Which program is jointly administered by federal and state governments?

Medicaid is a program that is jointly administered by federal and state governments, making it unique among the options listed. It was established to provide healthcare coverage to low-income individuals and families, and its funding and administrative responsibilities are shared between both levels of government. Each state has the flexibility to design its own Medicaid program within federal guidelines, which means that eligibility requirements, benefits, and payment structures can vary significantly from one state to another.

In contrast, Medicare is solely a federal program that provides health coverage primarily for individuals aged 65 and older, as well as some younger people with disabilities. The Children’s Health Insurance Program (CHIP) is also a federal-state partnership but is considered a separate program from Medicaid. Private insurance, on the other hand, is not a public program and is instead offered by private companies without direct federal or state government administration.
