A Co-Share is the percentage of an Eligible Medical Bill paid by the member after the Primary Responsibility Amount (PRA) has been met.
Watch this video, "What is a Co-Share?"
As an Impact member, after your PRA has been met, you pay 10% of all Eligible Medical Bills. The remaining 90% is Published for Sharing to the Impact membership.
There is a Co-Share limit of $5,000 annually per household. In other words, after a member pays a total of $5,000 in Co-Shares, they will not be subject to a Co-Share until the amount resets on their Membership Date.
