(2) Is “permanently housebound” by reason of disability or disabilities. This requirement is met when the veteran is substantially confined to his or her dwelling and the immediate premises or, if institutionalized, to the ward or clinical area, and it is reasonably certain that the disability or disabilities and resultant confinement will continue throughout his or her lifetime.
