Medicaid for Seniors: Eligibility, Coverage, and How to Apply

What Is Medicaid and How Does It Differ From Medicare?

Medicaid is a joint federal and state health insurance program that provides coverage to people with limited income and resources, including millions of older adults. Although the federal government sets minimum standards, each state administers its own Medicaid program — meaning covered services, income limits, and application processes differ depending on where you live.

Medicare, by contrast, is a federal program available to nearly everyone age 65 or older regardless of income. The two programs are often confused, but they serve distinct roles. Medicare focuses on acute medical care — hospital stays, physician visits, prescription drugs — while Medicaid fills significant gaps, particularly for long-term services and supports. For a side-by-side look at enrollment in Medicare, see our guide to applying for Medicare.

For a broader overview of public programs available to older adults — including SNAP, LIHEAP, and housing assistance — refer to the Federal and State Benefits Programs reference guide.

Who Qualifies: Income, Assets, and Categorical Rules

Eligibility for Medicaid as a senior generally depends on three factors: categorical eligibility, income, and assets (called resources in Medicaid terminology).

• Categorical eligibility: You must belong to a covered group. Seniors age 65 or older who receive Supplemental Security Income (SSI) are automatically eligible in most states. Others may qualify through a state's aged, blind, and disabled (ABD) pathway. See how SSI compares to other disability-related benefits in our article on SSI versus Social Security Disability.
• Income limits: States set monthly income thresholds, often expressed as a percentage of the Federal Poverty Level (FPL). Some states use the SSI income standard; others have higher limits. Certain income sources — like the first $20 of most income — may be disregarded.
• Asset limits: Most states allow single applicants to retain a limited amount of countable assets, commonly around $2,000, though this varies. Married couples where only one spouse is applying for Medicaid have additional protections called spousal impoverishment rules, which allow the non-applicant spouse to retain a portion of the couple's assets.

Because rules vary widely by state and individual circumstances, this article provides general information only. Consult a licensed benefits counselor, elder-law attorney, or your state Medicaid office for guidance specific to your situation.

What Medicaid Covers for Older Adults

Federal law requires all state Medicaid programs to cover a core set of services, including inpatient and outpatient hospital care, physician services, laboratory and X-ray services, and nursing facility care for adults. States may also offer optional services such as:

• Prescription drugs (nearly all states cover these)
• Home health care and personal care services
• Adult day health services
• Dental, vision, and hearing services
• Mental health and substance use disorder treatment

One of Medicaid's most important benefits for older adults is coverage of long-term services and supports (LTSS) — including nursing home stays and home- and community-based services (HCBS) — that Medicare covers only in limited circumstances. If you or a family member is managing a chronic condition that may require ongoing care, the Managing Chronic Conditions hub offers additional context on long-term care planning.

How to Apply for Medicaid

Applications are submitted to your state Medicaid agency, not to the federal government. You can typically apply online through your state's benefits portal, in person at a local Department of Social Services office, or by mail. Here is a general overview of the process:

1. Gather documents: You will typically need proof of identity (such as a passport or driver's license), proof of age, proof of state residency, Social Security number, recent bank statements, proof of income (Social Security award letters, pension statements), and documentation of any real property or vehicles.
2. Complete the application: Answer all questions accurately. Incomplete applications cause delays.
3. Attend an interview, if required: Some states require an in-person or telephone interview as part of the application process.
4. Receive a determination: States must generally decide standard applications within 45 days. You will receive a written notice of approval or denial.
5. Appeal if denied: You have the right to request a fair hearing if your application is denied or you disagree with the benefit amount.

Free help is available. State Health Insurance Assistance Programs (SHIPs) provide one-on-one counseling at no cost. Your local Area Agency on Aging can also connect you with benefits navigators. Use our Annual Benefits Review Checklist to stay on top of eligibility each year.

Medicaid and Long-Term Care: What Seniors Should Know

For many seniors, the most consequential aspect of Medicaid is its role in financing long-term care. A nursing home stay can cost tens of thousands of dollars per year, and Medicare's nursing facility benefit is limited to short-term skilled care following a qualifying hospital stay. Medicaid steps in for individuals who meet financial eligibility requirements and require ongoing custodial care.

Spend-down: Some states allow individuals whose income exceeds the standard limit to become eligible by deducting qualifying medical expenses — a process known as a spend-down or medically needy pathway.

Estate recovery: Federal law requires states to seek reimbursement from the estates of deceased Medicaid beneficiaries who were 55 or older when they received certain services. Protections exist for surviving spouses and dependent children. An elder-law attorney can explain the implications for your estate plan.

Home- and community-based waivers: Many states operate Medicaid waiver programs that allow eligible seniors to receive care at home or in assisted living instead of a nursing facility. Waiting lists exist in some states, so early inquiry is advisable.
