Hi CSNOOKY1A,
It's good to get your message. In Uruguay, you have a number of private health providers. Each sets their own acceptance standards. The British Hospital is the most strict, in that it does not take new members over 60. (I started with the British Hospital when I was still in my 40s.) One of the most popular private health care providers among expats over 60 is Asociaón Española. I know people who were accepted as new members into their late 60s.
Here is a link to an article I wrote going deeper into the range of healthcare options available in Uruguay. https://internationalliving.com/countries/uruguay/health-care/
Let me know as additional questions about Uruguay come up.
