Brief Overview of Health Insurance at CBS
Students pay approximately $300 per semester for basic medical services, not including a prescription plan (see your to-do list). This basic coverage includes access to the center’s RNs and MDs, Emergency Room coverage up to $2,000, termination of pregnancy coverage up to $500, off-campus psychological service, and out-patient substance abuse treatment.
For additional or prescription coverage, students may elect to purchase a Student Medical Insurance Plan and many people opt for the school`s more comprehensive plan (more covered, less copay).
More on Student Health Care and Insurance (mostly useful for international students)
Health care in the United States is very good but very costly. There is no national medical care system or insurance program. You must pay for medical services. Hospital costs in the New York area can be $2,000 a day, and that does not include physicians’ fees, which are also very high. One cannot afford to be without medical insurance.
For this reason, the University requires all full-time students and strongly urges all dependents either to subscribe to the University’s Student Health Insurance or to have proof of comparable medical coverage. If you believe that you already have, or can purchase a policy at home, be very sure that it is comparable to the one offered by Columbia. If not, you will not have your insurance requirement waived, and will end up paying for two. This has happened to international students in the past, so be careful. The Health Services web site has information on comparing medical coverage at http://www.health.columbia.edu/.
If you and any dependents are in J immigration status, immigration regulations relating to your status require you and your family to have a comprehensive health insurance policy in order to maintain your status.
The university offers a two-part health care program: the Health Service and the Student Medical Insurance. All full-time students are also required to pay the Student Health Service fee each semester. The Columbia University Health Service provides a comprehensive range of programs to help students stay healthy and productive during their time at Columbia. Primary care, counseling, health education, and other medical services are offered free or at a nominal charge to students who have paid the Health Service fee. The clinic is staffed by full-time professionals and part-time specialists. Morningside students use the University Health Service located on the third and fourth floors of John Jay Hall (212-854-2284), while those registered at the Medical Center use the Student Health Service located on the street level of 60 Haven Avenue (212-305-3400).
