The purpose of this legislation is to create a pilot program that allows pregnancy to be recognized as a qualifying event for enrollment in TRICARE Select, which is a health care program for military families. This change aims to provide better access to health care for pregnant service members and their dependents. Key provisions of the legislation include the establishment of a five-year pilot program that must begin within 180 days of the law being enacted. The Secretary of Defense is tasked with implementing this program.
