Medicaid Frequently Asked Questions
Updated August 2026
This FAQ covers the questions we hear most often: who qualifies, what the program actually pays for, and how to apply. Medicaid and CHIP together cover about 73.9 million people, per CMS (April 2026). Because states administer their own programs under federal guidelines, many answers depend on where you live — verify specifics with your state Medicaid agency.
Eligibility questions
Who can get Medicaid, income rules, and special circumstances.
Who qualifies for Medicaid?
Medicaid covers low-income adults, children, pregnant women, elderly adults, and people with disabilities. In states that expanded Medicaid under the ACA, most adults with income at or below 138% of the Federal Poverty Level qualify. Non-expansion states have narrower rules that often exclude childless adults regardless of income — check your state agency for current limits.
Does income alone determine Medicaid eligibility?
Not always. For most non-elderly adults and children, eligibility is based on Modified Adjusted Gross Income (MAGI), which is income-only with no asset test. For seniors, people with disabilities, and long-term care applicants, states apply both income limits and asset (resource) tests — typically capping countable assets at $2,000 for a single person, though amounts vary by state.
Can I qualify for Medicaid if my state did not expand it?
In non-expansion states, eligibility is much narrower. Most working-age adults without children do not qualify, even at very low incomes. If you fall in the coverage gap — income too high for Medicaid but too low for Marketplace subsidies — you may have limited options. Per KFF research, roughly 1.2 million people remain in this gap currently.
Are former foster youth automatically covered?
Yes, in all 50 states and DC. Under the Fostering Connections to Success Act and subsequent ACA provisions, former foster care youth who had Medicaid at age 18 or aged out of foster care are entitled to full Medicaid coverage until age 26, with no income test. This applies even if you move to a different state.
Can immigrants get Medicaid?
Lawfully present immigrants who meet income and residency requirements may qualify, but most must wait five years from their date of entry before becoming eligible for federally funded Medicaid — known as the five-year bar. Pregnant women, children, refugees, and asylees are among those exempt from the waiting period in many states. Undocumented immigrants are generally not eligible for full Medicaid benefits, though emergency Medicaid pays for emergency care in most states.
More on eligibility: the coverage gap
10 states have not adopted the ACA Medicaid expansion as of mid-2026. In those states — which include Texas, Florida, Georgia, and several others — working-age adults without dependent children often earn too much for traditional Medicaid but too little to receive Marketplace premium tax credits (which start at 100% FPL). Per KFF, this leaves roughly 1.2 million people in a coverage gap with no affordable options.
If you live in a non-expansion state, it is still worth applying. Pregnant women, parents of dependent children, people with disabilities, and adults over 65 have their own eligibility tracks that may apply even without expansion.
Coverage questions
What Medicaid pays for, limits, and coordination with other insurance.
What does Medicaid cover?
Federal law requires states to cover certain mandatory benefits: inpatient and outpatient hospital services, physician services, laboratory and X-ray services, nursing facility care, home health services, and EPSDT (Early and Periodic Screening, Diagnostic, and Treatment) for anyone under 21. States may add optional benefits such as prescription drugs, dental care for adults, vision, and physical therapy. Prescription drugs are technically optional but all states cover them.
Does Medicaid cover dental care for adults?
Dental coverage for adults is optional under federal law, so benefits vary widely by state. Some states offer comprehensive adult dental; others cover only emergency extractions. Children receive comprehensive dental under EPSDT regardless of state — that is a federal mandate. Per CMS data, roughly half of states provide limited or emergency-only adult dental benefits, while about a quarter offer more extensive coverage.
Does Medicaid cover nursing home care?
Yes — nursing facility services are a mandatory Medicaid benefit. Medicaid is the largest single payer for long-term care in the United States. To qualify for nursing home coverage, applicants must meet both a medical level-of-care requirement and financial eligibility tests. Asset limits apply; a single individual typically must spend down countable assets to around $2,000 before Medicaid pays. Married couples receive spousal protections that allow the community spouse to retain more assets.
Will Medicaid pay for services I received before I enrolled?
Possibly. Federal rules allow states to provide retroactive Medicaid coverage for the three calendar months before the month of application, provided you were eligible during that period. Not all states offer the full three months of retroactive coverage — some have requested and received waivers to limit it. If you had significant medical bills before enrolling, ask your state agency whether retroactive coverage applies to your situation.
Can I have Medicaid and private insurance at the same time?
Yes. Medicaid acts as the payer of last resort when you have other insurance — your private plan or employer coverage pays first, and Medicaid covers remaining cost-sharing or services not covered by the primary plan. You cannot receive premium tax credits on a Marketplace plan if you are already enrolled in full-benefit Medicaid; you must choose one. However, having employer-sponsored insurance does not automatically disqualify you from Medicaid if income-based eligibility is met.
