New Jersey Medicare Plans and Coverage: A 2026 Guide

If you are turning 65 in New Jersey, you face one main decision: keep Original Medicare with a Medigap supplement, or take a Medicare Advantage plan. Original Medicare (Parts A and B) pairs with a standalone Part D drug plan; Medicare Advantage bundles it all through a private insurer's network. Medicare itself is federal, so the parts, the 2026 costs, and the enrollment rules are the same everywhere. What New Jersey changes is the help around that decision and the supplement market you buy into.

Two things set the state apart. New Jersey protects people who qualify for Medicare under 65 by disability, guaranteeing them a Medigap policy with no age surcharge, and it offers free, unbiased counseling through the State Health Insurance Assistance Program (SHIP). The most useful number to save first: New Jersey SHIP at 1-800-792-8820.

Original Medicare in New Jersey: Parts A and B

Original Medicare is the federal program: Part A covers hospital care and Part B covers doctors and outpatient care. Most people pay no Part A premium because they earned it through at least 10 years of Medicare-covered work. In 2026, the standard Part B premium is $202.90 per month, the Part B annual deductible is $283, and after the deductible you pay 20% of the Medicare-approved amount for most Part B services. The Part A hospital deductible is $1,736 per benefit period.1 These figures are set federally and apply identically in New Jersey.

Original Medicare has no annual cap on what you can spend out of pocket, which is why most people add either a Medigap supplement or choose a Medicare Advantage plan. Here is how the two paths compare.

New Jersey Medicare Advantage Plans (Part C)

Medicare Advantage plans are offered by private insurers and bundle Parts A, B, and usually D, often with extras like dental or vision, in exchange for using the plan's provider network. Every plan must cover everything Original Medicare covers except hospice, and every plan caps your annual in-network out-of-pocket spending, federally limited to $9,250 for Part A and B services in 2026, with many plans setting it lower.5 New Jersey has a competitive Advantage market, especially in the dense northern counties. The trade-off is the same everywhere: lower or zero premiums and bundled benefits, against network restrictions and prior authorization. Check that your doctors and preferred hospitals are in a plan's network before enrolling, and see the "Medigap in New Jersey" section below for one risk of choosing Advantage first.

Medicare Part D: Prescription Drugs

Part D covers prescription drugs, sold as a standalone plan paired with Original Medicare or built into a Medicare Advantage plan. Each plan sets its own premium, formulary, and pharmacy network, so the right plan depends on the specific drugs you take. In 2026, a Part D plan's deductible can be no higher than $615, and once your out-of-pocket spending on covered drugs reaches $2,100 for the year, you pay $0 for covered drugs for the rest of the calendar year (the old "donut hole" coverage gap was eliminated in 2025).6 If your income is limited, the federal Extra Help program (the Part D Low-Income Subsidy) can sharply cut these costs.7

Medigap in New Jersey

Medigap (Medicare Supplement) policies pay the deductibles and coinsurance Original Medicare leaves behind. The plans are standardized by letter, so a Plan G is the same coverage from any insurer, and only the price and service differ. If you are newly eligible to Medicare, Plans C and F are closed to you, and Plan G covers the same benefits as Plan F except the annual Part B deductible.8

Two New Jersey points matter. First, your strongest window is the federal 6-month Medigap Open Enrollment Period that starts once you are both 65 and enrolled in Part B; during it, insurers cannot deny you or charge you more for your health history.8 New Jersey does not add an annual "birthday rule" switch right.2 Second, and unusually, New Jersey protects beneficiaries under 65: people who get Medicare through disability are guaranteed access to a Medigap plan and cannot be charged a higher premium for being under 65. Under age 50, guaranteed-issue access is to Plan D through the state's contracted carrier, Horizon Blue Cross Blue Shield of New Jersey, and you must apply within six months of enrolling in Part B; between 50 and 64, Plan D is guaranteed-issue with any New Jersey Medigap insurer.2

