Expat health covers new medical conditions, accidents or emergencies that first commence after your policy has commenced.
It does not cover pre-existing conditions that were known, treated or diagnosed before the policy commenced.
Therefore, if you first develop a chronic condition after your policy starts, then it would likely be covered.
But if you already have a chronic condition before your policy commences, then it would be considered a pre-existing condition and would not be covered.
In any case, you are still eligible to sign up for Expat Health with us and pay for treatment related to pre-existing conditions out of pocket.
