Medicare Part B: What You Need to Know to Save Money
Medicare Part B plays a major role in your healthcare coverage, but getting the most out of it requires knowing how it works. Whether you’re enrolling for the first time or already have it, making informed decisions can save you money while ensuring you stay covered. Here’s what you should know.
1. Medicare Part B Covers More Than Just Doctor Visits
Medicare Part B isn’t just about routine doctor visits—it covers a variety of medically necessary services and preventive care, including:
-
Outpatient Care: Doctor’s visits, specialist consultations, and some outpatient hospital services.
-
Preventive Services: Screenings, vaccinations, and wellness visits to help detect health issues early.
-
Durable Medical Equipment (DME): Items like wheelchairs, oxygen supplies, and diabetic testing equipment.
-
Mental Health Services: Counseling, therapy, and psychiatric evaluations when needed.
-
Home Health Care: Limited services, such as skilled nursing care or therapy prescribed by a doctor.
Knowing the full range of what Medicare Part B covers ensures you take advantage of the benefits you’re already paying for.
2. There’s a Standard Monthly Premium—But It Can Be Higher
For 2025, the standard Medicare Part B monthly premium is $185. However, some people pay more due to the Income-Related Monthly Adjustment Amount (IRMAA). If your modified adjusted gross income exceeds certain thresholds, you’ll face higher monthly costs.
IRMAA is based on your tax return from two years prior, meaning your 2023 income determines what you pay in 2025. Reviewing your income and tax situation can help you anticipate and manage these costs.
3. Late Enrollment Comes with Permanent Penalties
If you don’t sign up for Medicare Part B when you’re first eligible, you might have to pay a late enrollment penalty—for life. This penalty increases your monthly premium by 10% for each full 12-month period you were eligible but didn’t enroll.
To avoid this penalty, you must sign up during your Initial Enrollment Period (IEP), which lasts for seven months:
-
Three months before your 65th birthday
-
The month you turn 65
-
Three months after your birthday month
If you miss this window, you’ll have to wait for the General Enrollment Period (January 1 to March 31), with coverage starting July 1—and you may face late penalties.
4. There’s a Special Enrollment Period If You Have Employer Coverage
If you’re still working and covered by a group health plan through your employer (or your spouse’s), you may qualify for a Special Enrollment Period (SEP) to sign up for Part B without penalties. This period lasts eight months after your employment or coverage ends.
The key is ensuring your employer coverage meets Medicare’s creditable coverage standards. If it doesn’t, you might still face penalties for delaying enrollment.
5. Medicare Part B Has a Deductible and Cost-Sharing
In addition to premiums, you’ll pay an annual deductible of $257 in 2025 before Medicare starts covering services. After meeting the deductible, Medicare generally covers 80% of approved services, leaving you responsible for the remaining 20% with no out-of-pocket cap.
This means a serious illness or ongoing medical needs could lead to significant out-of-pocket expenses. Many beneficiaries explore supplemental coverage to help with these costs.
6. Preventive Services Are Free, but Other Services Have Costs
Medicare Part B fully covers certain preventive services at no cost to you, such as:
-
Annual Wellness Visits
-
Screenings for cancer, diabetes, and cardiovascular conditions
-
Vaccinations, including flu and COVID-19 shots
However, diagnostic tests, follow-up care, and treatments related to these screenings may involve out-of-pocket costs. Understanding what’s fully covered and what’s not helps you plan for medical expenses.
7. Understanding Medicare Coordination Can Save You Money
If you have other health coverage—like employer insurance, retiree benefits, or Medicaid—Medicare might not be your primary payer. Knowing which plan pays first can help you avoid unexpected bills.
The Medicare Secondary Payer (MSP) rules determine whether Medicare pays first or second. If you have employer coverage from a company with 20+ employees, Medicare usually pays after your work insurance. For smaller employers, Medicare is often primary, meaning it pays first, and your other coverage covers the rest.
Checking your coordination of benefits ensures you’re not overpaying or missing out on coverage that could reduce your costs.
What You Can Do to Make the Most of Medicare Part B
Maximizing your Medicare Part B benefits means staying informed and proactive. Here are a few steps you can take:
-
Review Your Coverage Annually: Medicare costs and coverage can change each year, so it’s smart to review your options annually.
-
Plan for Premium Increases: If your income changes, be prepared for IRMAA adjustments that could impact your Part B premium.
-
Use Preventive Services: These services are covered at no cost and can help detect issues before they become costly.
-
Understand Enrollment Periods: Missing deadlines can cost you in penalties and delayed coverage.
-
Coordinate with Other Coverage: If you have additional health insurance, understand how it works with Medicare to minimize out-of-pocket expenses.
