Titre Why have I reached my maximum contribution? Answer Réponse Each time you purchase covered drugs, you pay a portion of the monthly contribution. If you reach the maximum contribution amount before the end of the month, you can usually obtain other covered drugs free of charge until the end of the month. The maximum contribution amounts may vary depending on your situation. They are adjusted on July 1 each year. If the cost of your drugs changes, the point at which you reach your maximum contribution may also change. Learn more Understand your pharmacy invoice
