Elderly grandparents immigrating to USA with no plan around health insurance, extremely concerned

Long story short, my elderly grandparents on my mothers side have recently been sponsored/approved for a Green Card through my aunt (mothers sister). I only learned of this recently, and both my father and I are concerned of the potential financial implications. My mother is only thinking through this from an emotional perspective, and wants to see her parents as they get older.

Grandmother is in her 70s, grandfather in his 80s. Both have a number of health issues (grandpa is worse off, and has dealt with heart issues in the past).

There has been no talk about how their health needs will be meet here in the US. The plan (at least initially) is to have my grandparents live with my parents for 4-6 months in California. God forbid they face any sort of medical issues while in the US, I imagine this could completely wipe my parents out.

Not being a health insurance expert by any means, I was hoping you kind folks could help me wrap my head around the potential financial implications here.

If I'm understanding correctly, it sounds like they may be eligible for Medi-cal…am I wrong?

Even with Medi-cal, their age and status of their health is causing alarms to go off for me. I am thinking of all the things that could go wrong during while they are here, which could potentially wipe out my parents financially.

I'm really just trying to get some rough ballpark figures so I can back up my argument that this is a terrible idea. Even if they are just examples (e.g. if your grandfather needed heart surgery while in CA and had Medi-cal, here is what sort of out of pocket cost your family could be looking at). Thanks all.
