What should I ask a clinic abroad before booking?

I am comparing clinics abroad and getting a bit lost in what the quote really covers. One clinic list the procedure and hospital stay, another one also include transfers and follow-up, so the lower number dont tell me much.I found https://xcuro.com/ while making my notes, it helped me see which details to line up but Im still unsure about aftercare once your back home. For anyone who has arranged treatment overseas, what did you ask before booking? Accreditation, itemised costs and who handles complications seem important, maybe theres something obvious I'm missing. I'd talk it over with my own doctor too of course.
