Medicaid and QMB: How Do They Work Together?
QMB is a Medicare Savings Program run through Medicaid. If you qualify, your state Medicaid program helps pay certain Medicare costs, such as Part A and Part B premiums and Medicare-covered deductibles, coinsurance, and copayments. Some people have QMB only, while others have QMB plus full Medicaid. Either way, Medicare providers generally cannot bill QMB members for Medicare-covered Part A and Part B cost sharing.
What is the difference between Medicaid and QMB?
Medicaid is a joint federal and state program that can provide health coverage for people with limited income and resources. Benefits and eligibility rules vary by state.
QMB stands for Qualified Medicare Beneficiary. It is one of the Medicare Savings Programs. QMB is handled through Medicaid, but it is not always the same as having full Medicaid health coverage.
In plain terms, QMB is Medicaid help with Medicare costs. Full Medicaid may also cover additional Medicaid benefits, depending on your state and eligibility category.
How does QMB help pay Medicare costs?
If you qualify for QMB, your state Medicaid program helps with Medicare Part At A and Part B costs. This may include:
- Part A premiums, if you owe a Part A premium
- Part B premiums
- Medicare-covered deductibles
- Medicare-covered coinsurance
- Medicare-covered copayments
When a service is covered by Medicare, Medicare generally pays first. Medicaid may then be responsible for Medicare cost sharing, subject to federal and state payment rules. The provider should not collect Medicare Part A or Part B cost sharing from you if you are in QMB.
Can you have both full Medicaid and QMB?
Yes. Some people qualify for QMB-only, which means Medicaid helps with Medicare costs but does not provide the full Medicaid benefit package. Others qualify for QMB Plus, which means they receive QMB help and full Medicaid benefits.
If you have full Medicaid as well as QMB, Medicaid may help with services Medicare does not cover, but only if those services are covered under your state Medicaid program and you use providers that meet Medicaid rules.
Can providers bill you if you have QMB?
For Medicare-covered Part A and Part B services and items, Medicare providers generally are not allowed to bill QMB members for deductibles, coinsurance, or copayments. This protection applies in Original Medicare and Medicare Advantage, and it is not limited to providers who accept Medicaid.
You may still receive a bill for a small Medicaid copayment if one applies under your state’s rules. You may also be responsible for services that Medicare does not cover, unless another program such as full Medicaid covers them.
To help avoid billing problems, show your Medicare card and your Medicaid or QMB card each time you get care.
What limitations should you know?
QMB is powerful help, but it has limits:
- QMB does not automatically mean you have full Medicaid benefits.
- QMB protections apply to Medicare-covered Part A and Part B cost sharing, not every possible health care charge.
- State Medicaid rules affect eligibility, covered Medicaid services, and how Medicaid pays providers.
- Some states use different income or resource counting rules, so you may need to apply even if you are not sure you qualify.
- QMB benefits are generally not retroactive in the same way some Medicaid benefits can be.
Because Medicaid is state-administered, your state Medicaid office is the best place to confirm how QMB and any full Medicaid benefits apply to your situation.
What should you do if you get a bill while on QMB?
If you get a bill for Medicare-covered Part A or Part B cost sharing, contact the provider and tell them you are in the QMB program. Give them a copy of your Medicaid or QMB card if needed.
If you have Original Medicare, your Medicare Summary Notice may show that you are in QMB and should not be billed for Medicare-covered cost sharing. If the bill is not corrected, you can contact Medicare or your state Medicaid office for help.
