Are You Eligible for Medicare? A New Jersey Guide

You are generally eligible for Medicare at 65 if you are a U.S. citizen, or a lawful permanent resident who has lived in the United States for at least five years in a row. Part A comes without a premium if you or your spouse worked about 10 years (40 quarters) in jobs that paid Medicare taxes. You can also qualify before 65 if you have received Social Security or Railroad Retirement Board disability benefits for 24 months, or if you have End-Stage Renal Disease or ALS. Living in New Jersey does not change federal eligibility, but it does shape the coverage you can add, especially if you are under 65, so this guide covers both.

The three ways to qualify

Eligibility is federal. Your Medicare card, your Part A and Part B, and your enrollment rights are the same in Camden County as anywhere else. What changes by state is the private coverage you can add on top: New Jersey's Medigap rules, which Medicare Advantage and Part D plans serve your county, and New Jersey programs such as PAAD and NJ FamilyCare.

• Age: you are 65 or older and a U.S. citizen, or a lawful permanent resident who has lived here for at least five continuous years.
• Disability: you are under 65 and have received Social Security Disability Insurance or certain Railroad Retirement Board disability benefits for 24 months. Medicare usually starts automatically in month 25.
• Specific conditions: End-Stage Renal Disease (permanent kidney failure that needs dialysis or a transplant), or ALS (Lou Gehrig's disease). With ALS, Medicare starts the month your disability benefits begin.

When Part A is premium-free

You can get Part A at 65 without a premium if any of these apply:

• You already receive retirement benefits from Social Security or the Railroad Retirement Board.
• You are eligible for those benefits but have not filed for them yet.
• You or your spouse had Medicare-covered government employment.

Part B has a premium for almost everyone

The 2026 standard Part B premium is $202.90 a month, and the annual deductible is $283 (CMS, 2026). Higher earners pay more through IRMAA, which in 2026 starts above $109,000 of modified adjusted gross income for a single filer or $218,000 for a married couple filing jointly, based on the 2024 tax return.

If you receive Social Security, Railroad Retirement or Civil Service retirement benefits, the Part B premium comes out of your check. If you do not, Medicare bills you, usually every three months.

You can delay Part B in some situations, most often when you or your spouse are still working and covered by an employer group plan. Delaying without that kind of coverage can lead to a lifetime penalty of 10 percent for each full 12 months you could have had Part B and did not.

Under 65 on Medicare in New Jersey

If you qualify for Medicare through disability, New Jersey has its own Medigap rule. According to the NAIC state chart (as of May 11, 2026), every company that sells Medicare Supplements in New Jersey must offer, at a minimum, Plan D to people under 65 who have Medicare because of a disability, at a rate no higher than its age 65 rate.

The New Jersey Division of Aging Services publishes those rates. For people ages 50 to 64, its September 2026 chart lists Plan D preferred rates from about $150 to $321 a month, depending on the company and whether you are a man or a woman. You get the preferred rate when you apply in your first 12 months of Part B or in a guaranteed issue situation; after that, a company may turn you down. For people under 50, the May 2026 sheet lists one Plan D, from Horizon Blue Cross Blue Shield of New Jersey, at $181.92 a month for women and $196.16 for men.

When you turn 65 you get a new six-month Medigap Open Enrollment Period, and you can then buy any Medigap plan from any company selling in New Jersey. Medicare Advantage plans and Special Needs Plans are open to you before 65 as well. If you have both Medicare and NJ FamilyCare (New Jersey Medicaid), a dual-eligible Special Needs Plan may fit: Camden County has 5 of them for 2027, according to the CY2027 CMS Landscape file.

What to have ready before you enroll

• Your Social Security number, and your Medicare card if it has already arrived.
• Details of any employer, retiree, COBRA, VA or TRICARE coverage you have now, and the date it ends.
• If you delayed Part B because you were working: form CMS-40B (Application for Enrollment in Part B) and form CMS-L564 (Request for Employment Information) completed by your employer.
• A list of your doctors and your prescriptions with doses, so you can compare plans the day you are eligible.

Moving to New Jersey with Medicare

If you move to New Jersey already on Medicare, your Part A and Part B come with you; you only update your address with Social Security. Your private coverage may not. Medicare Advantage and Part D plans are tied to service areas, so a move opens a Special Enrollment Period to choose a plan that serves your new county. Start looking before you move if you can, because the window is time-limited.

Most standardized Medigap policies keep working anywhere in the country, though the company may adjust the premium to New Jersey rates. If you have a Medicare SELECT policy with a network, moving out of its service area gives you a guaranteed issue right to buy a different policy.

Kidney failure (ESRD): when Medicare starts

End-Stage Renal Disease has its own timing, set out on Medicare.gov. You apply yourself; enrollment is not automatic. For people on dialysis, Medicare usually starts on the first day of the fourth month of dialysis, and the waiting period counts from your first treatment whether or not you have enrolled yet. If you take part in a Medicare-certified home dialysis training program during the first three months, coverage can begin as early as the first month of dialysis. For a kidney transplant, Medicare can begin the month you are admitted to a Medicare-certified hospital for the transplant, if the transplant happens that month or within the next two months.

If you also have an employer or union group health plan, Medicare.gov describes a 30-month coordination period: the group plan pays first and Medicare pays second for those 30 months, and then Medicare pays first. That timing affects when Part B is worth paying for, so ask the employer plan and Social Security before you decide.

A 2027 change: proof of citizenship or immigration status

The Medicare & You 2027 handbook lists a change on its What is new page: you must now meet certain citizenship, nationality or immigration status requirements to sign up for Medicare. If you are a lawful permanent resident, have your green card and the dates you have lived in the United States ready when you contact Social Security, and ask Social Security which documents it needs for your case.

What Jackie checks, and questions to ask

When someone asks Jackie whether they qualify, she starts with the facts Social Security will use, then moves to the choices that depend on them. These are the questions she works through, and they are the right ones to ask Social Security too:

• Do you have 40 quarters of work on your own record, or can you use the work record of a spouse, or in some cases a former spouse, for premium-free Part A? Your Social Security statement at ssa.gov shows your credits.
• Are you already collecting Social Security or Railroad Retirement benefits? If yes, you will be enrolled automatically; if not, when will you apply?
• Is there employer coverage from current work, through your own job or the job of your spouse, and how many employees does that employer have?
• Could you qualify for a Medicare Savings Program, PAAD or NJ FamilyCare? Medicare Savings Programs and PAAD take applications through NJSave (1-800-792-9745); NJ FamilyCare goes through your county welfare agency.
• If you are under 65 on disability or dialysis, which Medigap Plan D, Medicare Advantage or Special Needs Plan options fit, and what changes when you turn 65?

The bottom line

If you are 65, a citizen or long-term permanent resident, and you or your spouse worked about 10 years, you almost certainly qualify for premium-free Part A and can buy Part B. The real questions are timing and what you add on top. Check whether you will be enrolled automatically, decide whether you need Part B now, then compare the rest. If you are under 65, know New Jersey's Plan D rule and your 12-month window. Call or text Jackie at (856) 727-4221 if you want help confirming where you stand.
