I've recently researched this for someone. Can't talk about each and every carrier, but Allianz definitely say on their website that it isn't covered. iTravelInsured (IMG) also said not covered. Other policies I've looked at specifically exclude anything pregnancy related past week 26.
If the insurance only excludes "normal childbirth," does that include premature (before 37 weeks)? Is there a way to know for sure, or is it a gray area that can be interpreted either way?
I bought a policy with iTravelInsured and it only excludes "normal childbirth"," but it doesn't define that.
