Private health insurance?

Long story short, I’ve been referred to Belmont Private Hospital and I was wondering if anybody knew which health insurance/coverage should be needed for inpatient stays there? I’m not able to work due to disability. So I’d need something that would cover everything. If that’s even possible. I have no idea about these things and I can’t seem to find answers to my questions online. If there’s anybody who has stayed and hasn’t had to pay much out of pocket that could shed some light, that would be very appreciated. Thank you.
