I have lived here in Querétaro state for a few years, and in Latin America for the past 15 years. I have used the local hospital for treatment and surgery with 4 doctors attending. (Orthopedic surgeon, a GP who did the drilling

, the anesthesiologist and the radiologist). The cost for everything - doctors, surgery, 5 days in the clínica and including 4 months of follow-ups was about US$3600.
The primary doctor was an orthopedic surgeon who spends two weeks each year in Cuba for additional training, and he has about 25 years experience. And an unhurried, pleasant bedside manner. I would put him up against any other orthopedic surgeon/doctor in North America.
This clínica would compare to a 3 star hotel, with only 6 private patient rooms and a couple of wards, and hospital costs run less than US$90 a day for a large private room. It was spotless, quiet and plenty of nurses.
I also had a tumor removed (internally) from my arm in outpatient-type surgery by a specialist at Clinica Angeles in Querétaro. The total cost for this was about US$300.
Normal doctor appointments run about MX$400, or MX$600-$700 for a specialist in Querétaro. Biggest difference - I rarely have to wait more than 5 minutes to go in to see the doctor.
I may live in a sheltered place, because I NEVER encounter ****** prices locally. Then again, there are very few gringos in my area and I am fluent in Spanish.
I priced an international medical policy, and my cost would have been more than US$9000 a year. It will be many years before I am eligible for Medicare. I do maintain a major medical policy in the US with a high deductible in case of something huge, like cancer or a heart transplant, but nothing more. Out of pocket for the routine medical things here seems to be much cheaper than insurance for me. Not to mention, no endless telephone calls, documentation, translations, and the normal insurance company runarounds.
