Most importantly, get a private expatriate health insurance policy from a worldwide insurer that covers you in EY. For me where I am, AXA/PPP is the best but everyone needs different coverage so check out other offers as well. AXA/PPP covers you in EY so long as you will be there more than 6 months out of the year; it covers you everywhere else you travel as well except the US.
The price is not high, even for a zero deductible policy, compared to US private insurance, and you can then use the best doctors and facilities in EY on a priority basis rather than waiting for routine procedures with Kupat Cholim.
You can also get care in Europe should the need arise (taking US coverage on an expat policy is wildly expensive).
