Jeff, insurance is a very frequent topic. This is the past year’s posts on the subject https://search.ricksteves.com/?button=&date_range=1y&filter=Travel+Forum&query=Insurance&utf8=%E2%9C%93
As you are seeing, there is comprehensive travel insurance, separate medical insurance and separate evacuation insurance.
Your biggest loss will be if you become sick or injured and need/want to be medical evac’d home. Unless you have a spare $100,000 or high risk tolerance, you want to cover that. Look at https://medjetassist.com/
If you paid any money for your trip more than two weeks ago, pre-existing condition coverage may not apply. Look at GeoBlue if that is the case https://www.geobluetravelinsurance.com/mobile/index-2.cfm
Fortunately, I have not had to file a claim. In the past I bought Allianz for comprehensive, GeoBlue for medical, Medjet for evac.
