What does the CMS oversee regarding healthcare programs?

The Centers for Medicare & Medicaid Services (CMS) is primarily responsible for administering federal healthcare programs, which include Medicare, Medicaid, the Children's Health Insurance Program (CHIP), and some aspects of the Affordable Care Act (ACA). This role involves overseeing the implementation, management, and funding of these programs. CMS ensures that these programs provide quality healthcare services to eligible individuals and manages the associated regulations and payment systems. By focusing on this administrative function, CMS plays a crucial role in shaping healthcare access for millions of Americans.

The other options do not accurately reflect the main responsibilities of CMS. For instance, setting marketing strategies relates more to business operations and branding, which is outside CMS’s purview. Building healthcare infrastructure typically falls under the domain of government agencies focused on public health and urban development, rather than a specific program like those managed by CMS. Conducting research on medical devices is often the role of organizations like the Food and Drug Administration (FDA) or research institutions rather than an administrative body like CMS, which focuses on program administration rather than research or product development.
