I didn't buy travel insurance at my initial payment but I can buy it within 24 hours of final payment, and I'm wondering if I need the preexisting medical coverage for food allergies? We have a family member with anaphylactic nut allergies. He hasn't seen a doctor or received treatment in the past 8 months for a reaction, but he's been under the yearly care of an allergist since he was a baby to have his epipens prescribed, etc. Are nut allergies a preexisting condition? That's the only reason (aside from a freak accident) that I could see us needing medical coverage, and I don't want to choose a policy that doesn't have a preexisting condition waiver and then have them deny a claim. But the coverage seems to be better/cheaper if I don't need the waiver. Any advice? Thank you!
