Right now, for the most part, Medicare acts like health insurance, but does not cover Long term Care or nursing home care. Primarily, Medicaid is used for long term care, and you have to qualify (which isn't easy). However, Bernie Sanders is proposing a new expanded Medicare program that would cover long term care in a nursing home. The article by the Associated Press states that "The House bill — known as H.R. 1384 — emphasizes home- and community-based care in the “least restrictive setting.” But it would also pay for nursing home care. The earlier version of the House bill included a few mentions of long-term care but did not specify benefits."
Honestly, I think it's unlikely to pass. All the news in the Medicaid world is about cutbacks, NOT expansion. Still, if this came to fruition, it would be amazing.
