This concise but thorough handbook intended for the consumer, presents all of the most essential aspects of the American healthcare systems, services and products. It is updated and published annually, sometimes during the year, in order to incorporate any recent changes or perspectives. This being a midyear 2021 updated revised and corrected version. It is drawn from public sources and knowledge, both governmental and industry, to create an approachable and understandable overview. It is not intended as an in-depth academic work. I hope this handbook shows you the path in your healthcare journey, through illness or enlightenment.
