I am planning to invite my parents (74 and 65 yo) to Switzerland for a month, and I would like to have an insurance that would cover emergency situation with pre-existing conditions. They are both from India (mentioning country as there could country-specific informations).
Both have pre existing conditions - namely hypertension (takes medicine) for mom, and giant cell arthritis + steroid induced high blood sugar (undergoing long-term treatment with steroid) for dad. Both are in a fully stable condition, and they frequently travel inside their country. They never had any medical emergency in India.
I would like to have an insurance that would cover any EMERGENCY that might happen during the travel. ofc, I won't take them to outpatient treatment.
I am little confused on the terms and the laws - they are not accessible properly. If there is heart-attack will it be considered pre-existing condition? Heart-attack was never an existing condition -- however, can it be deduced from some other existing conditions?
To summarise, my questions are the following:
a) Is there any schengen travel insurance for Indians, that cover pre existing conditions (I know there are some popular options for US travel insurance, but I don't know sth for the Europe).
b) In general, what are the different emergency situations Y that are excluded because of the pre-existing conditions of x? Where I can get legal information about them?
Thank you!
