Healthcare payment options have become enormously complex. All providers are subject to different types of payment systems, each of which has its own variations. Making sense of the revenue cycle requires a full understanding of the payment system in use as well as the specific requirements of a third-party payer using a particular payment system. This book provides a complete introduction to healthcare payment systems. The text presents key concepts, terminology, and approaches for payment processes. Such concepts are used by providers for developing and filing claims and third-party payers and insurance companies for adjudicating and paying for healthcare services.
