The purpose of this legislation is to extend the Rural Community Hospital Demonstration Program, which aims to support healthcare services in rural areas of the United States. The program is designed to ensure that rural hospitals can continue to provide essential medical services to their communities. The key provision of this law is the extension of the demonstration program from a previous 15-year period to a new 20-year period. This means that rural community hospitals will have additional time to participate in the program and receive support.
