How old is the medical insurance card?

Legal analysis: you need to be 16 years old to apply for a social security card, and you can't participate in social security beyond the statutory retirement age. The old-age insurance included in the social security of urban and rural residents must be 16 years old or older, and the medical insurance can be insured from birth (in some places, prospective newborns are allowed to participate), regardless of age.

Legal basis: Article 23 of the Social Insurance Law of People's Republic of China (PRC), employees shall participate in the basic medical insurance for employees, and both employers and employees shall pay the basic medical insurance premium according to the provisions of the state.

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.
