Dual Eligible: Medicare and Medicaid Together (2026)

If you qualify for both Medicare and Medicaid, you hold the most generous coverage in the system, and being dual eligible can erase nearly all of your out-of-pocket costs. Millions of Americans are in this position, where Medicare covers the medical bills, Medicaid fills the gaps including long-term care, and prescription help arrives automatically. This guide explains the two kinds of dual eligibility, how the programs coordinate, what each pays, and the plans that combine them.

What dual eligible means

A person is "dual eligible" when they qualify for both Medicare and Medicaid at the same time. Medicare is the federal health insurance program tied mostly to age and work history. Medicaid is the joint federal-state program based on income and assets. Having both is powerful because each program covers what the other does not.1

There are two groups, and which one you fall into decides how much help you get.

Full vs. partial dual eligibility

The line between full and partial duals is about whether you have full Medicaid or only premium and cost-sharing help. Full duals get Medicaid's complete benefit package layered on top of Medicare. Partial duals get a narrower form of help that pays Medicare's premiums and, in one case, its cost-sharing, but does not open the door to Medicaid's broader services such as long-term custodial care.1

How Medicare and Medicaid coordinate

The order of payment is fixed. Medicare is the primary payer and pays first on covered services. Medicaid is the secondary payer and pays second, picking up Medicare's premiums and cost-sharing and covering services Medicare leaves out.1

The most important of those gaps is long-term custodial care. Medicare pays for skilled nursing only on a short-term, post-acute basis, and it does not pay for ongoing help with daily activities, the kind of care most people mean by "nursing home." Medicaid does. For a full dual in a nursing facility, Medicaid covers the cost of that care, which is a large part of why dual eligibility matters financially. Nursing-facility residents typically contribute most of their monthly income, less a small personal needs allowance, toward the cost of care regardless of which plan they have.

Coordination also means you rarely choose between the programs. They run together: Medicare processes the claim, then Medicaid handles the remainder according to its rules.

The QMB cost protection

The strongest cost protection in dual eligibility belongs to the Qualified Medicare Beneficiary (QMB) group. Under federal law, Medicare providers, suppliers, and pharmacies are prohibited from billing a QMB enrollee for Medicare Part A and Part B cost-sharing, meaning deductibles, coinsurance, and copays. The Centers for Medicare & Medicaid Services (CMS) confirms this balance-billing prohibition.1

CMS reports that QMB enrollees are still wrongly billed in practice. If you are in the QMB group and a provider sends you a bill for Medicare cost-sharing, that bill is improper: you have no legal obligation to pay it, and a provider who bills you improperly is subject to sanctions and must recall the bill and refund any cost-sharing already collected. The prohibition binds every Original Medicare and Medicare Advantage provider and supplier, not only those that accept Medicaid. Keep your QMB documentation, and tell the provider's billing office you are a QMB enrollee.1

The QMB tier is one of several Medicare Savings Programs. The tiers differ by income and by what they pay, as summarized by Medicare.gov's Savings Programs page.

Income figures are approximate and may reflect state disregards of income and of resources, so confirm current limits with your state Medicaid agency. They also apply only in the 48 contiguous states and the District of Columbia. Alaska and Hawaii have higher income limits: for 2026 the QMB limit for an individual is $1,683 in Alaska and $1,550 in Hawaii, and the SLMB and QI tiers rise in step.2 The 2026 federal resource (asset) standard for all three tiers is $9,950 for an individual and $14,910 for a married couple, and that standard is not raised for Alaska or Hawaii the way their income limits are.2 It is not an absolute cutoff: states can effectively raise both the income and the resource limits by disregarding certain income and resources, and some have dropped the resources test altogether, so apply rather than rule yourself out.2

Automatic Extra Help for prescriptions

Anyone who has full Medicaid, or who qualifies for QMB, SLMB, or QI, automatically qualifies for Extra Help, the full Part D Low-Income Subsidy (LIS). You do not file a separate application. This matters because Extra Help sharply lowers drug costs.1,2

