In Jerusalem, as well as the rest of Israel, there are four major health care services.
The medical system in Israel is socialized, meaning it is government-run. As a result, citizens pre-pay for medical care and when a doctor is needed the visit is (for the most part) free.
The following is a list of public medical institutions.
Clalit Health Services
Leumit Advanced Personal Healthcare
Meuhedet Health Services - Hebrew Only
Maccabi Healthcare Services
