Another alternative is OSDE - the country's largest 'obra social' or healthcare provider. I've been covered by them for 15 years and I never cease to be amazed at the quality of service I get. With my standard '210' plan I get free doctor, dentist, physiotherapist, clinical studies, X-rays, colonoscopy, and anything else my doctor may order for me as a precaution - I've never had to pay a cent en extras or deductibles. One monthly payment (of $16,288 - for me 55 years old and my 16 year old son) covers it all, plus discount on any medicines they prescribe. They have so many affiliated professionals that, if you live in CABA, you never have to go more than a few blocks to get treated.
