Understanding Medicaid Eligibility

Each state has its own set of eligibility criteria for Medicaid, but all of them must comply with federal guidelines. Generally, eligibility is determined by a combination of factors, including income level, household size, and your health situation.

Income Eligibility

Income is the primary factor in determining Medicaid eligibility. Your income must fall below a certain threshold, which varies by state and is based on the Federal Poverty Level (FPL). In most states, eligibility for adults typically ranges from 100% to 138% of the FPL, while children, pregnant women, and seniors may have higher thresholds.

Category Eligibility

Medicaid is designed to assist certain categories of individuals, including:

  • Low-income children and their parents or caretakers
  • Pregnant women
  • Individuals with disabilities
  • Seniors aged 65 years or older

Non-financial Eligibility

Other factors that can affect your eligibility for Medicaid include your citizenship status and residency. Generally, Medicaid is only available to U.S. citizens, certain qualified non-citizens, and legal permanent residents. Additionally, recipients must be residents of the state in which they apply for Medicaid.

Medicaid Benefits and Services

Medicaid provides a wide range of healthcare services, with some variation based on the state where you live. Federal law mandates that every state’s Medicaid program must offer a set of mandatory benefits, while it may also provide additional optional benefits.

Mandatory Benefits

These are the health services that every state Medicaid program is required to provide:

  • Inpatient and outpatient hospital services
  • Nursing home care
  • Home health care
  • Doctor and clinic services
  • Laboratory and X-ray services
  • Family planning services and supplies
  • Transportation to medical appointments

Optional Benefits

States have the option to provide these additional services to Medicaid recipients:

  • Prescription drug coverage
  • Dental and vision care
  • Physical and occupational therapy
  • Speech, hearing and language disorder services
  • Chiropractic services
  • Podiatry services
  • Respite and hospice care

Applying for Medicaid

There are multiple ways to apply for Medicaid, and the fastest method is usually to apply online. Paper applications are also available for those who prefer this method.

Online Application

Online applications can be submitted through the Health Insurance Marketplace website at www.healthcare.gov or through your state’s Medicaid agency website.

Phone Application

You can also apply for Medicaid by phone. Contact your state’s Medicaid office or call the Health Insurance Marketplace at 1-800-318-2596 for assistance.

Paper Application

If you prefer to apply using a paper application, you can download and print one from your state’s Medicaid agency website or visit a local office to obtain an application form.

Required Documentation

When applying for Medicaid, you will need to provide various documents to verify your eligibility. While specific requirements may vary between states, some common documents include:

  • Proof of income (e.g., paystubs, W-2 forms)
  • Proof of citizenship or immigration status
  • Proof of residency (e.g., utility bill, lease)
  • Identification (e.g., driver’s license, passport)
  • Social Security number

How States Administer Medicaid

While Medicaid is a federal program, each state designs and operates its own program within federally established guidelines. As a result, Medicaid programs can vary significantly between states, with differences in eligibility criteria, benefits offered, and provider networks.

State Plan Amendments

States submit their proposed Medicaid programs to the Centers for Medicare & Medicaid Services (CMS) as State Plan Amendments (SPAs). These SPAs outline the specific policies and procedures that each state will follow, and CMS must approve them before implementation.

Managed Care Organizations

Many states use Managed Care Organizations (MCOs) to provide healthcare services to Medicaid beneficiaries. These MCOs contract with healthcare providers and hospitals to create networks, manage care, and control costs. Beneficiaries generally select a primary care provider within their MCO’s network and may need referrals for specialty care services.


In some states, Medicaid operates under a fee-for-service (FFS) model. Under this system, healthcare providers are paid directly for each service provided to Medicaid beneficiaries. Unlike with MCOs, beneficiaries in FFS programs do not need to select a primary care provider and generally have greater flexibility in choosing their providers.

The Impact of the Affordable Care Act on Medicaid

The Affordable Care Act (ACA) enacted several important changes to the Medicaid program, most notably the expansion of eligibility to more low-income individuals and families.

Medicaid Expansion

Under the ACA, states have the option to expand Medicaid coverage to individuals with incomes up to 138% of the Federal Poverty Level. This expansion has allowed millions of additional low-income adults to access healthcare services through Medicaid. As of 2021, 38 states (including the District of Columbia) have adopted Medicaid expansion, while 12 states have not.

Simplified Eligibility and Enrollment

The ACA also streamlined the application process for Medicaid, making it easier for individuals and families to sign up for coverage. Health Insurance Marketplace websites serve as a “one-stop-shop” for applying for both Medicaid and private insurance subsidies, enabling applicants to receive an eligibility determination for all available programs through a single application.

Enhanced Funding

The federal government provides significant financial support to states actively implementing Medicaid expansion, covering 90% of the costs associated with newly eligible beneficiaries. This increased funding has allowed states to expand their Medicaid programs without straining their budgets.

Improved Benefit Standards

The ACA established Essential Health Benefits (EHB), a set of ten categories of healthcare services that all health insurance plans, including Medicaid, must cover. Some of these categories include mental health and substance use disorder services, prescription drug coverage, and maternity and newborn care. As a result, Medicaid beneficiaries in states that have adopted the expansion now have access to a broader range of healthcare services.

In conclusion, Medicaid serves as a crucial safety net, providing millions of low-income individuals and families across the United States with access to essential healthcare services. Despite the complexities and variations in state programs, understanding the basics of Medicaid eligibility, benefits, and application processes can empower you to make informed decisions about your healthcare options. The Affordable Care Act has significantly impacted Medicaid, expanding coverage to millions of additional individuals and improving the quality of services offered. Whether you are currently eligible for Medicaid or not, staying informed of the program’s development and changes can prepare you for any future healthcare needs.
