New Jersey Medicare follows the same federal rules as everywhere else, but two things set the state apart. It protects beneficiaries under 65 who want a Medigap policy, and it offers free, unbiased counseling through SHIP. Medicare itself is federal, so the parts, costs, and enrollment rules are the same; what changes by state is the help and the supplement market around them.
This guide explains the choices every New Jerseyan faces at 65, Original Medicare plus a Medigap supplement, or a Medicare Advantage plan, along with Part D drug coverage, what it all costs in 2026, the enrollment periods, and where to get free help deciding. The most useful number to save first: New Jersey SHIP at 1-800-792-8820.

Original Medicare: 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 (it's earned through work history), and pay the standard Part B premium each month, set federally for 2026. Original Medicare has deductibles and coinsurance and no annual out-of-pocket cap, which is why most people add either a Medigap supplement or choose Medicare Advantage. Here's how the two paths compare.
| Original Medicare + Medigap + Part D | Medicare Advantage (Part C) | |
|---|---|---|
| Providers | Any doctor or hospital that takes Medicare, nationwide | The plan's network, usually local |
| Referrals / prior authorization | Generally none | Often required |
| Out-of-pocket cap | None on Original Medicare; Medigap covers most cost-sharing | Yes, an annual cap |
| Extra benefits (dental, vision) | Not included | Often bundled |
| Monthly premiums | Part B + Medigap + Part D | Often low or $0, plus Part B |
Medicare Advantage in New Jersey (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. 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.
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. Plans differ in their formularies and pharmacy networks, so the right plan depends on the specific drugs you take. If your income is limited, the federal Extra Help (Low-Income Subsidy) program can sharply cut Part D costs.
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; only the price and service differ.
Two New Jersey points matter. First, your strongest window is the federal 6-month Medigap Open Enrollment Period that starts when you're both 65 and enrolled in Part B; during it, insurers can't deny you or charge more for your health history. New Jersey does not add an annual "birthday rule" switch right. Second, and unusually, New Jersey protects beneficiaries under 65: people who get Medicare through disability are guaranteed access to a Medigap plan and can't 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; between 50 and 64, Plan D is guaranteed-issue with any New Jersey Medigap insurer.
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 for Part D drug costs, and the Medicare Savings Programs, which help pay Part B premiums and sometimes other cost-sharing. 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're one of them, Medicare pays first for covered care and Medicaid can help with premiums, cost-sharing, and services Medicare doesn't cover, including long-term care through MLTSS. Dual-eligible special needs plans coordinate both. For the Medicaid side, see our New Jersey Medicaid guide.
Medicare Enrollment Periods
When you sign up matters, and missing your window can mean lifelong penalties. Most people enroll during their Initial Enrollment Period around their 65th birthday. There's an annual Open Enrollment (October 15 to December 7) to change Advantage and Part D plans, and a Medicare Advantage Open Enrollment in early each year. If you delayed Part B or Part D without other qualifying coverage, late penalties can apply. A SHIP counselor can map your exact dates.

Frequently Asked Questions
The same two main paths as everywhere: Original Medicare (Parts A and B) with an optional Medigap supplement and a Part D drug plan, or a Medicare Advantage plan that bundles coverage through a private insurer's network. Which is better depends on your doctors, your drugs, and how you weigh flexibility against cost.
Yes, and it's a real advantage. New Jersey guarantees under-65 disabled Medicare beneficiaries access to a Medigap plan with no age-based premium surcharge. Under 50, that's Plan D through the state's contracted carrier; ages 50 to 64, Plan D with any New Jersey Medigap insurer.
