There were some discussions in the past on this topic but they were from years ago. Pls suggest if anyone has used any for their visiting parents and actually got the claims paid off. Typically I hear are: 1. INF 2. Patriot America 3. Insu Buy
None of them cover pre-existing conditions. Diabetes, heart attacks etc may not covered. They may cover unforeseen accidents like fractures, sprains etc.
We had good experience with INF. Mom-in-law had dislocated shoulder, later diagnosed with fracture as well. INF paid as promised. Their health insurance card was accepted at all the places. They are pricey but they paid what they promised. This incident happened in 2023.
