How to Apply for Medicaid in 2026: Complete Step-by-Step Guide

Applying for Medicaid can feel overwhelming, but the process is more straightforward than most people expect. This guide walks you through every step — from checking your eligibility to submitting your application and following up — so you can get health coverage as quickly as possible.

Medicaid is available year-round, meaning there is no open enrollment window. If you qualify today, you can apply today. And if you are approved, coverage may even apply retroactively to medical bills you already received.

What Is Medicaid?

Medicaid is a joint federal and state health insurance program that provides free or low-cost coverage to eligible low-income individuals and families. It is administered by individual states within federal guidelines set by the Centers for Medicare & Medicaid Services (CMS).

Unlike Medicare, which is primarily age-based, Medicaid is income-based. Coverage varies by state but typically includes doctor visits, hospital stays, emergency care, prescription drugs, mental health services, and long-term care. Some states also cover dental and vision services for adults.

As of 2026, Medicaid covers approximately 80 million Americans, making it the largest source of health coverage in the United States. (Source: medicaid.gov)

Who Qualifies for Medicaid in 2026?

Eligibility depends on your state, household size, income, age, and other factors. Here is a breakdown of the main eligibility categories.

Income Eligibility: The Federal Poverty Level (FPL)

Most Medicaid eligibility is calculated using Modified Adjusted Gross Income (MAGI), which is based on your household’s total gross income before most deductions. Eligibility thresholds are set as a percentage of the Federal Poverty Level (FPL).

The 2026 FPL for a family of four is approximately $31,800 per year (Source: aspe.hhs.gov, accessed June 2026). States set Medicaid income limits as a percentage of this figure.

See our detailed Medicaid income limits by state for 2026 for exact thresholds in your state.

Medicaid Expansion States (40 States + DC)

Under the Affordable Care Act (ACA), states that adopted Medicaid expansion cover adults ages 19–64 with incomes up to 138% of the FPL. For a family of four, that is approximately $43,884 per year in 2026. Single adults qualify with income up to roughly $20,783 per year.

As of 2026, 40 states and the District of Columbia have expanded Medicaid. If you live in one of these states and your income falls below 138% FPL, you are very likely to qualify as an adult — regardless of whether you have children.

Non-Expansion States (10 States)

In the 10 states that have not expanded Medicaid, adult eligibility is generally more limited. Adults in these states typically must fall into one of the following categories to qualify:

• Parent or caretaker relative of a dependent child
• Pregnant woman
• Person with a disability (as determined by SSI/SSDI standards)
• Adult age 65 or older

Income limits in non-expansion states for parents are often below 100% FPL and vary significantly by state. Working-age adults without children generally do not qualify for Medicaid in non-expansion states unless they are disabled.

Special Eligibility Groups

• Children: Children are eligible through Medicaid or the Children’s Health Insurance Program (CHIP) at income levels typically between 133% and 300% FPL or higher, depending on the state.
• Pregnant women: Most states cover pregnant women at income levels above standard adult thresholds — often at 138% to 200% FPL or higher. Coverage typically extends 12 months postpartum.
• Elderly adults (65+): Seniors may qualify for Medicaid to supplement Medicare, particularly for long-term care services and nursing home coverage. Income and asset limits apply.
• People with disabilities: Individuals who receive Supplemental Security Income (SSI) are generally automatically enrolled in Medicaid in most states. Others with disabilities may qualify through a separate income and asset review.

You may also qualify for multiple programs at once. See our guide to government assistance programs in 2026 for a complete picture of overlapping benefits.

4 Ways to Apply for Medicaid

You can apply for Medicaid through four official channels. All lead to the same eligibility determination — choose whichever is most convenient for you.

1. Online via HealthCare.gov

In most states, you can start a Medicaid application at healthcare.gov. When you fill out a Marketplace application and your income falls below the Medicaid threshold, the system automatically routes your application to your state Medicaid agency. This is the most common starting point for most applicants.

2. Through Your State’s Medicaid Portal

Every state operates its own Medicaid agency website with a dedicated application portal. In some states (called “state-based exchanges”), you cannot use healthcare.gov and must apply directly through the state site. Examples include Covered California, NY State of Health, and Washington Healthplanfinder. Search “[your state] Medicaid application” to find your state’s portal.

3. By Phone

Call the federal Marketplace at 1-800-318-2596 (TTY: 1-855-889-4325), available 24 hours a day, 7 days a week. Representatives can help you apply for Medicaid or transfer your application to your state agency. Alternatively, call your state Medicaid office directly — phone numbers are listed at medicaid.gov.

4. In Person

You can apply in person at your local Medicaid office, community health center, or social services office. Some areas also have certified application assistors and navigators who can help you complete the form at no cost. Find local help at localhelp.healthcare.gov.

Step-by-Step Application Process

Step 1: Check Whether Your State Expanded Medicaid

Before doing anything else, find out whether you live in a Medicaid expansion state. This single factor determines whether you — as an adult without children or a disability — can qualify at all. CMS maintains a current list at medicaid.gov.

