Medicaid is a joint federal-state program and every state runs it differently. This guide covers what is consistent across all states, where state rules vary, and how to use your coverage from day one. If you have both Medicaid and Medicare, there is a section specifically for that combination.
Topic one
Your Medicaid card
Medicaid cards look different in every state. In many states you will not receive a physical card at all - your coverage is verified electronically at the provider's office. Here is what to confirm when your coverage starts.
Confirm immediately
Your Medicaid ID number
Your Medicaid ID number is how providers verify your coverage. In states that issue physical cards, it is printed on the card. In states that use electronic verification, your ID number is in your eligibility letter or your state Medicaid portal. Keep it with you and memorize it.
Ask your state Medicaid office or check your eligibility notice for your ID number if you are unsure
Before your first appointment
Confirm the provider accepts Medicaid
Medicaid provider networks are narrower than Medicare. Not every physician, specialist, or facility accepts Medicaid, and acceptance varies by state and plan. Always confirm before scheduling. Do not assume that because a provider accepted Medicaid last year, they still do.
Call ahead and ask specifically: "Do you accept my state's Medicaid program?" Name the state and your plan if you are in managed care
Medicaid benefits and rules vary significantly by state. Federal law sets a floor - states can and do add coverage above it.
The federal Medicaid program requires states to cover certain mandatory services: hospital care, physician visits, lab and X-ray, nursing facility care, and others. States may add optional benefits like dental, vision, hearing aids, and personal care services. What your Medicaid covers depends on which state you live in. Your state Medicaid agency website is the authoritative source for what your specific plan covers.
Topic two
What Medicaid covers
Federal law requires all state Medicaid programs to cover a core set of services. Many states cover significantly more. The most important gap to understand is long-term care.
What Medicare does not cover but Medicaid often does
Long-term nursing home care
Medicare covers skilled nursing care short-term. Medicaid is the primary payer for long-term nursing home stays when Medicare ends.
Medicaid covers
Personal care services at home
Help with bathing, dressing, meals, and daily activities. Medicare does not cover custodial care. Medicaid home and community-based services waiver programs often do.
Varies by state
Dental, vision, and hearing
Not covered by Original Medicare for most adults. Many state Medicaid programs cover routine dental, vision exams, and hearing aids.
Varies by state
Non-emergency medical transportation
Rides to and from medical appointments. Medicare does not cover this. Medicaid covers it in most states.
Most states cover
Medicaid does not automatically cover all long-term care. Asset limits and program rules determine who qualifies for nursing home Medicaid specifically.
Qualifying for regular Medicaid does not automatically mean you qualify for nursing home coverage under Medicaid. Long-term care Medicaid has separate asset and income rules, and in most states requires spending down assets before Medicaid pays. If nursing home care is a possibility, consult a certified elder law attorney before assets are spent. Planning before a crisis preserves far more than planning after one.
Topic three
Medicare and Medicaid together
If you have both Medicare and Medicaid, you are a dual-eligible beneficiary. About 12 million Americans are dual-eligible. The two programs interact in specific ways that can significantly reduce your out-of-pocket costs - but only if you understand how the coordination works.
Medicare pays first
Primary payer
For services covered by both programs, Medicare is always the primary payer. It pays its portion of the claim first, then submits the remainder to Medicaid.
In most cases you will not receive a bill for services covered by both - Medicare pays, then Medicaid picks up the remainder
Medicaid pays second
Secondary payer
After Medicare pays, Medicaid covers the remaining cost-sharing - deductibles, coinsurance, and copays - up to the Medicaid limit. For most dual-eligible beneficiaries this reduces out-of-pocket costs to near zero.
If you are receiving bills for Medicare cost-sharing, check whether your Medicaid should be covering it
Medicare Savings Programs (MSPs) are Medicaid programs that pay some or all of your Medicare premiums, deductibles, and cost-sharing. There are four levels:
Qualified Medicare Beneficiary (QMB): Pays Part A and Part B premiums, deductibles, and cost-sharing. The most comprehensive level. Providers are prohibited from billing QMB beneficiaries for Medicare cost-sharing amounts.
Specified Low-Income Medicare Beneficiary (SLMB): Pays Part B premium only.
Qualifying Individual (QI): Pays Part B premium only. Limited slots available, first-come first-served each year.
Qualified Disabled and Working Individual (QDWI): Pays Part A premium for certain working disabled individuals under 65.
If you have full Medicaid and Medicare, you are likely already enrolled in the QMB program. If you have Medicare but only partial or no Medicaid, you may still qualify for an MSP. Apply through your state Medicaid office. Income and asset limits are higher than for full Medicaid.
A Dual Eligible Special Needs Plan (D-SNP) is a Medicare Advantage plan specifically designed for people who have both Medicare and Medicaid. D-SNPs coordinate both benefits in a single plan and often include additional benefits not available in standard Medicare Advantage.
D-SNPs can simplify the dual-eligible experience by having a single card, single care team, and integrated care management. Not all areas have D-SNPs available. Enrollment is limited to people with both Medicare and Medicaid. Your SHIP counselor can help you evaluate whether a D-SNP makes sense for your situation.
