QMB Plus is a Medicaid eligibility category for people who qualify for both the Qualified Medicare Beneficiary (QMB) program and full Medicaid coverage. This dual status means you get two layers of help: Medicaid pays your Medicare premiums, deductibles, and copays, and you also receive the full range of Medicaid benefits your state offers. It’s one of the most comprehensive assistance categories available to people enrolled in both Medicare and Medicaid.
How QMB Plus Differs From QMB Only
The distinction comes down to what else you qualify for beyond the core QMB benefit. A “QMB Only” individual meets the QMB income requirements (at or below 100% of the federal poverty level) and gets help paying Medicare costs: Part A and Part B premiums, deductibles, coinsurance, and copayments. That’s where QMB Only coverage stops.
A QMB Plus individual meets those same QMB standards but also qualifies for full Medicaid under their state’s rules. That means you receive everything a QMB Only person gets, plus all the benefits available to a fully eligible Medicaid recipient in your state. Those additional benefits vary by state but commonly include dental care, vision services, hearing aids, long-term care, transportation to medical appointments, and coverage for services Medicare doesn’t cover at all.
What QMB Plus Covers
The QMB side of the equation pays for your Medicare Part A premiums (if you don’t have premium-free Part A), Part B premiums, and all cost-sharing for Medicare-covered services. That means no deductibles, no coinsurance, and no copays on anything Medicare covers.
The full Medicaid side fills in the gaps. Depending on your state, this can include:
- Dental, vision, and hearing services that Medicare largely doesn’t cover
- Long-term care including nursing home stays and home-based care
- Non-emergency medical transportation to and from appointments
- Mental health and substance use services beyond what Medicare provides
- Personal care assistance for daily activities
For prescription drugs, QMB Plus status automatically qualifies you for Extra Help (the Part D Low Income Subsidy), which dramatically reduces what you pay at the pharmacy. If you have both QMB and full Medicaid, your copay for each covered drug is capped at $4.90 or less.
Billing Protections
One of the most important practical benefits of QMB status, whether QMB Only or QMB Plus, is a federal ban on balance billing. Medicare providers and suppliers, including pharmacies, are legally prohibited from billing you for any Medicare Part A or Part B cost-sharing. This applies to every provider who accepts Medicare, not just those who also accept Medicaid.
This protection is absolute. You cannot waive it or volunteer to pay, and providers cannot ask you to. If a provider does bill you for a Medicare deductible or copay, they are violating their Medicare provider agreement and can face sanctions. Any provider who has already collected cost-sharing money from a QMB beneficiary is required to issue a refund and recall any bills sent to collections.
If you receive a bill you believe you shouldn’t have, your state Medicaid office or the Medicare helpline (1-800-MEDICARE) can help resolve it.
Eligibility Requirements
To qualify as QMB Plus, you need to meet two sets of criteria simultaneously. First, you must be entitled to Medicare Part A and have income at or below 100% of the federal poverty level, with resources (savings, investments) that don’t exceed twice the Supplemental Security Income limit. For 2024, that resource cap is $9,430 for an individual and $14,130 for a couple in most states.
Second, you must independently qualify for full Medicaid in your state. Every state sets its own Medicaid income and asset thresholds, so the specific cutoff depends on where you live, your age, and whether you have a disability. In practice, most people who meet the QMB income threshold also qualify for full Medicaid, but this isn’t guaranteed in every state.
One significant trend: 13 states plus the District of Columbia (Alabama, Arizona, Connecticut, Delaware, Louisiana, Maine, Massachusetts, Mississippi, New Mexico, New York, Oregon, Vermont, and Washington) have eliminated the asset test for Medicare Savings Programs entirely. If you live in one of these states, your savings and investments won’t count against you when applying for QMB status, making it easier to qualify.
How to Apply
QMB Plus isn’t something you apply for as a single program. You apply for QMB through your state Medicaid agency, and if your income and resources also qualify you for full Medicaid, your state categorizes you as QMB Plus automatically. The application process is handled at the state level, typically through the same office that processes Medicaid applications.
You’ll generally need to provide proof of income (Social Security statements, pay stubs, pension documents), proof of resources (bank statements, investment accounts), your Medicare card or Medicare number, and identification. Many states allow you to apply online, by phone, or in person at a local Medicaid office. If you’re already enrolled in full Medicaid and become eligible for Medicare (by turning 65 or qualifying through disability), your state should evaluate you for QMB status, though it’s worth following up to confirm.
Dual Eligible Special Needs Plans
QMB Plus status also opens the door to Dual Eligible Special Needs Plans (D-SNPs), a type of Medicare Advantage plan designed specifically for people with both Medicare and Medicaid. These plans coordinate your Medicare and Medicaid benefits under one insurer, which can simplify everything from finding providers to managing prescriptions. D-SNPs often include extra benefits like over-the-counter health product allowances, fitness programs, and meal delivery after hospital stays. Enrollment in a D-SNP is optional, and QMB Plus is one of several Medicaid categories that qualify you.
