If it is not a new booking, you won't be able to get CFAR. Even using EI "money" might prevent that, depending on the company. The older you are, the more expensive the insurance.
You can go to tripinsurancestore.com and use their "side by side comparison" link to see the cost, coverages, and options for your trip from a number of different companies. If the trip cost is >= $25,000 per person, there will be a lot less choices shown.
