What does CMS stand for?

The correct term for CMS is "Centers for Medicare and Medicaid Services." This agency is a part of the U.S. Department of Health and Human Services and is responsible for administering the nation’s major healthcare programs including Medicare and Medicaid. By overseeing these programs, CMS plays a vital role in the healthcare system, as it establishes regulations and guidelines that help ensure the quality and accessibility of medical care for millions of Americans.

The other options presented do not accurately reflect the agency's official name: one option suggests a narrower focus on Medicaid without acknowledging Medicare, while another implies a focus on medical studies which is not relevant to CMS's role. Therefore, understanding CMS as "Centers for Medicare and Medicaid Services" is crucial for anyone studying healthcare policy and administration.
