Coverage for illness during overseas travel

Good Evening,

I don't want to get into too much details on this forum, but long story short, I was on a business trip to Brussels in Belgium and I contracted a disease for which I was treated at urgent care. However, my doctor here isn't able to access this information and isn't sure that following procedures would be covered. Is there anyone who can give me this piece of information?

Thanks
