If living here try to join a local insurance plan through one of the hospitals. There are many but if you have existing conditions or a checkered medical history or are overweight they likely will not cover you. In that case join one of the ambulance programs such as Cardio Movil. You pay a monthly fee for ambulance and doctor services and they come to your home. They also have a clinic with most specialists covered. You pay about $25US a month and then to see a doctor costs about $5. You pay more for minor procedures that that do but equal to what my co-pay was in the states mostly and of course you save on the annual insurance and deductibles.

Get a good expat Major Medical policy that will cover you for serious issues but if you don't use doctors a lot this works out to be a huge savings. Note that most international Hospitalization plans will cover you anywhere in the world but in the USA. They will of course if you are willing to pay for it but you could go to Argentina or France or England instead if you don't want to be hospitalized in Uruguay.

There are Hospitals and clinics quite close, say about 10-20 minutes from anywhere and there is a plan for a huge medical complex to draw in medical tourism.

Hospitals are Cantegril and Mautone that I know of and use and they are private. Most are private and I don't recommend the public ones.