Step 2: Gather Required Documents

Before you begin your application, collect the documents listed in the “Documents You Need” section below. Having these on hand will prevent delays and avoid a mid-application stop.

Step 3: Choose Your Application Method

Select one of the four methods described above. Online via healthcare.gov or your state portal is typically the fastest. If you need language assistance or have complex circumstances, calling or going in person may be easier.

Step 4: Complete the Application

The application will ask about every member of your household — not just those seeking coverage. You will need to provide income information, household composition, citizenship or immigration status, and whether you have other health coverage. Answer every question accurately. Providing false information to obtain Medicaid is a federal offense.

Step 5: Submit and Track Your Application

After submitting, save or print your confirmation number. Most online portals allow you to check application status. Your state Medicaid agency may contact you for additional documentation — respond promptly to avoid delays. Federal law requires states to process most applications within 45 days (or 90 days for applications based on disability). (Source: 42 CFR §435.912, CMS)

Documents You Need

The exact list varies by state, but you should expect to provide the following. Gather these before you start to avoid delays.

• Proof of identity: Driver’s license, state ID, passport, or birth certificate
• Proof of residency: Utility bill, lease agreement, or bank statement with your current address
• Social Security Numbers: For yourself and all household members applying for coverage
• Proof of income: Recent pay stubs (last 30 days), employer letter, or most recent tax return; self-employment records if applicable
• Immigration documents (if applicable): Green card, visa, or immigration status document for non-citizens
• Insurance information: If you or a household member currently has health coverage, have the policy details available
• Bank statements or asset documentation: Required mainly for elderly or disabled applicants; not required in most MAGI-based adult applications
• Disability documentation: SSI/SSDI award letters or medical records if applying on the basis of disability

Some states have simplified verification procedures and may accept a self-attestation for income or residency initially. If your state cannot verify a document electronically, they will mail you a request — respond within the time window specified or your application will be delayed.

What Happens After You Apply

Processing Timeline

Federal regulations require states to determine Medicaid eligibility within these timeframes after you submit a complete application:

• Standard applications: 45 calendar days
• Disability-based applications: 90 calendar days

Many states process applications faster — sometimes within days for online submissions that can be verified electronically. If you have not heard back within the required window, contact your state Medicaid office directly.

Presumptive Eligibility

Some states allow “presumptive eligibility,” which means a qualified entity (such as a hospital or community health center) can temporarily enroll you in Medicaid while your full application is being reviewed. This provides immediate coverage so you can get care without waiting. Ask your hospital or health center whether your state offers this option.

Retroactive Coverage

If approved, Medicaid coverage can be applied retroactively to cover medical expenses incurred up to three months before the month you applied — as long as you were eligible during those months. This means if you had a medical emergency in the months before you applied, Medicaid may still pay those bills. Always ask your state agency about retroactive coverage when you submit your application.

Renewal

Medicaid coverage is not permanent. You must renew your eligibility annually (called “redetermination”). Your state will send a notice before your renewal date — review it carefully and respond to any information requests to avoid losing coverage. Many states now use automated renewals based on data from other state systems, so the process is often simpler than the initial application.

Medicaid Expansion vs. Non-Expansion States

The ACA gave states the option to expand Medicaid starting in 2014. As of 2026, 40 states and DC have expanded; 10 have not. This distinction matters enormously if you are a working-age adult without dependent children.

Note: State expansion status can change. Always confirm your state’s current status at KFF.org or medicaid.gov for the most up-to-date information.

If you live in a non-expansion state and do not qualify for Medicaid, you may still qualify for reduced-cost Marketplace coverage. See our guide to free and low-cost government healthcare options for alternatives. You may also benefit from reviewing our SNAP food stamps eligibility guide or other assistance programs.

What to Do If You Are Denied

A denial is not the end of the road. You have legal rights to appeal any Medicaid decision.

Common Reasons for Denial

• Income exceeded the state’s eligibility threshold
• Missing or unverifiable documentation
• Residency could not be confirmed
• Citizenship or immigration status issue
• Already enrolled in another disqualifying health program
• Application was incomplete or contained errors

Your Right to a Fair Hearing

Federal law guarantees you the right to appeal a Medicaid denial or termination through a “fair hearing” — an administrative review process. You must request a hearing within the deadline stated on your denial notice, which is typically 90 days from the date of the notice. (Source: medicaid.gov — Appeals and Grievances)

How to Appeal

1. Read your denial notice carefully — it must explain the specific reason for denial and your appeal rights.
2. Gather documentation that addresses the denial reason (for example, corrected income records or proof of residency).
3. Request a fair hearing in writing by the deadline shown on the notice. Send by certified mail and keep a copy for your records.
4. If you were already enrolled and your coverage is being terminated, you may be able to continue benefits during the appeal by requesting “aid pending appeal.”
5. At the hearing, present your case and any supporting documents. You may bring an advocate, legal aid attorney, or other representative.

