New to Medicare

Getting started with Medicare can feel overwhelming—and you’re not alone. With so many parts and plans that all sound alike, it’s easy to get confused. Add in the stack of mail most people receive, and it can quickly become too much. We often have clients bring in a whole bag of mail and ask us to help sort through it. The good news is, we’re here to help—take a look below for a simple starting point to make sense of it all.

New to Medicare as Your Primary Insurance

Leaving employer coverage to enroll in Medicare as your primary insurance can be overwhelming. If you follow the correct steps, it is a painless process. The best way to get the most out of Medicare is to plan ahead of time. Our website has most of the information you need about Medicare planning.

First, you should know that you can only enroll in Original Medicare Parts A & B through the Social Security office. Enrollment for other parts and supplemental coverage is done through an insurance agent or agency. Also, if you already get Social Security, the government will enroll you in both Medicare parts. If not, you must enroll.

Here is a rundown of the initial steps:

Verify your Medicare eligibility.
Research Medicare costs to prepare for what you will pay.
Apply for Medicare at a Social Security office or online.
Get your red, white, and blue Medicare card. Is it showing both Part A and B? Part B is required if Medicare is your primary insurance.
Know your insurance options: Medicare Supplemental Insurance or Medicare Advantage.
Get someone on your side by working with an insurance agency like ours. Our advice is free, and we are always available.
Review your coverage annually to ensure you’re getting the best deal.

New to Medicare with Employer Coverage

The steps you take while working may be different. These days, many people work past the age of 65, which means choices such as: should you keep your employer’s coverage and enroll in Medicare as well? Is it cheaper to drop the employer coverage and go with Medicare as primary insurance with a supplement? The answers depend on several factors, including your employer’s size and your share of the premiums. See our Medicare and Employer Coverage page for details.

New to Medicare Frequently Asked Questions

When to enroll in Medicare depends on more than your age. Your current insurance, employment, Social Security benefits, and Health Savings Account can all affect the right next step. These answers explain the basics and when a closer review may be needed.

When does Medicare eligibility begin?

Most people first become eligible for Medicare at age 65, provided they meet Medicare’s eligibility requirements. Some qualify earlier because of a disability, ALS, or end-stage renal disease.

Eligibility and enrollment are different. Turning 65 does not mean everyone is automatically enrolled, and your coverage start date depends on your circumstances.

Do I have to enroll when I turn 65?

Not everyone needs to enroll in every part of Medicare at 65. Some people with group health coverage through their own or their spouse’s current employment can delay Part B without a late enrollment penalty.

Before delaying, confirm both whether your current plan will pay properly without Medicare and whether you qualify to enroll later without a penalty. COBRA, retiree coverage, and individual health insurance do not provide the same Part B enrollment protections as coverage based on current employment.

What if I have insurance through work?

For people eligible for Medicare because of age, an employer plan generally pays first when the employer has 20 or more employees. Medicare generally pays first when the employer has fewer than 20 employees. Certain multi-employer arrangements have different rules.

Being allowed to enroll in Part B later without a penalty does not necessarily mean your employer plan will cover the bills Medicare would normally pay. Ask the benefits administrator to confirm how the plancoordinates with Medicare before deciding to delay enrollment.

Getting started with enrollment

Will I be enrolled automatically or need to apply?

If you started receiving Social Security or Railroad Retirement Board benefits at least four months before turning 65, you are generally enrolled automatically in Parts A and B. Otherwise, you usually need to apply.

Most people apply through Social Security. You can apply for Medicare without starting Social Security retirement benefits. Railroad beneficiaries should contact the Railroad Retirement Board. Review your enrollment notice or Medicare card to confirm which coverage you have and when it begins.

When should I begin planning and sign up?

Start reviewing your options about three months before turning 65—or earlier if you have employer coverage or contribute to an HSA.

For most people first eligible at 65, the Initial Enrollment Period lasts seven months: the three months before your birthday month, your birthday month, and the following three months. When you enroll affects when coverage starts. Birthdays on the first of a month follow a different schedule.

If you qualify to delay Part B because of current-employment coverage, you may use a Special Enrollment Period later. Do not assume you need to wait for Medicare’s fall enrollment season to enroll in Parts A and B.

What if I contribute to a Health Savings Account?

Once your Medicare coverage begins, you are no longer eligible to contribute to an HSA for the months you are enrolled—even if you have only Part A. This also affects contributions made by your employer. You can continue using money already in your HSA for qualified expenses.

If you enroll after 65, premium-free Part A can be backdated up to six months, but not earlier than your first month of eligibility. Review your contribution cutoff before applying for Medicare or Social Security benefits.

Have questions about your timing?

We can help you review how Medicare fits with your current coverage and retirement plans. Have your insurance information, expected retirement date, and any HSA contribution details available when we talk.
