That really depends on where the veteran is. If they are in the Paris area, they can easily go to a military hospital. There are not many military hospitals these days. If I remember correctly, there may be 10 or so, eight or nine, I think. They are basically in the large French cities. However, veterans can have access to a Centre médical des Armées, meaning that every military unit has a medical centre nearby with a few doctors, and veterans can knock on that door.
