Medicare 101: What It Is and How to Prepare for Enrollment

By Marc C. Shaffer

As you approach age 65, one of the most important decisions you’ll make is how and when to enroll in Medicare.

For many, this is their first time navigating a government-run health insurance program, and the number of choices and acronyms can feel confusing and overwhelming.

But it doesn’t have to be.

At Searcy Financial® Services and Allos Investment Advisors, we believe that education is the first step to making confident, informed decisions about your financial future, including healthcare planning.  This guide will walk you through the basics of Medicare and provide a roadmap to help you prepare for enrollment.  We’ll also share how we can connect you with trusted resources for personalized Medicare support, so you’re not navigating it alone.

What Is Medicare?

Medicare is a federal health insurance program primarily for people aged 65 and older, though it also covers certain younger individuals with disabilities or specific conditions like End-Stage Renal Disease (ESRD).

It’s designed to help cover many healthcare expenses, but it doesn’t cover everything, so it’s important to understand the different parts and how they work together.

Medicare is divided into different parts:

  • Part A (Hospital Insurance) covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health care.
  • Part B (Medical Insurance) covers doctor visits, outpatient care, preventive services, and some home health care.
  • Part C (Medicare Advantage Plans) are all-in-one alternatives to Original Medicare, offered by private insurers, often including extra benefits like dental, vision, and prescription drugs.
  • Part D (Prescription Drug Coverage) helps cover the cost of prescription medications.

Most people don’t pay a premium for Part A if they or their spouse paid Medicare taxes while working.  However, Part B usually requires a monthly premium, and additional costs can come into play depending on your income and coverage choices.

Step 1: Understand Your Eligibility and Enrollment Window

You are eligible to enroll in Medicare starting three months before your 65th birthday, and you have a total of seven months to enroll (three months before, the month of, and three months after your birthday).

Missing this Initial Enrollment Period can result in delayed coverage and permanent late enrollment penalties.

If you’re already receiving Social Security benefits, you’ll be automatically enrolled in Parts A and B.  But if you’re not receiving Social Security yet, you’ll need to take the step to enroll on your own.  There are also Special Enrollment Periods and a General Enrollment Period each year for those who miss their initial window.

Knowing when and how to enroll can help you avoid costly mistakes.

Step 2: Evaluate Medicare Advantage vs. Medicare Supplement (Medigap)

One of the biggest decisions you’ll make is whether to choose a Medicare Advantage plan (Part C) or stick with Original Medicare (Parts A and B) and add a Medicare Supplement (Medigap) plan.

Medicare Advantage Plans:

  • Offered by private insurers and combine hospital, medical, and often drug coverage.
  • May include extras like dental, vision, hearing, and gym memberships.
  • Often have low or no additional premiums.
  • Use provider networks, which may limit you to specific doctors or hospitals.

Medicare Supplement (Medigap) Plans:

  • Work alongside Original Medicare to cover out-of-pocket costs like deductibles, copays, and coinsurance.
  • Offer broader access to providers—anyone who accepts Medicare.
  • Typically have higher monthly premiums.
  • Do not include prescription drug coverage, so you’ll need to enroll in a separate Part D plan.

The right choice depends on your budget, healthcare needs, travel habits, and doctor preferences. We’re happy to introduce you to experts who can walk through your unique situation and help you choose what’s best for you.

Step 3: Understand Medicare Part D (Prescription Drug Plans)

Even if you’re not currently taking many prescriptions, it’s usually wise to enroll in a Part D plan when you first become eligible. Waiting too long can lead to a permanent late enrollment penalty.  Part D plans are offered by private insurers and vary in cost, coverage, and pharmacy networks.  It’s important to compare plans based on the specific medications you take and where you prefer to fill prescriptions.

Choosing the right plan can significantly reduce your out-of-pocket drug costs.

Step 4: Consider Whether to Delay Enrollment

If you’re still working and have employer-sponsored health coverage, you may be able to delay enrolling in some parts of Medicare without penalty. For example:

  • You can often delay Part B without a penalty if you have credible health coverage through your employer.
  • Many people still choose to enroll in Part A, especially if it’s premium-free, because it can help reduce hospital expenses.

Before deciding to delay, it’s important to compare costs and coverage. Some workplace plans are less comprehensive or more expensive than Medicare options.  In some cases, you might qualify for premium reimbursements if you opt for Medicare over your employer plan.

Conducting a cost-benefit analysis with a professional can help ensure you’re making the financially optimal choice.

Step 5: Understand IRMAA—Income-Based Premium Adjustments

Higher-income Medicare beneficiaries may pay more for Part B and Part D due to an additional charge called the Income-Related Monthly Adjustment Amount (IRMAA). This surcharge is based on your Modified Adjusted Gross Income (MAGI) from two years prior.

Check out this flowchart: Will I Avoid IRMMA Surcharges On Medicare Part B & Part D?

Depending on your income, your Part B premiums in 2025 could range from $174.70 to $628.90 per month, and Part D adjustments could add $0 to $91.00 per month on top of your plan’s base premium.

Planning ahead, especially in the two years before you enroll, can help reduce your MAGI and potentially save you hundreds or even thousands of dollars per year in Medicare premiums.

We’re happy to walk through income reduction strategies and connect you with Medicare professionals to ensure you make the most financially sound decisions.

Step 6: Align Medicare with Your Financial Plan

Medicare isn’t just a health decision; it’s a financial decision. The choices you make around Medicare enrollment, plan selection, and timing can affect your budget, your taxes, and your overall retirement plan.  For example:

  • Starting Social Security automatically enrolls you in Medicare Parts A and B.
  • Delaying Social Security may delay automatic Medicare enrollment.
  • Healthcare costs are often one of the largest expenses in retirement, planning ahead is key.

We encourage our clients to take a proactive approach.  Together, we can help ensure that your Medicare decisions are aligned with your overall financial strategy.  From timing your Social Security benefits to planning Roth conversions or managing IRMAA impacts, your healthcare decisions should work in harmony with your retirement goals.
