Which organization issues regulations and guidelines for healthcare organizations?

The Centers for Medicare and Medicaid Services (CMS) is the correct choice because it plays a vital role in regulating healthcare organizations in the United States. CMS oversees Medicare and Medicaid programs, ensuring that healthcare facilities comply with federal standards and guidelines. This includes establishing regulations concerning how care is delivered, reimbursement processes, patient rights, and quality of care. By setting these standards, CMS directly impacts healthcare policies, administrative procedures, and overall healthcare quality across the country.

The other organizations serve specific roles, but they do not primarily issue regulations for healthcare organizations in the same comprehensive manner as CMS. The World Health Organization (WHO) focuses on international public health, providing guidance and developing health policies on a global scale. The American Medical Association (AMA) is a professional association that primarily advocates for physicians and medical practices, contributing to medical ethics and education rather than direct regulatory oversight. The National Institutes of Health (NIH) is involved in medical research and funding rather than regulatory activities, focusing on improving health through research rather than controlling healthcare organizations.
