With a New Jersey fully integrated dual eligible special needs plan (FIDE SNP), one plan covers your Medicare care and Medicaid-only services such as long-term nursing facility stays. New Jersey's Medicaid agency says members get a single plan, a single ID card and a single network of providers for Medicare and NJ FamilyCare (Medicaid). For a family arranging personal care or nursing home care for a parent, that means one plan answers for the service, instead of two programs to sort out. Before you join, check the plan's doctors, drug list and costs, and know how to leave if it doesn't work for you.

What Is a FIDE SNP in New Jersey?

New Jersey's Medicaid agency, the Division of Medical Assistance and Health Services (DMAHS), tells New Jersey residents who have both Medicare and Medicaid that they can enroll in a FIDE SNP. DMAHS describes a FIDE SNP as a special kind of Medicare managed care plan that coordinates all covered Medicare and Medicaid benefits in one health plan. New Jersey's Medicaid program runs through NJ FamilyCare, which DMAHS administers at the state level.

Federal rules set what makes a plan "fully integrated." Under 42 CFR 422.2, a FIDE SNP is a dual eligible special needs plan (D-SNP) run by a single company that holds both a Medicare Advantage contract with the Centers for Medicare & Medicaid Services (CMS) and a Medicaid managed care contract with the state. For plan year 2025 and later, a FIDE SNP company's Medicaid contract must cover Medicare cost-sharing, long-term services and supports (including at least 180 days of nursing facility coverage in the plan year), behavioral health, home health, and medical supplies and equipment, to the extent the state's Medicaid program covers them for people eligible to enroll. From 2025 a FIDE SNP must also operate with what CMS calls exclusively aligned enrollment.

In practice, joining a New Jersey FIDE SNP means one company handles both programs for you. The Medicaid and CHIP Payment and Access Commission (MACPAC) reported in a June 2024 report on state Medicaid agency contracts, describing contract year 2023, that New Jersey directly capitates coverage of Medicaid services to the D-SNP, meaning the D-SNP also holds the Medicaid managed care contract for its enrollees.

FIDE SNPs are rare nationally. The Medicare Payment Advisory Commission (MedPAC) reported that in 2024 only 3 percent of dually eligible beneficiaries were in a FIDE SNP, the most integrated type of D-SNP. For how the federal categories work in every state, see our guide to fully integrated dual eligible SNPs.

What Does a FIDE SNP Cover in New Jersey?

DMAHS says most services a FIDE SNP covers are Medicare services, and a few are covered only by Medicaid. The difference for a member is that the FIDE SNP covers the service directly, so there's no need to work out whether Medicare or Medicaid would normally pay.

Type of service Who would normally pay In a FIDE SNP
Most covered health services Medicare Covered by the FIDE SNP
Dental, vision, hearing aids and fittings Medicaid only Covered by the FIDE SNP
Certain private duty nursing services, medical day care, personal care assistance Medicaid only Covered by the FIDE SNP
Long-term nursing facility stays Medicaid only Covered by the FIDE SNP
Care beyond Medicare's limits that Medicaid covers Generally Medicaid pays what Medicare doesn't Covered by the FIDE SNP

The table restates DMAHS's description of FIDE SNP coverage, and DMAHS calls its Medicaid-only list examples ("including"), not a complete list. MACPAC's June 2024 report likewise found that in New Jersey all services were included in the D-SNP's capitated rate for contract year 2023. Ask any plan you're considering for its full benefit list in writing.

FIDE vs. HIDE: Which Kinds of Dual Plans Does New Jersey Have?

New Jersey doesn't limit its dual plans to FIDE SNPs. CMS's contract year 2026 integration-status file (key findings as of November 2025) lists New Jersey both among the states with FIDE SNPs and among the states with highly integrated (HIDE) SNPs, and does not list New Jersey among the states with coordination-only D-SNPs.

Integration level MedPAC's description Share of all dual eligibles, 2024 Listed for New Jersey by CMS, CY2026
Coordination-only D-SNP Least integrated 27 percent No
Highly integrated (HIDE SNP) Highly integrated 15 percent Yes
Fully integrated (FIDE SNP) Most integrated 3 percent Yes

The national shares come from MedPAC's 2024 figures, and the New Jersey column comes from CMS's contract year 2026 file. CMS's state lists don't say which New Jersey plan is which type. When a company offers you a "dual" plan, ask whether it is a FIDE SNP or a HIDE SNP, and whether it also runs your NJ FamilyCare plan.

