Congratulations on an excellent article, possibly unique.
One additional point I would raise is please check what hospitals and what doctors are covered. Not easy… I have seen some policies are restrictive - some allow you to go to anyone, some say only in a preapproved emergency and others say you are responsible for any price difference.
I have had patients only eligible in India for unacceptable hospitals in that city or the option to travel hundreds of miles which isnt appropriate
In the US I have had policies that only cover network A of doctors in a hospital but network B is on call
In London we have had only hospital A covered but it doesnt provide that service, and the amount the insurer claims is paid to the approved doctor is so low no doctor will accept that fee and the patient has a massive shortfall.
Finally, as others on this site have pointed out, make sure you can start treatment without delay or too much hassle.
