cover is the Part B deductible ($283 in 2026). After you pay that once per year, Plan G covers the rest. No surprises. No big bills.
Plan N covers most things but with small copays:
- Part A deductible
- Part A coinsurance and hospital costs
- Part B coinsurance (with copays)
- Skilled nursing facility coinsurance
- Foreign travel emergency coverage
Plan N doesn't cover the Part B deductible or Part B excess charges. You'll also pay up to a $20 copay for doctor visits and up to a $50 copay for emergency room visits (waived if admitted).
So which one should you choose?
Plan G has higher monthly premiums but virtually no out-of-pocket costs when you need care. Plan N has lower premiums but those small copays add up if you visit the doctor frequently.
If you see doctors regularly or want absolute peace of mind with no surprise costs, Plan G makes sense. If you're healthy, don't visit doctors often, and want to save on premiums, Plan N could save you money.
My personal choice would be Plan G for most people. The predictability and comprehensive coverage are worth the extra premium, especially as you age and medical needs increase.

Putting It All Together
Here's a straightforward way to think about your Medicare coverage:
Original Medicare Route:
- Part A (hospital) – usually $0
- Part B (medical) – $202.90/month
- Part D (prescriptions) – around $34.50/month
- Supplement Plan G or N – varies by zip code and age
Medicare Advantage Route:
- Part C plan (includes A, B, and usually D) – around $14/month
- Possible copays for services
You can't have a Supplement plan and a Medicare Advantage plan at the same time. It's one or the other.
The Original Medicare route typically costs more per month but gives you complete freedom and predictable out-of-pocket costs. The Medicare Advantage route costs less monthly but comes with network restrictions and potentially higher costs when you actually use care.
What About Changes Each Year?
Medicare costs change annually. Part B premiums, deductibles, and coinsurance amounts are adjusted based on healthcare costs and other factors. You'll receive notices each fall about changes for the following year.
Part D plans and Medicare Advantage plans can change their coverage, networks, and costs every year. That's why there's an Annual Enrollment Period from October 15 to December 7, when you can switch plans if your current one no longer fits your needs.
Supplement plans are guaranteed renewable. Your coverage won't change as long as you pay your premium. Your premium will increase over time: that's normal as you age and healthcare costs rise: but your benefits stay the same.
You're Not Alone in This
Medicare has a lot of moving parts. You've got Parts A, B, C, and D, plus Supplement plans with their own letters. Then there are enrollment periods, penalties for late enrollment, and yearly changes to keep track of.
It's a lot. You aren't the only one who finds this overwhelming.
The key is understanding what each part actually covers, what you'll pay, and how the pieces fit together based on your health needs and budget. Take your time. Compare your options. Ask questions.
If you need help navigating your Medicare options, we're here for you. You deserve coverage that works for your situation without the stress and confusion.
Your golden years should be about living your life, not wrestling with insurance paperwork. Get the right coverage in place, and you can focus on what actually matters.
