Oversees Medicare, Medicaid, public health, and biomedical research — once combined with what is now a separate Department of Education.

HHS runs the federal government’s major health and human-services programs: Medicare and Medicaid, the CDC’s public health work, FDA food and drug safety, NIH biomedical research, and family and child welfare programs. Most people encounter it through Medicare, a food or drug recall, or CDC health guidance.

HHS is the United States government’s principal agency for protecting the health of all Americans and providing essential human services.

What It Does

HHS was created in 1953 as the Department of Health, Education, and Welfare (HEW) — a single department covering health, education, and social-welfare programs together. Congress split education into its own Cabinet department in 1979, and the remaining department was renamed Health and Human Services.

Administers Medicare and Medicaid

CMS runs the federal health insurance programs covering seniors, people with disabilities, and low-income Americans.

Medicare and Medicaid

Tracks public health

The CDC monitors disease outbreaks, issues health guidance, and runs vaccination and prevention programs.

Public health guidance

Regulates food and drug safety

The FDA approves drugs and medical devices and sets food safety standards.

Food and drug safety

Funds biomedical research

NIH funds and conducts medical research across nearly every disease area.

How It Fits Into Government

Chain of accountability

Split into two departments in 1979

HEW combined health, education, and welfare programs under one Secretary from 1953 to 1979, when Congress created a separate Department of Education and renamed the remainder Health and Human Services. Congress writes the statutes governing Medicare, Medicaid, and FDA authority, and funds HHS’s budget — the largest of any Cabinet department, driven mostly by Medicare and Medicaid spending.

Worth knowing

HHS used to include education

A common misconception is that health and education have always been separate federal concerns. From 1953 to 1979, they were run by the same department — the Department of Health, Education, and Welfare. Congress split education into its own Cabinet department in 1979, the same kind of division that separated Commerce from Labor decades earlier, leaving HHS focused on health and social-welfare programs alone.