One practical risk to weigh before choosing Medicare Advantage first: outside your one-time Medigap Open Enrollment Period, insurers in most situations can medically underwrite a Medigap application and deny you or charge more. Federal law does give you two 12-month "trial rights," and they are not the same. If you joined Advantage when you were first eligible for Medicare at 65, you can switch to Original Medicare within that first year and buy any Medigap policy sold by an insurer in New Jersey guaranteed-issue (Plan D or G rather than C or F if you were new to Medicare on or after January 1, 2020). If instead you dropped a Medigap policy to try Advantage for the first time, what you are guaranteed is that same policy back, and only if the insurer you had still sells it. Under either right, apply no earlier than 60 days before your Advantage coverage ends and no later than 63 days after.8 After that trial year passes, a later switch from Advantage to Medigap can be blocked by health underwriting, so weigh the decision carefully at 65.

Help Paying for Medicare

If your income and assets are limited, two kinds of help can cut your Medicare costs. The federal Extra Help program lowers Part D drug costs; in 2026 the full-benefit income limit is about $1,995 per month ($23,940 per year) for an individual and about $2,705 per month ($32,460 per year) for a married couple, with asset limits of $16,590 (individual) and $33,100 (married couple), rising to $18,090 and $36,100 if you tell Social Security you expect to use some of your resources for burial expenses. Those income figures are the limits for the 48 contiguous states and DC, New Jersey included; Alaska and Hawaii are figured from higher poverty guidelines, so the Extra Help income limits run higher there.7 The Medicare Savings Programs help pay the Part B premium and, for the QMB level, all Medicare cost-sharing; the 2026 federal resource standard is $9,950 (individual) and $14,910 (married couple). Enrolling in QMB, SLMB, or QI automatically qualifies you for Extra Help. QI has to be reapplied for every year, and none of these federal figures is a hard cutoff, because states can effectively raise both the income and the resource limits by disregarding certain income and resources, so apply rather than rule yourself out.9 New Jersey administers the Medicare Savings Programs through its Medicaid program; a SHIP counselor or your county office can screen you and help you apply.

If You Have Both Medicare and Medicaid

Some New Jerseyans qualify for both Medicare and New Jersey Medicaid (NJ FamilyCare). If you are one of them, Medicare pays first for covered care and Medicaid can help with premiums, cost-sharing, and services Medicare does not cover, including long-term care through New Jersey's Managed Long-Term Services and Supports (MLTSS) program. Dual-eligible special needs plans (D-SNPs) coordinate both.10 For the Medicaid side, see our New Jersey Medicaid guide.

Medicare Enrollment Periods

When you sign up matters, and missing your window without an exception can mean penalties that last as long as you keep the coverage. Most people enroll during their 7-month Initial Enrollment Period, which runs from 3 months before the month you turn 65 through 3 months after. Each fall, Medicare Open Enrollment (October 15 to December 7) lets you change Advantage and Part D plans, and the Medicare Advantage Open Enrollment Period (January 1 to March 31) lets people already in an Advantage plan make one change.11 If you delayed Part B and do not qualify for a Special Enrollment Period or a Medicare Savings Program, your premium rises 10% for each full 12-month period you could have had Part B but did not, and that penalty lasts as long as you have Part B; the Part D penalty likewise lasts as long as you have Part D, and generally does not apply if you had creditable drug coverage or you qualify for Extra Help.12 A SHIP counselor can map your exact dates.

If you are still working past 65 with group health coverage based on that current employment, you can delay Part B without penalty and use an eight-month Special Enrollment Period to sign up, counted from the month that job or coverage ends, whichever comes first. COBRA and retiree coverage do not count as coverage based on current employment, and if you are self-employed or your plan is not available to everyone at the company, ask your insurer whether it counts as employer group health plan coverage before you delay; if it does not, sign up at 65. This Special Enrollment Period does not apply if you are eligible for Medicare based on End-Stage Renal Disease (ESRD).13

How to Enroll in Medicare in New Jersey

Enrollment runs through the Social Security Administration (SSA), not a private broker. If you already receive Social Security benefits when you turn 65, you are enrolled in Parts A and B automatically; otherwise you sign up yourself.14
