Health Care Funding

I’m trying to learn for my Health & Medical class and I’m stuck. Can you help?

As we know, the United States Healthcare System is complex and there is no one entity that funds the services provided to patients. We have one of the most technologically advanced health care systems, but it is also one of the most expensive. Please answer the following questions in an APA formatted paper of no less than 2 pages:

1. What are the differences in insurance plan funding between Medicare (Part A, B, C, D), Medicaid, and Private Insurance plans?
2. Are there any current and/or future healthcare funding concerns for Medicare, Medicaid, and Private Insurance plans?
3. What are the general differences between funding a Single Payer Model (for example, Canada’s Healthcare Model) of healthcare compared to Private Insurance plan model in the United States?
4. What are your thoughts and ideas on how to fix the US healthcare model raising costs and funding models. Should the US adopt a single payer model healthcare system? Why or why not? Be specific in your reasoning, thoughts, and ideas.
