Apply for Medicaid and unlock free or low-cost health coverage for your whole family.

Millions of Americans qualify and don’t even know it — missing out on benefits that could change everything.

Read on and find out exactly how to apply, who qualifies, and what you’ll get.

What Is Medicaid and Why Should You Apply for It?

Medicaid is a free or very low-cost health insurance program funded jointly by the federal government and each state, designed specifically for people with low to moderate income.

Unlike private insurance, Medicaid doesn’t require you to pay monthly premiums in most cases — and it covers a wide range of essential health services, from doctor visits and hospital care to prescription drugs and mental health treatment.

The program serves children, pregnant women, adults, seniors, and people with disabilities, making it one of the most far-reaching public assistance programs in the United States.

If you’ve been putting off getting health coverage because of cost, getting medical insurance through Medicaid might be the most practical and immediate solution available to you right now.

Who Qualifies to Apply for Medicaid?

Eligibility for Medicaid is primarily based on income and household size, though specific rules vary by state — which is why it’s essential to check your own state’s guidelines.

In general, you may qualify if you fall into one of the following categories:

Children under 19 in households with low to moderate income
Pregnant women who meet income requirements
Adults aged 19–64 with income at or below 138% of the federal poverty level (in states that expanded Medicaid under the Affordable Care Act)
Seniors aged 65 and older with limited income and resources
People with disabilities receiving Supplemental Security Income (SSI)
Families receiving TANF (Temporary Assistance for Needy Families)

Even if you currently work full-time, you might still qualify — Medicaid expansion has made coverage accessible to many working adults who previously had no affordable options.

If you already receive SNAP or TANF benefits, the process to apply for Medicaid is often faster, since your income eligibility has essentially already been verified by another program.

How to Apply for Medicaid: Step by Step

Applying for Medicaid is simpler than most people expect, and you have multiple options depending on your state and personal preference.

Here’s how to do it:

Check your eligibility first. Visit healthcare.gov or your state’s Medicaid website and use their eligibility screener tool. This gives you a quick, unofficial sense of whether you’re likely to qualify before you invest time in a full application.
Gather your documents. You’ll typically need proof of identity (driver’s license, passport, or state ID), proof of income (pay stubs, tax returns, or benefit award letters), proof of residency (utility bill or lease), and Social Security numbers for all household members applying.
Choose your application method. Most states allow you to apply online through their official Medicaid portal or through healthcare.gov. You can also apply by phone, by mail, or in person at your local Department of Social Services or Medicaid office.
Complete the application thoroughly. Provide accurate, complete information about every household member. Errors or missing details can delay your approval significantly.
Attend your interview if required. Some states require a brief interview — which can often be done over the phone — to confirm your information before making a final decision.
Wait for your determination letter. Most states process applications within 45 days. If you’re applying based on disability, it may take up to 90 days. In urgent situations, expedited processing is sometimes available.

Once approved, you’ll receive a Medicaid card and enrollment information for your specific managed care plan or coverage option.

Apply for Medicaid Online: The Fastest Way to Get Coverage

Applying online is the most convenient and often the fastest route to getting your Medicaid coverage started.

Through healthcare.gov, you can complete the entire application process from home, at any time that works for you.

This is especially valuable if you’re a working parent, a caregiver, or someone with limited transportation — you don’t need to take time off work or travel to a government office.

Several states have also developed their own streamlined online portals. If you want to apply for medical insurance online through your state directly, search for “[your state name] Medicaid application” and you’ll find the official portal quickly.

Keep in mind that applications through healthcare.gov during open enrollment also allow you to compare Marketplace plans alongside Medicaid — helpful if you end up not qualifying for Medicaid but still need coverage.

What Does Medicaid Cover?

Medicaid provides comprehensive health coverage that goes well beyond what many private plans offer at similar price points — in many cases, at zero cost to you.

Here’s what’s typically covered under most state Medicaid programs:

Doctor visits and preventive care (check-ups, screenings, vaccinations)
Hospital stays, both inpatient and outpatient
Emergency services and urgent care
Prescription medications
Mental health and substance use disorder treatment
Maternity and newborn care
Dental and vision care (coverage varies by state)
Home health services and long-term care for eligible seniors and people with disabilities
Lab tests and X-rays

States are required by federal law to cover certain “mandatory benefits,” and many choose to offer additional optional services on top of that.