You may also contact your state Medicaid office directly to correct a simple documentation error, which can sometimes resolve a denial without a formal hearing.

Common Mistakes to Avoid

• Not reporting all household income: Medicaid looks at total household MAGI, including income from all members. Underreporting can result in denial or repayment demands later.
• Only applying for yourself when your children may also qualify: Even if you do not qualify as an adult, your children may be eligible for Medicaid or CHIP at a higher income threshold. Apply for them as part of the same application.
• Missing documentation requests: If your state requests additional documents and you do not respond in time, your application will be denied. Watch your mail and email after applying and respond promptly.
• Assuming you do not qualify without checking: Eligibility rules are complex and change over time. Use an official screener or speak to a navigator before assuming you are ineligible.
• Not asking about retroactive coverage: If you had medical bills in the past three months, retroactive coverage may cover them. Always ask when you apply.
• Forgetting to renew: Many people lose Medicaid not because they stopped qualifying, but because they missed their annual renewal notice. Set a calendar reminder each year around your renewal date.
• Using unofficial third-party websites: Apply only through official government portals (healthcare.gov or your state’s .gov Medicaid site). Unofficial “enrollment” sites may charge fees or misuse your personal information.

Frequently Asked Questions

Can I apply for Medicaid at any time of year?

Yes. Unlike Marketplace health insurance plans, Medicaid has no open enrollment period. You can apply on any day of the year. If you qualify, your coverage can begin as soon as the first day of the month in which you applied — or even retroactively for up to three prior months if you met eligibility requirements during that period.

How long does Medicaid approval take?

Federal law requires states to process standard Medicaid applications within 45 calendar days and disability-based applications within 90 calendar days of receiving a complete application. Many states process online applications significantly faster — sometimes within a few days — when income and identity can be verified electronically through existing government data systems. If your application requires manual review or additional documents, processing may take longer, up to the federal maximum.

Can I have Medicaid and employer-sponsored insurance at the same time?

Yes. This is called dual coverage. When you have both, your employer plan acts as primary insurance and pays first. Medicaid typically acts as secondary and may cover remaining out-of-pocket costs such as co-pays, deductibles, or services your employer plan does not cover. You are required to report any other health coverage when you apply for or renew Medicaid.

What is the income limit for Medicaid?

Income limits vary by state, household size, and age. In the 40 expansion states and DC, most adults qualify with income up to 138% of the FPL — approximately $20,783 per year for a single adult or $43,884 for a family of four based on 2026 FPL guidelines. Non-expansion states have lower and more restricted thresholds that apply only to specific categories. See our state-by-state Medicaid income limit guide for exact figures. (Source: aspe.hhs.gov, 2026 FPL guidelines)

Does Medicaid cover dental and vision?

Coverage varies by state. Federal law requires Medicaid to cover dental and vision for children under 21 through the Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) benefit. For adults, dental and vision coverage is optional under federal rules, so it depends entirely on your state. Some states provide comprehensive adult dental benefits; others offer emergency dental only or no routine adult dental coverage. Check your state Medicaid agency’s website for the specific benefits offered to adults in your state.

Can immigrants apply for Medicaid?

Eligibility depends on immigration status and length of U.S. residence. Lawful Permanent Residents (green card holders) who have lived in the U.S. for five or more years are generally eligible for full Medicaid. Refugees, asylees, and certain other humanitarian immigration statuses may qualify immediately without a waiting period. Undocumented immigrants are generally not eligible for full Medicaid but many states provide emergency Medicaid for urgent medical conditions. Children and pregnant women may have expanded access through some state programs. Consult a benefits counselor or immigration attorney for guidance on your specific situation. (Source: medicaid.gov — Immigration Status)

What is the difference between Medicaid and Medicare?

Medicare is a federal health insurance program primarily for people age 65 and older, and for certain younger people with qualifying disabilities or end-stage renal disease. Eligibility is not based on income. Medicaid is a joint federal-state program for low-income individuals and families of any age, and eligibility is income-based. Some people qualify for both programs simultaneously — called “dual eligibles” — which can provide very comprehensive combined coverage. See our guide to government healthcare programs for a detailed comparison of Medicare, Medicaid, CHIP, and Marketplace coverage.

Can I apply for Medicaid for my children even if I do not qualify myself?

Yes, absolutely. Children’s Medicaid and CHIP eligibility is determined separately from adult eligibility and at higher income thresholds. Even if your income is too high for adult Medicaid, your children may qualify for Medicaid or the Children’s Health Insurance Program (CHIP). In most states, children in families earning up to 200%–300% of the FPL can receive coverage through CHIP. The application process for children is the same as for adults — simply include them on your application. There is no penalty for applying. Also check our guide to cash assistance programs for additional family benefit options you may be eligible for.