One savings program is the exception. QDWI, a narrow tier that pays the Part A premium for certain working people with disabilities who lost premium-free Part A, does not carry Extra Help with it; federal rules deem only the QMB, SLMB, and QI groups automatically eligible for the full subsidy.2

Geography is a second exception. Extra Help is not available in Puerto Rico, the U.S. Virgin Islands, Guam, the Northern Mariana Islands, or American Samoa, so dual eligibility does not bring the subsidy with it in those places. Residents of those areas should call their State Medical Assistance (Medicaid) office about the other programs available there.3

In 2026, $5.10 for a generic and $12.65 for a brand-name covered drug is the ceiling on what a full Extra Help enrollee pays rather than a flat price, and everyone pays $0 once out-of-pocket drug costs reach the $2,100 catastrophic threshold, per the CMS CY2026 Low-Income Subsidy limits. Because of the Inflation Reduction Act, the old partial-subsidy tier was eliminated in 2024, so everyone who qualifies now receives the full subsidy rather than a reduced version.3

Dual eligibles mostly land below that ceiling. Someone who has full Medicaid coverage and is in the QMB group pays no more than $4.90 for each covered drug in 2026.4 CMS's 2026 maximum cost-sharing table for the subsidy fills in the rest of the ladder: a full-benefit dual eligible with income at or below 100% of the Federal Poverty Level pays $1.60 for a generic and $4.90 for a brand-name drug, one who is institutionalized or receiving home and community-based services pays $0 for both, and only a full-benefit dual between 100% and 150% of the FPL, or someone on Extra Help without full Medicaid, pays the $5.10 and $12.65 figures. The Part D deductible is $0 in every one of those categories.3

Plans that combine both programs

Dual-eligible Special Needs Plans (D-SNPs) and the more tightly integrated FIDE-SNPs are Medicare Advantage plans built to coordinate Medicare and Medicaid in one plan, with one card and one care team. A Fully Integrated Dual Eligible Special Needs Plan (FIDE-SNP) holds a capitated Medicaid contract covering primary, acute, behavioral health, and long-term services, so the same plan manages both sides of your coverage.4

Because federal law bars providers from billing enrollees in the QMB group for Medicare Part A and Part B cost-sharing, a QMB-enrolled dual in a FIDE-SNP faces $0 deductibles, $0 coinsurance, and $0 copays on the Medicare side. For plan year 2025 and later, a FIDE-SNP's own capitated Medicaid contract must also cover Medicare cost-sharing, without regard to that definition's limit to qualified Medicare beneficiaries.4 A $0 monthly premium is a plan-design feature that varies by plan and state, not a legal guarantee. Integration also simplifies appeals: a FIDE-SNP combines Medicare and Medicaid appeals into a single process. Availability and the exact plan tier vary by state and county, and CMS continues to tighten the integration and enrollment-alignment requirements these plans must meet. The dedicated guide below walks through how these plans work, where they operate, and what is changing.4

How to apply for dual coverage

If you already have Medicare, the path to dual eligibility runs through Medicaid and the Medicare Savings Programs, both administered by your state. Two points are easy to miss. First, the savings-program asset limit is higher than many people assume, so applicants who think they have too much in savings often still qualify. Second, qualifying for QMB, SLMB, or QI triggers automatic Extra Help, so a single application can lower both your premium and your drug costs. QDWI, the fourth savings program, is the one tier that does not.2

Two situations deserve special attention. If one spouse enters a nursing home or long-term care while the other stays in the community, federal spousal-impoverishment rules let the at-home spouse keep a protected share of the couple's income and assets when the state tests Medicaid eligibility, so the applying spouse can qualify without leaving the other destitute. Our guide to spousal impoverishment protections walks through how the state figures that protected share. And if your income lands just above the QMB line, you may still qualify for the SLMB or QI tier, which pays your Part B premium and, on its own, still unlocks automatic Extra Help.2