If you’re pregnant, for example, Medicaid typically covers all prenatal visits, labor and delivery, and postpartum care — which is an enormous financial relief for families expecting a child.

Humana Medicaid and United Healthcare Medicaid: What You Should Know

In most states, Medicaid is delivered through private managed care organizations — meaning once you’re enrolled, you’re assigned to or choose a plan from an insurer that contracts with the state to provide your coverage.

Two of the most widely available Medicaid managed care plans in the country are Humana Medicaid and United Healthcare Medicaid (through the UnitedHealthcare Community Plan).

Here’s a quick comparison to help you understand your options:

Plan	Key Features	States Available
Humana Medicaid	Strong care coordination, robust member portal (MyHumana), telehealth access, focus on preventive care	Select states including FL, IL, KY, OH, TX, WI
United Healthcare Medicaid	Large provider network, community-based health programs, 24/7 nurse hotline, dual-eligible (Medicare + Medicaid) options	Over 30 states nationwide

If you complete a Humana Medicaid application or a United Healthcare Medicaid application, the process typically happens through your state’s Medicaid agency — not directly through the insurer.

Once the state approves your eligibility, you’ll select from the available managed care plans in your area, which may include Humana, United Healthcare, or other regional options.

Both plans offer online portals and mobile apps that make it easy to find in-network doctors, review your benefits, and manage your coverage after enrollment.

Fidelis Care and Covered California: Regional Medicaid Options Worth Knowing

Not all Medicaid managed care plans are national — some of the most well-rated options are regional programs that serve specific states with deep local expertise.

Fidelis Care is one of the largest Medicaid managed care plans in New York State, providing coverage to hundreds of thousands of low-income children, adults, seniors, and people with disabilities.

If you want to apply for Fidelis Medicaid coverage in New York, you do so through the state’s official health insurance marketplace or local Department of Social Services — not directly through Fidelis.

On the West Coast, Covered California is the state’s official health insurance marketplace, which works alongside Medi-Cal (California’s Medicaid program).

If you apply for Covered California and your income falls below Medi-Cal’s eligibility threshold, you’ll be automatically enrolled in Medi-Cal at no cost.

If your income is slightly above that threshold, you may qualify for subsidized private insurance through the Covered California marketplace instead — giving you coverage either way.

These regional programs often have strong local provider relationships and community health programs, so if you’re in New York or California, they’re worth understanding in detail as you navigate your sign up for medical insurance options.

What to Do If Your Application Is Denied

A denial isn’t the end of the road — in fact, many Medicaid applicants who are initially denied later receive coverage after submitting an appeal or correcting information on their application.

Here’s what to do if you receive a denial:

Read the denial letter carefully. It should explain the specific reason you were denied — whether it’s an income issue, missing documents, or a technical eligibility factor.
Request a fair hearing. You have the legal right to appeal any Medicaid decision. The deadline is typically 90 days from the date of the denial letter, so act promptly.
Correct errors and reapply. If the denial was due to missing or incorrect information, correcting it and resubmitting can often lead to approval.
Explore other coverage options. Even if you don’t qualify for Medicaid, you may be eligible for subsidized coverage through healthcare.gov — especially if your income falls in the range that qualifies for premium tax credits.
Contact a benefits navigator or enrollment assistant. These free services, available through community health centers and nonprofits, can help you understand your options and assist with the appeal process.

If you’re currently uninsured and were denied Medicaid, don’t give up — getting medical insurance coverage through another pathway is still very possible, and help is available.

Tips to Make Your Medicaid Application Go Smoothly

A little preparation before you start your application can save you significant time and reduce the chance of delays or requests for additional information.

Keep these practical tips in mind:

Apply as soon as possible — coverage can start as early as the first day of the month you apply, depending on your state.
Be completely honest about your income and household composition. Inaccurate information can result in denial, cancellation, or requests for repayment.
If your income fluctuates (freelance, seasonal, or gig work), report your expected annual income as accurately as possible.
Update your information promptly if anything changes — job status, household size, income, or address — to avoid losing coverage.
Keep copies of everything you submit and make note of any confirmation numbers or case IDs provided.
If applying for a child, the child must typically be present during in-person appointments or their information must be complete in online submissions.

Once you’re enrolled, take the time to actually use your coverage for preventive care — annual check-ups, vaccinations, and screenings that can catch problems early and save you money (and stress) down the line.
