I had a few docs in class recently that have told me anyone turning 65 after April 1st will be turned away from the base hospital and be told to use Tri-Care for Life on the local economy. Anyone 65 before that day will be able to continue healthcare on the installation for now.
If you turn 65 this year and use a local installation for your healthcare you may want to ask about this where you get care? The Army is projecting 7,000 healthcare provider cuts.