A common misconception: Medicaid isn't comprehensive for everyone
People often assume that qualifying for Medicaid means full coverage for any health service. Not accurate. Benefits are divided into mandatory services that every state must cover and optional services that states may add or drop.
Dental coverage is the clearest example. Federal law does not require states to provide adult dental benefits at all. Under-21 enrollees get dental under EPSDT — that is federally guaranteed. Adults? Depends entirely on the state. Some states cover fillings, crowns, and dentures. Others pay only for emergency extractions. A handful provide nothing outside an emergency.
Vision, hearing aids, and non-emergency transportation are similarly optional. Check your state plan or ask your managed care plan directly what your specific benefits include.
Applying for Medicaid
Applications, timelines, denials, provider portals, and renewals.
How do I apply for Medicaid?
You can apply online through your state Medicaid agency's website or through healthcare.gov, by mail, in person at a local Medicaid office, or by phone. If you apply on healthcare.gov and appear eligible for Medicaid, the system forwards your information to your state automatically. There is no open enrollment window — you can apply any time of year.
How long does Medicaid approval take?
Federal regulations under 42 CFR 435.912 require states to process most Medicaid applications within 45 days. For applications based on disability, states have up to 90 days. In practice, many decisions come faster when documentation is complete. States that use automated eligibility verification can sometimes approve applications on the same day.
What happens if my Medicaid application is denied?
You have the right to appeal. States must provide written notice of any denial with a specific reason and instructions for requesting a fair hearing. You generally have 90 days from the denial notice to request a hearing, though deadlines vary by state. During the appeal, you can request to continue receiving any benefits you were already getting. A benefits counselor or legal aid organization can help you prepare your case.
How do I find a Medicaid provider or log in to my state Medicaid portal?
Each state operates its own Medicaid portal and provider directory. To find providers who accept Medicaid, visit your state agency's website or use the Medicaid provider portal search tool for your state. Most states have their portals listed on medicaid.gov. To log in to your Medicaid account (for checking coverage, updating information, or viewing claims), use the beneficiary portal specific to your state.
Do I have to renew my Medicaid coverage?
Yes. States are required to renew Medicaid eligibility at least once every 12 months. States must first attempt an "ex parte" renewal using existing data sources without requiring paperwork from you. If they cannot confirm eligibility automatically, you will receive a renewal packet to complete. Failing to respond to renewal notices is one of the most common reasons people lose Medicaid coverage — respond promptly and update your address with your state agency.
State Medicaid portals and provider lookups
Each state has its own Medicaid portal where beneficiaries can check enrollment status, update personal information, and view covered services. Providers use a separate Medicaid provider portal to submit claims, verify patient eligibility, and manage enrollment. The two portals are different systems — one for members, one for providers.
To find your state's beneficiary portal, go to medicaid.gov and navigate to your state's page. Most Medicaid member portals let you log in to confirm your coverage dates, change your managed care plan during open enrollment periods, and update your address. Keep your address current — renewal notices go to your address of record, and missing them is the leading cause of unnecessary coverage loss.
What changed in recent years
The post-pandemic Medicaid unwinding (April 2023 through December 2024) removed roughly 25 million people from Medicaid nationally, per CMS data released in early 2025. Most disenrollments were for procedural reasons — wrong address on file, paperwork not returned — not because people were actually ineligible. CMS issued a series of corrective guidance letters requiring states to fix process errors and restore coverage where warranted.
If you lost Medicaid coverage between 2023 and 2024 and believe it was a mistake, you can reapply. In many cases, people who were disenrolled for procedural reasons qualified again as soon as they reapplied.
The 2025 federal budget reconciliation law created a nationwide Medicaid work requirement — the first in the program's history — for most ACA expansion adults, taking effect no later than January 1, 2027 in the 43 expansion states plus DC. Unlike earlier state-by-state Section 1115 work-requirement waivers, this is enacted federal law that states cannot opt out of. Check your state agency's news section for implementation details and exemption criteria affecting your benefits.
Frequently confused terms
| Comparison | What differs |
|---|---|
| Medicaid vs. Medicare | Medicaid is income-based, for low-income people of any age, jointly funded by federal and state governments. Medicare is age-based (65+) or disability-based, federally run, with no income test. About 12 million people qualify for both — "dual eligibles," per KFF. |
| Medicaid vs. CHIP | CHIP covers children and pregnant women in families that earn too much for Medicaid but cannot afford private coverage. It's federally funded under Title XXI, separately from Medicaid. In many states, one application screens for both. |
| Managed care vs. fee-for-service | Most Medicaid enrollees are in managed care plans — contracted health plans paid a per-member monthly rate by the state. Fee-for-service Medicaid pays providers directly for each service. Both are Medicaid; only the delivery system differs. |
