Invalid restrictive covenants.

A restrictive covenant entered into with a physician who is licensed under chapter 458 or chapter 459 and who practices a medical specialty in a county wherein one entity employs or contracts with, either directly or through related or affiliated entities, all physicians who practice such specialty in that county is not supported by a legitimate business interest. The Legislature finds that such covenants restrict patient access to physicians, increase costs, and are void and unenforceable under current law. Such restrictive covenants shall remain void and unenforceable for 3 years after the date on which a second entity that employs or contracts with, either directly or through related or affiliated entities, one or more physicians who practice such specialty begins offering such specialty services in that county.
