This book presents the most complete up-to-date picture of the present status of voluntary health insurance in the United States. The contributors are authorities in every aspect of health insurance. The purpose of the book, as outlined by the chairman of the editorial advisory committee, is to make available a relatively complete story of the entire structure of voluntary health insurance in one book. This objective has been effectively achieved. A brief history of the development of voluntary health insurance is followed by a review of the nation's health record, the basic principles of health insurance, distribution of such insurance, the Blue Cross and Blue Shield movements, and other significant material. All physicians, whose professional future depends in large measure on the nature of developments in this changing field, should study this book and refer to it frequently as a source of authentic information.
