Medicare Part B: Your Medical Insurance Explained

Medicare Part B is the medical insurance component of Original Medicare. While Part A covers your room and board if you're admitted to a hospital, Part B covers the services and supplies that are medically necessary to treat your health condition. This includes doctor visits, outpatient care, preventive services, and durable medical equipment.

If you're building a healthcare strategy for your retirement, Part B is the engine that drives your day-to-day medical coverage. It's the part of Medicare you'll use most often, whether you're getting an annual wellness visit, seeing a specialist, or getting an X-ray.

What Does Medicare Part B Cover?

Part B coverage falls into two main categories:

• Medically necessary services: Services or supplies that are needed to diagnose or treat your medical condition and that meet accepted standards of medical practice.
• Preventive services: Health care to prevent illness (like the flu) or detect it at an early stage, when treatment is most likely to work best.

Specifically, Part B covers:

• Clinical research
• Ambulance services
• Durable medical equipment (DME)
• Mental health (inpatient, outpatient, and partial hospitalization)
• Getting a second opinion before surgery
• Limited outpatient prescription drugs

What Does Medicare Part B Cost?

Unlike Part A, which is premium-free for most people, everyone pays a premium for Part B. The standard Part B premium amount changes each year [as of 2024, varies by location and age]. If your modified adjusted gross income from two years ago is above a certain amount, you may pay an Income Related Monthly Adjustment Amount (IRMAA) on top of the standard premium.

In addition to the monthly premium, Part B has an annual deductible. Once you meet this deductible, you typically pay 20% of the Medicare-approved amount for most doctor services, outpatient therapy, and durable medical equipment. This 20% is your coinsurance.

Here's the reality check: That 20% coinsurance has no cap. If you face a $100,000 medical bill for outpatient cancer treatments or surgeries, your 20% share is $20,000. And there's no limit to how high that can go. That's why relying solely on Original Medicare is a massive financial risk. You've worked too hard to leave your life savings exposed to uncapped medical bills. Protect what you've earned.

This brings us to the core of your Medicare decision. You have two paths to protect yourself from that uncapped 20% liability.

The Two Paths of Medicare

Medsup vs MA is a rigged comparison; the real choice is Traditional Medicare (A+B) vs Medicare Advantage.

Path 1: Traditional Medicare + Medicare Supplement (Medigap)

In this path, Original Medicare (Part A and Part B) remains your primary insurance. You can see any doctor or visit any hospital in the country that accepts Medicare. To cover the gaps - like the Part B 20% coinsurance and deductibles - you purchase a Medicare Supplement plan. The supplement decision comes AFTER you choose Traditional Medicare - it's a component of the Traditional path, not an alternative to Advantage.

Path 2: Medicare Advantage (Part C)

In this path, you receive your Part A and Part B benefits through a private insurance company approved by Medicare. These plans often include prescription drug coverage and may offer extra benefits like dental or vision. However, they typically require you to use a network of doctors and hospitals, and you'll pay copays or coinsurance as you use services, up to an annual out-of-pocket maximum.

When to Enroll in Part B

Your Initial Enrollment Period for Part B begins three months before the month you turn 65, includes the month you turn 65, and ends three months after the month you turn 65. If you're still working and have creditable employer coverage, you may choose to delay Part B enrollment without penalty. However, if you miss your enrollment window without creditable coverage, you could face a permanent late enrollment penalty.

Understanding Part B is just the first step. The real work is deciding how to protect yourself from the costs it doesn't cover. We're on your side of the table. We'll walk you through every option, compare the numbers, and help you build a strategy that fits your life.
