Is it possible to address the clinics, not listed in the Voluntary Health Insurance program?

In cases when there is a need of a consultation of a domain expert or diagnostic study, which cannot be provided by the local treatment facilities under the policy, the Insurance company organizes and pays for all the required services in the clinics with the aforementioned capabilities. An appeal to a medical institution not stipulated by the insurance program is only possible following the approval by the Insurance company. In such cases there can be several payment options – a payment by the Insurance company or the Insured person pays with later full or partial reimbursement of the services cost.
