The increase in the negative amount means that the medical expenses are paid by the basic medical insurance fund, but a certain proportion of the burden needs to be increased. In layman's terms, it is the conceited part. For example, a 5% increase means 95% medical insurance and 5% out of pocket.

The basic medical insurance co-ordination fund, also known as the basic medical insurance fund, refers to the special fund for basic medical insurance for employees raised by medical insurance agencies from insured units and employees in accordance with the relevant provisions of the state.
