The co-payment is the amount you pay towards the cost of your PBS medicine. Many PBS medicines cost a lot more than you actually pay as a co-payment.
From 1 January 2015, you pay up to $37.70 for most PBS medicines or $6.10 if you have a concession card. The Australian Government pays the remaining cost.
The amount of co-payment is adjusted on 1 January each year in line with the Consumer Price Index (CPI).
