A year, once, a month. The duration of medication is not more than one year, and the dosage at a time is not more than one month.

It is worth noting that the filing of special drugs is not once and for all. In these cases, insured patients need to re-apply for filing:

1. Need to continue to use after the drug declaration period;

2. Need to adjust the category during the medication cycle;

3. Those who have not been treated for more than 6 months after being confirmed by the responsible physician for special drugs and have stopped treatment for more than 3 months.

In addition, if the insured patients use the special drug expenses provided free of charge by drug manufacturers or charities such as foundations and charitable associations during the treatment, the medical insurance fund will no longer pay.