One federal protection depends on the type. FIDE SNPs, and HIDE SNPs with exclusively aligned enrollment, are "applicable integrated plans" under 42 CFR 422.561, which combine Medicare and Medicaid grievances and appeals into one process rather than two separate tracks. If a New Jersey FIDE SNP denies a service, follow the appeal instructions on the plan's denial notice; for decisions about NJ FamilyCare eligibility itself, see New Jersey Medicaid appeals and fair hearings. For contract year 2027, CMS also addressed its integrated model member materials (handbook, ID card, and provider and pharmacy directory) to applicable integrated plan D-SNPs in 23 states and territories, New Jersey among them.

Who Can Join a New Jersey FIDE SNP?

DMAHS offers FIDE SNPs to New Jersey residents who have both Medicare and Medicaid. Under 42 CFR 422.2, a D-SNP is a Medicare Advantage plan for people entitled to medical assistance under their state's Medicaid plan. Medicare's monthly "integrated care" enrollment window is open only to full-benefit dual eligibles, not to partial-benefit dual eligibles or people with Extra Help alone, and it must be used to line up your D-SNP with a Medicaid managed care plan.

That leaves two groups who should check before counting on a FIDE SNP:

DMAHS's FIDE SNP page is the place to start for the state's current list of FIDE SNP plans, and the Medicare Plan Finder shows which plans are offered at your address.

What Will You Pay?

A FIDE SNP's costs follow federal rules, and the plan's own design decides the rest. Here's how the federal rules work for 2026:

So ask each plan, in writing if you can, what its monthly premium is after Extra Help and what you'd pay for your own prescriptions. A New Jersey SHIP counselor can check the numbers with you for free (see below). For more on the drug subsidy, see our guide to Medicare Extra Help.

How to Join, and How Often You Can Switch

Full-benefit dual eligibles don't have to wait for Medicare's fall open enrollment. The contract year 2025 Medicare Advantage and Part D final rule (CMS-4205-F) created two monthly options:

  1. Joining: A once-per-month "integrated care" special enrollment period lets full-benefit dual eligibles enroll in an aligned integrated D-SNP, meaning a fully integrated, highly integrated or applicable integrated plan.
  2. Leaving: A once-per-month special enrollment period lets dual eligibles and people with Extra Help pick a stand-alone Part D drug plan in any month. Medicare.gov describes that right as dropping a Medicare Advantage plan with drug coverage and returning to Original Medicare by joining a stand-alone drug plan, with the change taking effect on the first day of the next month. The monthly stand-alone drug plan option isn't available while you're identified as a potential at-risk or at-risk beneficiary under a Part D drug management program.

Starting with contract year 2025, CMS-4205-F also ended the old quarterly special enrollment period for dual eligibles and Extra Help enrollees, which could be used once in each of the first three quarters of the year. If a mailer or older web page describes quarterly change windows, it is describing the rule before 2025.

To join, contact the plan you've chosen or enroll through the Medicare Plan Finder. Before you leave a FIDE SNP, call NJ FamilyCare or SHIP and ask which NJ FamilyCare plan your Medicaid benefits will move to, so both programs have a home the day the change takes effect. Our guide to Medicare special enrollment periods lists the other times you can change coverage.

FIDE SNPs and MLTSS Long-Term Care

New Jersey delivers Medicaid long-term services and supports through Managed Long Term Services and Supports (MLTSS), in which an NJ FamilyCare managed care plan coordinates all services, whether at home, in assisted living, in community residential services or in a nursing home. Qualifying for MLTSS takes clinical eligibility, financial eligibility, and an age or disability requirement (65 or older, or under 65 and determined blind or disabled by the Social Security Administration or the State of New Jersey).

A FIDE SNP covers the Medicaid-only long-term care services listed in the coverage table above directly, so there's no question of which program pays. If your parent already gets MLTSS through an NJ FamilyCare plan, ask that plan and any FIDE SNP you're weighing how the care manager, aides and authorized hours carry over before you switch. Our guide to New Jersey MLTSS covers who qualifies and how to apply.

What Changes for Dual Plans in 2027 and 2030?

The federal aligned-enrollment rule at 42 CFR 422.514(h), as CMS's April 2026 questions and answers explain it, turns on one question: does the company behind your D-SNP, or a company under the same parent, also run a Medicaid managed care plan for full-benefit dual eligibles where you live? A FIDE SNP is already run by a single company that holds both the Medicare and the Medicaid contract.

