All registered students are required to have health insurance. Call (650) 723-2135 for more information. Cardinal Care, the University-sponsored plan for students, fulfills this requirement. Insured by Aetna Student Health (medical), and ValueOptions (mental health), Cardinal Care features comprehensive, worldwide coverage, services by referral at Stanford University Medical Center and Menlo Medical Clinic, and lowest costs when one initiates care at Vaden Health Center. Stanford does not sponsor a health insurance plan for dependents; for available options, see http://vaden.stanford.edu/insurance/dependent.html. Options for voluntary dental insurance are also offered.
