The system provides universal coverage to all patients, including emergency care, preventive medicine, diagnostic procedures, surgeries (except cosmetic procedures) and medicine necessary to treat their condition. However, given budget constraints, these services are often unavailable in the majority of the country with the exception of major metropolitan regions, and even in those cities access to complex procedures may be delayed because of long lines. Despite this scenario, some patients were able to successfully sue the government for full SUS coverage for procedures performed in non-public facilities.