  • 2027: Starting in 2027, a D-SNP whose company (or a company under the same parent) also contracts with the state as a Medicaid managed care organization enrolling full dual eligibles in the same service area may only take new enrollees who are in, or enrolling in, that affiliated Medicaid plan.
  • 2027 to 2030: An existing member of such an affiliated D-SNP who isn't in the company's Medicaid plan may stay in the D-SNP until 2030.
  • 2030: From 2030, an affiliated D-SNP may generally only enroll or keep members who are also in the company's Medicaid plan, and the company must disenroll D-SNP members who aren't. The plan may still keep a member through its deemed continued eligibility period after a temporary loss of Medicaid (see below).
  • Fee-for-service exception: The contract year 2027 final rule lets a company enroll full-benefit dual eligibles who get Medicaid through fee-for-service into a coordination-only D-SNP or HIDE SNP, where the state does not require all full-benefit dual eligibles to join Medicaid managed care and the state Medicaid agency's contract allows it, and this exception continues in 2030 and beyond.
  • Unaffiliated D-SNPs: A D-SNP whose company doesn't run a Medicaid managed care organization serving full dual eligibles in the state is outside these limits.

Applicable integrated plan D-SNPs must also move to one integrated member ID card for both Medicare and Medicaid, and a single integrated health risk assessment, no later than contract year 2027. If you're in a D-SNP from one company and an NJ FamilyCare plan from another, ask SHIP before 2027 whether your D-SNP is affected and whether the fee-for-service exception applies to you.

What Happens If Your NJ FamilyCare Lapses?

A D-SNP is a plan for people entitled to Medicaid, so a missed NJ FamilyCare renewal can put your membership at risk. Federal rules give special needs plans a cushion. Under 42 CFR 422.52(d), when a special needs plan finds that an enrollee no longer qualifies but can reasonably be expected to qualify again within six months, the enrollee is deemed to stay eligible for at least 30 days and no more than six months. CMS's contract year 2027 guidance says each special needs plan picks the length of that period, from one to six months, as long as it applies the same policy to all members and tells them what it is.

  • If you don't requalify in time: A member who doesn't requalify within the plan's deemed continued eligibility period is expected to be disenrolled at the end of it, and the plan should send a disenrollment notice at least 30 days before.
  • Your enrollment window: A person who loses special needs plan eligibility gets a special enrollment period that starts the month the status changes and ends three calendar months after the disenrollment takes effect.

Ask your FIDE SNP how long its deemed continued eligibility period is, and return NJ FamilyCare renewal paperwork as soon as it arrives. Our guide to New Jersey Medicaid recertification and renewal explains how renewal works.

Where to Get Free Help in New Jersey

The New Jersey State Health Insurance Assistance Program, known as SHIP and administered by the New Jersey Department of Human Services, gives free help to Medicare beneficiaries with questions about their health insurance. SHIP counselors don't sell, recommend or endorse any plan or insurance company; they give you information so you can decide. Counseling sites operate in all 21 New Jersey counties, and the SHIP Information Center is at 1-800-792-8820. Appointments are held by phone, virtually or in person, and you can also reach a counselor through your County Office on Aging. Our guide to New Jersey SHIP explains what a session covers.

Frequently Asked Questions

Can a parent in a nursing home join a New Jersey FIDE SNP?

DMAHS offers FIDE SNPs to New Jersey residents who have both Medicare and Medicaid, and it lists long-term nursing facility stays among the Medicaid-only services a New Jersey FIDE SNP covers directly., Under CMS's 2026 Extra Help table, a full-benefit dual eligible living in a nursing home pays $0 per covered Part D drug. Before switching, ask the plan whether your parent's nursing home is in its network.

Will a New Jersey FIDE SNP let me keep my doctors?

Check before you join. DMAHS says a New Jersey FIDE SNP gives members a single network of providers for both Medicare and NJ FamilyCare services. Look up each doctor, your pharmacy and any home care agency in the plan's directory, or call the plan and ask.

Does a FIDE SNP cover assisted living in New Jersey?

DMAHS's list of Medicaid-only services a New Jersey FIDE SNP covers doesn't name assisted living, but DMAHS presents that list as examples rather than a complete list. In NJ FamilyCare, an MLTSS managed care plan coordinates long-term care services whether the member lives at home, in an assisted living facility or in a nursing home. If your parent lives in or is moving to assisted living, ask the FIDE SNP in writing which services it covers in an assisted living residence and whether that residence is in its network.
