We are headed down 11/19 and all I did was email our insurance company (BCBS AL) telling them I needed a coverage letter that stated our policy would cover us outside of the United States and that it did include Covid coverage. They responded with an email asking who all on the policy was going and what the dates were. They are sending us their standard international travel letter. Not sure about other BCBS plans, but our does specifically say that we are covered for medical repatriation as long as we are not outside of the US for more than 90 consecutive days.
