Similar, but Distinct Programs

Federal programs that support income security and health are often mistakenly characterized interchangeably. From television pundits to average citizens, we often hear someone refer to Medicaid when they mean Medicare; Supplemental Security Income benefits are often confused with Social Security benefits. The programs, although similarly named, are distinct in terms of purpose, financing and specific populations served.

There is also a popular belief that individuals in this country illegally are eligible for these programs. In fact, undocumented persons cannot qualify for any of these benefits. In order to qualify for benefits, individuals must be legally present in the U.S., plus have either a significant connection to the workforce or military service. The following chart serves as a guide to the differences in these programs.

Program Funding Source Eligibility Requirements Number of Beneficiaries
Social Security Self-financed via FICA taxes Workers, who are insured for SS benefits and have attained age 62 or are disabled, and their dependents 65 million
Supplemental Security Income General Revenues Individuals who are aged, blind or disabled with little or no income or resources 7.8 million
Medicare Part A-Self-financed via FICA taxes

Part B and Part D- Monthly premiums and general revenues

Workers (including their dependents), who are insured for SS benefits, and have attained age 65 or received Social Security disability benefits for at least 2 years 61 million
Medicaid General Revenues Adults and children with little or no income or resources; requirements vary by state 76 million

 

Social Security pays monthly benefits to older workers who have paid sufficient Federal Insurance Contribution Act (FICA) taxes to be insured for benefits. Workers must have attained aged 62. The program also pays benefits to workers’ dependents or survivors. Workers who become disabled before retirement age are eligible for benefits as well. There are currently 64 million beneficiaries receiving Social Security, most of whom are elderly.

Medicare offers health insurance to older workers who are insured for Social Security benefits and have attained age 65 and to disabled beneficiaries who have been receiving Social Security disability benefits for at least two years. Dependents and survivors over age 65 also receive health insurance under Medicare. Part A of Medicare, which covers hospital insurance, is financed through workers’ FICA taxes. Part B, which covers physician’s payments, and Part D, which provides prescription drug coverage, are financed through monthly premiums paid by beneficiaries and general revenues. Medicare serves a predominately elderly population of 53 million in addition to 9 million younger beneficiaries who receive Social Security disability benefits.

Supplemental Security Income (SSI) provides a monthly income to low-income aged, blind or disabled individuals, and disabled children. Recipients must meet strict income and resource limits. The program is financed by general tax revenues. Approximately 7.8 million people receive SSI benefits.

Medicaid provides health insurance and long-term services and supports to low-income individuals. These programs are designed for a population with little or no income or resources and are financed through general revenues (federal taxes). Eligibility requirements vary by state with regard to age, marital status, etc. Medicaid provides services to about 76 adults and children.
