What’s the Difference Between Medicare and Medicaid in NJ?

In New Jersey, the difference between Medicare and Medicaid comes down to who the program is built for. Medicare is federal health insurance tied to age or disability, and your income does not matter. Medicaid, which the state runs as NJ FamilyCare, is coverage for residents with limited income, and age is only one factor. Some New Jerseyans qualify for both at once, and when that happens the two programs work together rather than overlap.

Who Each Program Is Built For

Medicare eligibility starts at 65 for most people. If you or your spouse paid Medicare taxes for at least 10 years (40 quarters of work), Part A hospital coverage comes with no monthly premium.¹ You can still enroll with fewer quarters, but you’ll pay a Part A premium between $311 and $565 per month in 2026.² You also need to be a U.S. citizen or a permanent resident with at least five continuous years in the country.

People under 65 reach Medicare two ways. Social Security Disability Insurance recipients become eligible after collecting benefits for 24 months, with ALS waiving the waiting period entirely.³ End-Stage Renal Disease is the other path, with eligibility usually starting the first day of the fourth month of dialysis.

NJ FamilyCare looks at your household income against the Federal Poverty Level. For adults 19 to 64, the ceiling is 138% of FPL, which is $1,836 per month for one person or $2,489 for a couple in 2026. Children under 19 are covered up to 355% of FPL ($9,763 per month for a family of four), and pregnant residents up to 205% of FPL ($5,638 per month for a family of four).⁴

Aged, blind, and disabled residents are measured against federal Supplemental Security Income standards, with resource limits of $2,000 for an individual and $3,000 for a couple.⁵ Bank accounts, stocks, and cash count; your primary home and one vehicle generally don’t. Because New Jersey is a “1634 state,” anyone approved for SSI is automatically enrolled in Medicaid. NJ FamilyCare has said eligibility rules for the aged, blind, and disabled categories will change starting in Fall 2026, so check current thresholds before applying.⁶

What Each Program Pays For

Original Medicare splits into two parts. Part A covers inpatient hospital stays, skilled nursing facility care, hospice, and home health care, with a $1,736 deductible per hospital admission in 2026.⁷ Part B covers outpatient care, doctor visits, lab work, durable medical equipment, and preventive screenings. The standard Part B premium is $202.90 per month in 2026 with a $283 annual deductible, after which you typically owe 20% of the Medicare-approved amount.² Prescription drugs are not included; you need a separate Part D plan, with out-of-pocket spending capped at $2,100 in 2026 and average premiums around $34.50 per month.

You can also take Medicare through a private Medicare Advantage (Part C) plan that bundles Parts A, B, and usually D, often with dental, vision, and hearing extras, in exchange for using the plan’s network.⁷

The gap worth flagging in Original Medicare: routine dental, vision exams, eyeglasses, and hearing aids are not covered. Medicare pays for dental or vision care only when it’s tied to a covered medical procedure such as jaw reconstruction, an organ transplant, diabetic retinopathy screening, or cataract surgery. Cleanings, dentures, and new glasses come out of your pocket unless you have supplemental coverage.

NJ FamilyCare covers a broader list of services: doctor visits, hospitalization, prescriptions, lab tests, X-rays, check-ups, preventive screenings, mental health and substance use treatment, dental care, eyeglasses, and personal care assistance.⁸ It also covers autism services and community doula services for pregnant enrollees.⁹ The dental and vision coverage matters most for people who have both programs, because it fills precisely what Medicare leaves out.

Long-Term Care: The Biggest Practical Difference

This is where the two programs part ways most sharply. Medicare pays for short-term skilled nursing after a hospital stay. It does not pay for long-term custodial care, meaning ongoing help with bathing, dressing, eating, and similar daily activities. Medicaid does.

New Jersey delivers that coverage through its Managed Long-Term Services and Supports program, known as MLTSS. The program covers nursing home stays, assisted living, and home and community-based services through NJ FamilyCare managed care organizations.¹⁰ Qualifying requires both financial eligibility and a clinical assessment showing you need a nursing-home level of care. Home and community-based services under MLTSS can include personal care assistants, meal delivery, home modifications, and non-emergency medical transportation.

With nursing home costs in the region often running $8,000 to $10,000 per month, MLTSS is the realistic payment source for most families facing a long-term care need. Two cautions apply before you move money around in anticipation of applying. First, the state reviews every financial transfer made during the 60 months before your application, and gifts or below-market sales during that window trigger a penalty period of Medicaid ineligibility. Second, federal law requires New Jersey to seek reimbursement from the estates of Medicaid recipients who received long-term care benefits after age 55, which usually means a claim against the family home after death.¹¹ Recovery is delayed when a spouse survives or a child under 21, blind, or permanently disabled survives. An elder law attorney is the right person to talk to before transferring assets or applying.

Having Both at Once

Roughly 12 million Americans are enrolled in both Medicare and Medicaid, and New Jersey has a large share of these “dual-eligible” residents. If you qualify for both, Medicaid pays your Medicare premiums, deductibles, and copays, and covers services Medicare excludes such as dental care and long-term care.

Even if your income is too high for full NJ FamilyCare, you may still qualify for a Medicare Savings Program that pays some or all of your Medicare costs. The 2026 thresholds for individuals:

Qualified Medicare Beneficiary (QMB) pays Part A and Part B premiums, deductibles, coinsurance, and copays, with an income limit of $1,350 per month and up to $9,950 in resources.¹²
Specified Low-Income Medicare Beneficiary (SLMB) pays Part B premiums, with an income limit of $1,616 per month and up to $9,950 in resources.¹²
Qualifying Individual (QI) also pays Part B premiums, with an income limit of $1,816 per month and up to $9,950 in resources. You reapply every year and funding is first-come, first-served.¹²

Couples get higher limits across all three. QMB is the most valuable because it eliminates nearly all Medicare out-of-pocket costs. Apply through NJ FamilyCare; the state administers these programs even though they offset federal Medicare charges.

Costs and Penalties Worth Knowing

Medicare has an enrollment window with a real cost for missing it. Your Initial Enrollment Period runs seven months: the three months before your 65th birthday month, that month, and the three months after. Miss it without qualifying for a Special Enrollment Period (which generally requires having had employer coverage), and your Part B premium increases 10% for every full 12-month period you were eligible but didn’t sign up. That penalty is permanent. Two years late means 20% extra on the 2026 standard premium of $202.90, which is $40.58 more every month for life.¹³

NJ FamilyCare has no comparable penalty and no limited enrollment season. You apply when your circumstances qualify you, year-round.

How to Apply

Medicare

If you’re already receiving Social Security benefits at 65, you’re enrolled in Parts A and B automatically. Otherwise, you sign up through the Social Security Administration at ssa.gov or at your local office.¹⁴

NJ FamilyCare

Apply online through the state’s portal or by mailing a printed application.⁶ You’ll need Social Security numbers for everyone in the household, proof of New Jersey residency (utility bill or lease), proof of citizenship or immigration status, and income documentation such as recent pay stubs or tax returns. Federal rules require the state to decide non-disability applications within 45 days and disability-based applications within 90 days.¹⁵ A denial notice will explain the reason and the appeal process.
