Turning 65 in New Jersey: Your Medicare Checklist

Start about six months before the month you turn 65. Your Initial Enrollment Period is seven months long: the three months before your birthday month, the birthday month itself, and the three months after. Sign up in the first three months and Medicare starts on the first day of your birthday month. Inside that window you decide whether you need Part B now, choose between Original Medicare with a Medicare Supplement and a Part D plan or a Medicare Advantage plan, and line up drug coverage. New Jersey has no yearly Medigap switching window, so the supplement decision at 65 deserves real care. This checklist puts every step in order.

Six months before your birthday month

• Confirm your dates. If your birthday falls on the first of the month, Medicare treats you as turning 65 in the month before, so every date in this checklist moves a month earlier.
• Find out whether you will be enrolled automatically. If you already collect Social Security or Railroad Retirement benefits, your Medicare card arrives about three months before your birthday month. If not, you sign up through Social Security.
• If you or your spouse are still working, ask HR two questions: how many employees the company has, and whether the group plan pays first or second once you have Medicare. Those answers decide whether you need Part B right away.
• If you put money in a Health Savings Account, plan when to stop. Contributions must end once Medicare starts, and Part A can be backdated up to six months if you enroll after 65.
• Write down every doctor, specialist and hospital you want to keep, and every prescription with its strength and how often you take it. You will use this list in every comparison.
• Check your Social Security statement at ssa.gov to confirm you have 40 work credits (about 10 years) for premium-free Part A.

Three months before: your window opens

• Sign up for Part A and Part B if you need them, so coverage starts on the first day of your birthday month.
• Compare the two paths: Original Medicare with a Medicare Supplement and a Part D plan, or a Medicare Advantage plan that usually includes drug coverage.
• If you lean toward a supplement, plan to apply now. Your six-month Medigap Open Enrollment Period starts the month you are 65 and enrolled in Part B. During it, a company cannot turn you down or charge more because of your health.
• Check that your doctors work with the plans you are considering, and run your prescriptions through each plan's 2027 drug list.
• If you would like both paths laid out side by side, book a no-cost consultation with Jackie by phone, Zoom or in person.

Your birthday month and the three months after

• If you sign up in your birthday month or later, coverage starts the first of the month after you sign up. That can leave a gap after employer or individual coverage ends, so do not wait if you can avoid it.
• Make sure drug coverage starts when Medicare does. Going 63 days or more in a row without Part D or other creditable drug coverage after your Initial Enrollment Period ends can mean a penalty for as long as you have Part D.
• If you buy your own health plan through the marketplace, end it so it stops the day Medicare starts. Premium tax credits generally stop once you are eligible for premium-free Part A.
• Keep your red, white and blue Medicare card somewhere safe, even if you join a Medicare Advantage plan and use the plan card for care.
• When your plan cards arrive, check the names, start dates and member numbers, and show them at your next doctor and pharmacy visit so the offices update your records before the first bill.
• Set a reminder for late September each year, when your plan mails its Annual Notice of Change, so you can review before the Annual Enrollment Period opens on October 15.

The deadlines that carry penalties

Missing a Medicare deadline usually costs money every month for years. These are the three to know, using 2026 figures from CMS and Medicare.gov.

Why the Medigap decision at 65 matters in New Jersey

Some states give people a yearly birthday window to switch Medicare Supplement policies without health questions. New Jersey does not. The NAIC state chart (as of May 11, 2026) lists no birthday rule for New Jersey, so outside your six-month Medigap Open Enrollment Period and the federal guaranteed issue situations, a company can ask health questions and turn you down or charge more.

That does not mean a supplement is right for everyone. It means the choice is hard to reverse, so make it on purpose. If a Medicare Advantage plan appeals to you, ask about the federal trial right: if you join a Medicare Advantage plan when you are first eligible at 65 and leave within the first 12 months, you can buy a Medigap policy without health questions.

What is available in South Jersey for 2027

If you turn 65 between now and the end of 2026, you are shopping for plans that start in 2027. According to the CY2027 CMS Landscape file, Camden County has 41 Medicare Advantage plans from 10 organizations, not counting Special Needs Plans, and 34 of them include drug coverage. Burlington and Gloucester counties each have 39. New Jersey has 11 standalone Part D plans for 2027. The number that matters is not how many plans exist, though. It is how each plan treats your doctors and your prescriptions.

Questions Jackie asks at the first meeting

Jackie's approach is simple: ask questions, listen to your answers, and only then recommend the type of coverage that fits. These are the questions that settle most of the decision, whether you sit down with her or work through Medicare.gov on your own:

• Which doctors, specialists and hospitals do you want to keep, and do they accept Original Medicare, a particular plan network, or both?
• What prescriptions do you take, at what dose, and which pharmacy do you use?
• Do you travel, or spend part of the year outside New Jersey, for example in Florida?
• How much could you comfortably pay in a hard health year, and would you rather pay more each month to avoid that?
• Will you have employer, retiree, VA or TRICARE coverage alongside Medicare?
• Is your income likely to put you in an IRMAA bracket, or has it dropped because you retired?
• Do you want dental, vision or hearing coverage, and is it worth more inside a plan or as a separate policy?

Forms and official help

Social Security handles enrollment in Parts A and B, online at ssa.gov, by phone at 1-800-772-1213 or in person. If you are enrolling in Part B outside your first window because you had employer coverage, you need form CMS-40B and form CMS-L564 completed by your employer. If a life change such as retirement lowered your income, form SSA-44 asks Social Security to reconsider an IRMAA surcharge. 1-800-MEDICARE (1-800-633-4227, TTY 1-877-486-2048) answers general questions 24 hours a day, and the Medicare & You handbook covers the basics in one place.

A worked timeline for one hypothetical couple

This is an illustration with made-up birthdays, not a real client. Pat was born August 14, 1962 and turns 65 on August 14, 2027. Pat is not collecting Social Security yet, so nothing happens automatically. Chris, Pat's spouse, was born March 1, 1963. Both are on Pat's employer plan, which ends when Pat retires on July 31, 2027. Here is how the federal rules on Medicare.gov line up for them.

What Jackie checks for you before your birthday month

When someone calls Jackie about turning 65, this is the process, in this order. You can follow the same list on your own.

• Your exact dates: your Initial Enrollment Period and your Medigap window, worked out from your birth date, including the birthday on the 1st rule, and written down for you.
• Your other coverage: whether your employer, or the employer of your spouse, has 20 or more employees, whether the drug coverage is creditable, and whether you contribute to an HSA.
• Your doctors: each one looked up in the 2027 directories of the plans you are considering in your county, with a note on whether they accept Original Medicare.
• Your prescriptions: each drug priced, at its dose, at your pharmacy, for all twelve months in each plan, against the 2027 Part D limits ($700 maximum deductible, $2,400 cap).
• Both paths in dollars: Original Medicare with a supplement and a Part D plan, and Medicare Advantage, priced for your ZIP code and set side by side.
• The paperwork: Social Security sign up, form CMS-40B and CMS-L564 if you delayed Part B, and SSA-44 if retirement lowered your income.

The bottom line

Mark three dates: six months before your birthday month to gather your doctors, prescriptions and employer details, three months before to enroll and choose, and the last day of your Initial Enrollment Period as the final safe day for Part B and Part D. In New Jersey, treat the Medigap decision at 65 as the one that is hardest to change. If you would like a second set of eyes on your timeline, call or text Jackie at (856) 727-4221 and she will walk through it with you.
