In case you get unexpectedly sick during your stay in Lima and need medical care, there is no reason to panic. Health care in Lima's private clinics is very good and can withstand the comparison with hospitals in the US or Europe. Most private clinics are well-resourced with state-of-the-art equipment and internationally used standard medicines. In case of an emergency, you find qualified doctors and nurses treating you according to international standards and methods.
Please note that charges for doctors, hospitalization, treatments and surgeries vary heavily. But even those at the top end mostly only charge a fraction of the price you would have to pay for an equivalent private treatment in your home country. Anyhow, even if it is unusual for you, ask for exact fees and charges before you start your treatment to avoid any unpleasant surprises! It is also common practice here to pay any medical treatment or examination in advance! So, don't be surprised if you have to proceed to the cashier first to pay and then get examined or treated.
The clinics listed below are recommended by the foreign embassies in Lima and the international expat community.
