Medicare 101: What You Need to Know Before You Enroll

August 17, 2026

Choosing Medicare is one of the most important retirement decisions you'll make. Understanding your options before you enroll can help you avoid costly mistakes and choose coverage that fits your healthcare needs.

Turning 65 is an exciting milestone, but it also brings important decisions about your healthcare coverage. Between Medicare Parts A, B, C, and D, enrollment deadlines, Medigap policies, and Medicare Advantage plans, it's no surprise that many people feel overwhelmed.

The good news? With the right information, Medicare becomes much easier to understand.

In this educational webinar, Joshua O'Brien of O'Brien Benefits Group, hosted by Jim Hendricks of Hendricks Wealth & Estate Management, explains the fundamentals of Medicare, common enrollment mistakes, and the choices you'll need to make as you approach retirement.


What Is Medicare?

Medicare is the federal health insurance program primarily available to individuals age 65 and older, although certain younger individuals with qualifying disabilities may also be eligible.

Understanding the different parts of Medicare is the first step toward making an informed decision about your healthcare coverage.


Understanding the Four Parts of Medicare

One of the biggest sources of confusion is that Medicare isn't a single insurance plan—it's made up of several parts, each serving a different purpose.

Medicare Part A

Part A generally helps cover:

  • Hospital stays
  • Skilled nursing facility care (under qualifying circumstances)
  • Hospice care
  • Some home health services

Many people qualify for premium-free Part A based on their work history.


Medicare Part B

Part B generally covers:

  • Doctor visits
  • Outpatient medical services
  • Preventive care
  • Laboratory work
  • Durable medical equipment

Unlike Part A, Part B typically requires a monthly premium.

Understanding when and how to enroll is important because delaying enrollment without qualifying coverage may result in penalties.


Medicare Part C (Medicare Advantage)

Medicare Advantage plans are offered by private insurance companies approved by Medicare.

These plans generally combine Parts A and B and often include additional benefits that may vary by plan.

Coverage, provider networks, and out-of-pocket costs differ among plans, making it important to compare options carefully.


Medicare Part D

Part D helps cover prescription medications.

Since every plan has its own list of covered medications (called a formulary), reviewing your prescriptions before selecting a plan can help ensure your medications are covered appropriately.


Medicare Supplement vs. Medicare Advantage: What's the Difference?

One of the most common questions retirees ask is whether they should choose a Medicare Supplement (Medigap) policy or a Medicare Advantage plan.

While both options work alongside Medicare, they function differently.

A Medicare Supplement policy is designed to help pay certain out-of-pocket costs associated with Original Medicare, while Medicare Advantage plans provide an alternative way to receive Medicare benefits through private insurers.

The right choice depends on factors such as:

  • Your healthcare needs
  • Preferred doctors and hospitals
  • Prescription medications
  • Travel habits
  • Budget
  • Overall retirement plan

Rather than focusing on which option is "better," it's more helpful to determine which one best aligns with your individual circumstances.


Why Enrollment Timing Matters

Missing important Medicare enrollment deadlines can result in delayed coverage or, in some situations, lifetime premium penalties.

The webinar explains:

  • Initial Enrollment Periods
  • Special Enrollment Periods
  • Annual Open Enrollment
  • Situations involving employer-sponsored health insurance

Planning ahead can help make your transition to Medicare much smoother.


Medicare Is Part of Your Retirement Plan

Healthcare decisions shouldn't be made in isolation.

Your Medicare choices can affect:

  • Retirement cash flow
  • Healthcare budgeting
  • Tax planning
  • Health Savings Accounts (HSAs)
  • Long-term retirement planning

Coordinating healthcare decisions with your overall financial plan can help you better understand how Medicare fits into your retirement income strategy.


Common Medicare Mistakes to Avoid

The webinar highlights several mistakes retirees commonly make, including:

  • Waiting too long to enroll
  • Assuming Medicare covers every healthcare expense
  • Choosing a plan without reviewing prescription drug coverage
  • Failing to compare Medicare Supplement and Medicare Advantage options
  • Not reviewing coverage as healthcare needs change

Taking time to understand your options before enrolling can help you make a more informed decision.
