A single-payer system is a type of healthcare system where a single public or government entity manages the financing of healthcare services. In this model, the government collects taxes to fund healthcare and pays for medical services directly, eliminating the need for private health insurance companies. This approach aims to provide universal coverage for all citizens, ensuring that everyone has access to necessary medical care. In a single-payer system, patients typically do not receive bills for medical services, as costs are covered by the government. This can simplify the healthcare process, reduce administrative costs, and potentially lead to lower overall healthcare spending. Countries like Canada and the United Kingdom have implemented variations of this system, demonstrating its potential benefits and challenges.
