There are two primary types of health insurance in Russia: the compulsory insurance known as OMC, and privately purchased medical insurance, or DMC. OMC is provided by the state and is provided free to Russians, but many vital treatments and procedures are not covered by the compulsory plan. In addition, OMC applies only to treatments at a specific hospital; if a person covered only by OMC become ill while travelling, even within Russia, he or she will not be covered by OMC, and will have to pay in full for medical services, except in emergency cases that require calling an ambulance.
For this reason, people from abroad, including international students, are encouraged to purchase private health insurance in Russia. International students should consider purchasing medical insurance in Russia that covers both medical care in Russia, and medical evacuation back to their home country. It is generally wise to check to make sure your insurance policy covers medical evacuations before your stay in Russia, as medical evacuations are very expensive. In some cases, however, they are the only option, as the quality of Russian medical care varies throughout the country. Most patients from abroad pay for medical services in cash and receive reimbursement from their insurance company upon their arrival back home.
