Medicare Basics: What You Need to Know
If you’re approaching 65, you’ve probably realized that Medicare isn’t exactly simple.
There are multiple parts, different plan options, and important deadlines that can affect your coverage and costs for years to come. Most people feel unsure of where to start—and that’s completely normal.
This page will give you a clear, simple overview so you can understand how Medicare works before making any decisions.
Part A
Hospital Coverage
Covers inpatient hospital stays, skilled nursing care, hospice, and some home health services.
Most people don’t pay a premium for Part A if they’ve worked and paid into Medicare.
Part B
Medical Coverage
Covers doctor visits, outpatient care, preventive services, and medical equipment.
Part B does have a monthly premium and is an essential part of your coverage.
Part C
Medicare Advantage
Explore Original Medicare, Medicare Advantage, and Medigap plans to find coverage tailored to your health needs and budget.
Part D
Prescription Drug Coverage
Helps cover the cost of prescription medications.
Plans vary based on the medications you take, so it’s important to choose one that fits your needs.

Your Enrollment Timeline Matters
One of the most important parts of Medicare is when you enroll.
Your Initial Enrollment Period is a 7-month window:
- 3 months before you turn 65
- The month you turn 65
- 3 months after
Missing this window can lead to penalties or gaps in coverage, which is why planning ahead is so important.
Your Choices Go Beyond the Basics
Once you understand the parts of Medicare, the next step is choosing how you want your coverage set up.
Most people choose between:
Option 1: Original Medicare + Supplement + Part D
- Separate drug coverage
- More flexibility with doctors
- Predictable out-of-pocket costs
Option 2: Medicare Advantage Plan
- All-in-one coverage
- Often lower monthly premiums
- Network-based care
There’s no one-size-fits-all answer. The right choice depends on your health needs, prescriptions, doctors, and budget.
Common Mistakes to Avoid
Many people make decisions based on incomplete or incorrect information. Here are a few of the most common mistakes:
- Choosing a plan without checking if their doctor is included
- Not reviewing prescription coverage carefully
- Missing enrollment deadlines
- Assuming the same plan works for everyone
A little guidance upfront can prevent costly issues later.
