On Jan. 1, 2018, TRICARE Select will replace TRICARE Standard and TRICARE Extra. As a result, beneficiaries will notice improved coverage for preventive services with TRICARE Select. This type of health care allows you to address health problems before they become life threatening. Examples of TRICARE-covered preventive services include cancer screenings and vaccines, in addition to well-woman and well-child exams. A new preventive service added this year for both TRICARE Prime and TRICARE Select is aimed at adults with a Body Mass Index (BMI) of 30 kg/m2 or higher.
