I cannot find a proper travel insurance that covers work related travel. All major companies seem to exclude "Geschäftsreisen" (company travels). I know our university does not provide this cover, nor do colleagues know an alternative. (They seem to travel without appropriate cover ).

Since I am going to the US, I really would prefer cover that does not exclude work related travel! Any tips from anyone would be really appreciated. (I have googled much but no luck yet).