Important: Enrolling in a D-SNP is a choice, not a requirement. You can keep Original Medicare and Medicaid as separate programs if you prefer. Compare the D-SNP network and benefits carefully against your current situation before switching.
If you have full Medicaid and Medicare, you are automatically enrolled in the Extra Help program (also called Low Income Subsidy or LIS). Extra Help substantially reduces Part D drug costs: lower premiums, reduced deductibles, and reduced copays at the pharmacy.
With full Extra Help, you pay no more than a few dollars for each covered prescription. The exact amounts change annually. You do not need to apply if you have full Medicaid - enrollment is automatic. If you lose Medicaid eligibility, notify Social Security promptly as Extra Help eligibility may also change.
Topic four
Medicaid managed care
Most states deliver Medicaid benefits through managed care organizations - private health plans that contract with the state. If your state uses managed care, you may have been assigned to a plan or asked to choose one.
In managed care states, your Medicaid benefits come through a private plan, not directly from the state. Your card will show the plan's name, not just "Medicaid."
Medicaid managed care plans contract with the state to deliver Medicaid benefits. The plan manages your care, maintains a network of providers, and authorizes services. The state sets minimum requirements but the plan handles day-to-day coverage. This means your provider network, prior authorization requirements, and covered drug formulary all depend on which managed care plan you are in.
1
Know which plan you are in and how to contact them
Your managed care plan card has a member services number. Save it. Questions about prior authorization, network providers, covered services, and claims all go to your plan - not to the state Medicaid office directly.
2
Confirm your primary care provider is assigned and in-network
Most Medicaid managed care plans require a primary care provider (PCP) assignment. Confirm who your assigned PCP is, verify they are accepting new Medicaid patients, and schedule an initial appointment to establish care. Specialist referrals typically flow through the PCP in managed care.
3
Understand your plan's prior authorization requirements
Medicaid managed care plans require prior authorization for many services - specialist visits, imaging, certain medications, durable medical equipment. Always ask whether a service requires prior authorization before scheduling. A service provided without required prior authorization may not be covered even if the service itself is covered by Medicaid.
4
Know your right to change plans during open enrollment
Most states have an annual period when you can change your Medicaid managed care plan. You may also be able to change for cause - if your PCP leaves the network, if you move, or if you have quality of care concerns. Contact your state Medicaid office to understand your state's plan change rules.
Topic five
Redetermination - keeping your coverage
Medicaid eligibility must be renewed periodically - typically every twelve months. This is called redetermination. If you miss it, your coverage ends. This is one of the most common reasons people lose Medicaid.
Medicaid will send you a renewal notice. You must respond or your coverage ends - even if nothing in your situation has changed.
Your state Medicaid agency will mail a renewal packet to the address they have on file. If that address is outdated, you will not receive the notice and your coverage will lapse. Keep your address current with your state Medicaid office. When the renewal notice arrives, complete and return it promptly - do not set it aside. Deadlines are real and missing them causes coverage gaps that require a new application to fix.
1
Keep your address current with your state Medicaid office
This is the single most important action to protect your Medicaid. Update your address any time you move, even temporarily. Most states allow address updates online through their Medicaid portal, by phone, or in person at a local office.
2
Watch for the renewal notice and respond immediately
Renewal notices typically arrive 60 to 90 days before your coverage renewal date. When it arrives, complete and return it by the deadline shown. If you need help completing the renewal, contact your local Medicaid office, a SHIP counselor, or a benefits enrollment center.
3
Report income or household changes promptly
If your income, household size, or other circumstances change, report it to your state Medicaid office promptly. Changes can affect your eligibility and your coverage type. Reporting changes you are required to report protects you from retroactive terminations and repayment demands.
4
If coverage lapses, reapply immediately - do not wait
If your Medicaid ends due to a missed redetermination, reapply as soon as you notice. In many states coverage can be reinstated with limited or no gap if the lapse was due to an administrative error. Apply online through your state's Medicaid portal or call your state Medicaid office directly.
Topic six
Coverage gaps to know
Medicaid is broad but not unlimited. Understanding where coverage ends helps you plan.
Key Medicaid coverage limits
Out-of-state coverage
Medicaid is state-specific. If you travel or move to another state, your coverage may not transfer. Emergency care is covered in all states. Non-emergency out-of-state care generally is not.
Plan ahead when traveling
Estate recovery
For beneficiaries 55 and older, states are required to seek reimbursement from the estate for Medicaid costs for nursing home and other long-term care services after death. This is called Medicaid estate recovery and it can affect assets left to heirs.
Consult elder law attorney
Provider network limits
Medicaid networks are narrower than Medicare. Not all providers accept it and acceptance varies by specialty and geography. Rural areas often have limited Medicaid provider options.
Always confirm in advance
Topic seven

About the information on this page.
Medicaid rules vary significantly by state. Federal requirements come from the Centers for Medicare & Medicaid Services at medicaid.gov. State-specific eligibility, benefits, and managed care rules are set by each state Medicaid agency. Verify your state's current rules directly with your state Medicaid office before making coverage or eligibility decisions.
