About the company
Arsenal Medical Insurance LLC (Arsenal MS), formerly the Crimean Medical Insurance Company, is one of the largest health insurance organisations in the Republic of Crimea and the city of Sevastopol. It has operated since 18 April 2014, and more than 1 million people have entrusted it with protecting their rights in the OMS system. Its charter capital is RUB 120 million.
The company works only in compulsory health insurance (OMS) under Bank of Russia licence OS No. 4324-01 (reissued on 27.05.2026). Its registered address is in Moscow; the main office for insured people is in Simferopol, Danilova Street, 43, letter G.
What a health insurance organisation and an OMS policy are
A health insurance organisation (SMO) operates in the compulsory health insurance system (OMS) under Federal Law No. 326-FZ. It issues policies, pays for the medical care of insured people out of OMS funds, checks the timeliness and quality of treatment and protects patients' rights, including through insurance representatives.
- The OMS policy is free — nobody should charge you for issuing it.
- The policy is valid throughout Russia: it entitles you to free medical care in any region.
- Today the policy exists primarily as an entry in the unified register of insured persons: the unique policy number, an extract or a digital policy on the Gosuslugi public services portal is enough; a paper form is issued on request.
How to choose or change your health insurance organisation
You can choose an SMO from the list of companies working in the OMS system in your region. The law allows you to change it once per calendar year — the application must be filed no later than 1 November — and more often if you move or if the SMO stops operating in the region. Apply at the office of the chosen company or via Gosuslugi; you will need a passport (a birth certificate for a child) and SNILS (individual insurance account number).
If a clinic refuses free care, misses the required time limits or asks you to pay for services covered by the state guarantee programme, contact Arsenal MS — via the contact centre or your insurance representative.
The company's website has dedicated information for military personnel, on care during pregnancy and childbirth, on dental treatment under OMS and on choosing a medical organisation outside your home region.
