Should the worst scenario play out while you’re on your trip around Russia, know that there are many medical facilities waiting to take care of you. In particular, the Hospital #122 in Saint Petersburg should be of note to foreign travelers. The reason why is that this hospital in particular offers a vast collection of high-tech equipment needed for modern Western medical techniques that many of the smaller hospitals in the rest of the country still lack.
Travelers who fall sick in Russia and receive care elsewhere first usually end up being ultimately sent to Hospital #122, simply because the facility is so well equipped to perform complex jobs like mysterious diagnostics that have baffled other facilities. Emergency surgery is also available at this hospital should the worst of the worst happen. Hospital #122 is fully equipped to accept a variety of insurance, so if your provider is reasonably well known, you should be covered.
