What is the US healthcare system?
The US healthcare system is a network of healthcare providers, insurance companies, government programs, and patients that work together to deliver medical care. It includes hospitals, physician offices, clinics, pharmacies, laboratories, and health insurance plans that help pay for healthcare services.

The main stakeholders are patients, healthcare providers, insurance companies (payers), employers, and government agencies such as the Centers for Medicare & Medicaid Services (CMS). Each stakeholder plays a different role in delivering, regulating, financing, or receiving healthcare services.
