I think I understand what happens on a single-trip policy if, after buying the cover, and before travelling, some new medical information comes to light (a new diagnosis, or one suffers new symptoms) — the policyholder is due to tell the insurer, who then gets to decide whether to cancel the trip and pay compensation, or let the trip go ahead. This makes sense for a single-trip insurance.
What about an annual policy? If the insurer in informed of a new medical condition during the period of the policy, what can the insurer do? Presumably the insurer has the choice to cancel any booked travel, in exchange for paying compensation, but what happens to the rest of the annual policy? Are all future trips uninsured? Is there compensation for curtailing the insurance?
Thanks for any clues,
