As a Medicare agent here in Wisconsin, I’ve had the privilege of helping countless people navigate their Medicare options. One thing I’ve noticed? Medicare Part B is often one of the most misunderstood parts of the process. It’s essential, yet the details can feel overwhelming at first.
That’s where I come in! My goal is to make Part B easy to understand so you can feel confident about your healthcare decisions. Whether you’re approaching 65, still working, or helping a loved one figure it all out, this post will break down what Medicare Part B covers, what it costs, and why it’s such an important part of your healthcare coverage.
Let’s dive into everything you need to know about Part B—and a few tips to help you avoid common mistakes.
What Is Medicare Part B?
Medicare Part B is one half of Original Medicare, alongside Part A. While Part A focuses on inpatient hospital care, Part B covers the medical services you use on a regular basis. This includes:
- Doctor visits (primary care and specialists)
- Outpatient care, like physical therapy or diagnostic tests
- Preventive services (things like flu shots, cancer screenings, and check-ups)
- Durable medical equipment, such as wheelchairs, walkers, and oxygen tanks
Think of it as your everyday healthcare coverage—the kind that helps you stay on top of your health rather than just treating you when something goes wrong.
Why Medicare Part B Matters
If you’re wondering whether you really need Part B, let me explain why it’s so important.
1. It’s Comprehensive Coverage
Without Part B, you’d be paying out of pocket for doctor visits, outpatient procedures, and preventive care. Even if you’re in good health now, having access to these services can save you thousands of dollars over time.
2. It Covers Preventive Care
Prevention is key! Medicare Part B covers many screenings and check-ups that catch potential health issues early—before they turn into major (and expensive) problems.
3. It Helps Manage Unexpected Costs
Health surprises happen. Whether it’s a sudden injury or an unexpected diagnosis, Part B ensures you won’t be left footing the entire bill. For example, without Part B, something as simple as an outpatient surgery could cost you thousands.
What Does Medicare Part B Cost?
Medicare Part B isn’t free, but the costs are manageable—and understanding them upfront can help you plan. Here’s what you’ll pay:
Monthly Premium
For most people in 2025, the standard Part B premium is $185 per month. However, if you earn more than $106,000 as an individual (or $212,000 as a couple), you’ll pay a higher premium due to IRMAA (Income-Related Monthly Adjustment Amount).
Annual Deductible
The annual deductible for 2025 is $257. After you’ve met this deductible, Medicare pays 80% of the cost for covered services, leaving you responsible for the remaining 20%.
Coinsurance
After the deductible, you’ll pay 20% of the Medicare-approved amount for most services. For example, if a doctor’s visit costs $100, you’ll pay $20, and Medicare will cover the rest.
Common Misconceptions About Part B
Let’s clear up a few myths that often cause confusion:
1. “I’m Healthy, So I Don’t Need Part B Yet”
Even if you’re in perfect health, skipping Part B when you’re first eligible could cost you down the line. Medicare charges a late enrollment penalty if you don’t sign up when you’re eligible, and that penalty sticks with you for life.
2. “I Have Other Insurance, So I’m Covered”
If you’re still working and have employer-sponsored health insurance, you might be able to delay Part B. But not all insurance counts as “creditable coverage.” It’s crucial to confirm this with your HR department or a Medicare agent (like me!) to avoid penalties later.
3. “Medicare Works Like Private Insurance”
Not quite. Medicare Part B doesn’t have a cap on out-of-pocket costs like some private insurance plans. This is why many people pair Part B with supplemental coverage, like Medigap, to fill the gaps.
How to Enroll in Medicare Part B
Signing up for Medicare Part B is straightforward, but there are a few important deadlines to keep in mind:
Initial Enrollment Period (IEP)
This is your first chance to enroll. It begins three months before your 65th birthday, includes your birthday month, and extends three months after.
General Enrollment Period (GEP)
If you miss your IEP, you can enroll during the General Enrollment Period from January 1 to March 31 each year. Coverage starts in July, but late penalties may apply.
Special Enrollment Period (SEP)
If you’re covered under employer health insurance when you turn 65, you can delay Part B without penalty. When that coverage ends, you’ll have an eight-month Special Enrollment Period to sign up.
Tips to Avoid Costly Medicare Part B Mistakes
Navigating Medicare can feel overwhelming, but here are some pro tips to help you avoid common pitfalls:
Sign Up On Time
Avoid the late enrollment penalty by signing up during your Initial Enrollment Period.Understand Your Coverage Needs
Part B works well with Medigap or Medicare Advantage plans. When deciding how to structure your coverage, consider your health needs and budget.Check Your Other Insurance
Confirm that your insurance is considered creditable under Medicare rules if you’re delaying Part B due to employer coverage.Review Your Coverage Annually
Even if you’re happy with your current plan, it’s a good idea to review your Medicare coverage each year during the Annual Enrollment Period (October 15 – December 7).
