If you’re turning 65 soon, Medicare enrollment is probably one of the most important financial and healthcare decisions you’ll make.

Many people assume Medicare is automatic. Others are unsure whether they should enroll in Part B, keep employer coverage, choose a Medicare Supplement plan, or enroll in a Medicare Advantage plan.

The good news is that a little preparation can help you avoid costly mistakes and enrollment penalties.

Use this Medicare checklist to stay on track as you approach your 65th birthday.

1. Know Your Medicare Enrollment Window

Your Initial Enrollment Period (IEP) lasts for seven months:

  • Three months before your birth month
  • Your birth month
  • Three months after your birth month

Missing this enrollment window could result in delayed coverage and penalties.

If you are already receiving Social Security benefits, Medicare enrollment may happen automatically.

If you are not receiving Social Security benefits, you will typically need to enroll yourself.

2. Decide Whether You Need Medicare Part A

Most individuals qualify for premium-free Medicare Part A.

Part A generally covers:

  • Hospital stays
  • Skilled nursing facility care
  • Hospice care
  • Certain home health services

Many people enroll in Medicare Part A at age 65 even if they continue working.

However, individuals contributing to a Health Savings Account (HSA) should understand how Medicare enrollment affects HSA eligibility.

3. Determine Whether You Should Enroll In Medicare Part B

Medicare Part B covers:

  • Doctor visits
  • Outpatient services
  • Preventive care
  • Laboratory testing
  • Durable medical equipment
  • Diagnostic services

If you are retiring or losing employer coverage, you will likely need Medicare Part B.

If you continue working and have qualifying employer group coverage, you may be able to delay Medicare Part B without penalty.

This is one of the most common areas where mistakes occur.

4. Review Your Employer Coverage

If you have health insurance through an employer, ask:

  • Is the coverage considered creditable?
  • How many employees does the employer have?
  • Do I need Medicare Part B?
  • Will Medicare become primary or secondary?

The answers can significantly affect your Medicare enrollment decisions.

5. Compare Medicare Supplement vs Medicare Advantage

One of the biggest decisions you’ll make is choosing between:

Medicare Supplement (Medigap)

Benefits often include:

  • Broad provider access
  • Predictable costs
  • Nationwide coverage
  • Fewer network restrictions

Medicare Advantage

Benefits may include:

  • Lower monthly premiums
  • Additional benefits
  • Provider networks
  • Copays and out-of-pocket exposure

Choosing the right option depends on your budget, healthcare needs, and personal preferences.

6. Review Medicare Supplement Plan Options

Many Medicare beneficiaries compare:

These are among the most popular Medicare Supplement plans available today.

Understanding the differences can help determine which option best fits your healthcare and financial goals.

7. Don’t Forget Medicare Part D

Even if you take few prescriptions today, Medicare Part D should not be ignored.

Delaying Part D enrollment without creditable drug coverage could result in a permanent late enrollment penalty.

Review:

  • Current medications
  • Preferred pharmacies
  • Part D plan options
  • Future prescription needs

before making a decision.

8. Understand Medicare IRMAA

Higher-income Medicare beneficiaries may pay additional premiums for:

This additional amount is called IRMAA (Income Related Monthly Adjustment Amount).

Understanding IRMAA can help avoid surprises after enrollment.

9. Gather Important Documents

Before enrolling, gather:

  • Social Security information
  • Employment information
  • Health insurance records
  • Prescription drug information
  • Medicare eligibility documentation

Having these documents available can make the enrollment process smoother.

10. Speak With An Experienced Medicare Broker

Medicare rules can be complicated.

An experienced independent Medicare broker can help explain:

Working with a knowledgeable professional can help you avoid costly mistakes.

Common Turning 65 Medicare Mistakes

Many people approaching Medicare age make mistakes such as:

  • Missing enrollment deadlines
  • Delaying Part B incorrectly
  • Ignoring Part D penalties
  • Choosing plans based solely on premium
  • Failing to understand employer coverage rules
  • Not reviewing Medicare Supplement options

A little planning can prevent many of these issues.
