If you have the means for it, then try not to depend on the state health insurance, which is part of the Portuguese social security system. Depending on it means only access to state hospital that usually have a very long waiting list for treatments (sometimes people literally have to wait years). Private insurance generally means very short or no waiting for treatments, plus access to private clinics (offering higher quality in health care).
