If someone has a lot in savings and owns their home, but gets diagnosed with a horrible disease, can they get medicaid to avoid bankruptcy?

Thinking about medical bankruptcies given the news of the actor who died today. Their family set up a GoFundMe due to medical bills even though they appear to be wealthy and allegedly have multiple homes. Would someone in that situation, who presumably had savings and allegedly multiple homes at the time of diagnosis, and who was not employed as an actor at the time of diagnosis, have been able to get on Medicaid when he was first diagnosed in order to not end up in the current financial situation?
