Can social security only pay medical insurance?

Self-participation in social security is limited to urban and rural residents' social security and flexible employment social security, both of which only include endowment insurance and medical insurance. Medical insurance should be paid together with endowment insurance, but endowment insurance can be paid separately. Legal basis: Article 23 of the Social Insurance Law stipulates that employees should participate in the basic medical insurance for employees, and employers and employees should pay the basic medical insurance premiums in accordance with state regulations. Individual industrial and commercial households without employees, part-time employees who have not participated in the basic medical insurance for employees and other flexible employees can participate in the basic medical insurance for employees, and individuals pay the basic medical insurance premium in accordance with state regulations.
