General insurance companies can provide green services for serious diseases, including expert outpatient service, expert consultation, surgical treatment and transportation subsidies. Different insurance companies may provide different services. You can't enjoy the green service for serious illness as long as you buy insurance. Please consult the insurance company about how to obtain it. For example, some insurance companies sell their products and provide green link services, which can be enjoyed after purchasing insurance, and some insurance companies need to pay premiums to provide this service, and so on.
