Has anyone used pacific cross for the insurance provider , looking at the Maxima plan . Applying for an OA visa I'm from the USA. Any thoughts ? I do have a pre-existing condition but take no medication , use diet and exercise to help to alleviate symptoms.

I don't know if I should let the insurance company know about pre-existing condition when filling out paperwork for any kind of Thai health insurance when applying? Thanks for any feedback from their experience with this or anything might be related to this topic.
