Cost share refers to the percent retirees pay for County group insurance; the County pays the remainder. Each year, the Office of Human Resources Health Insurance Team mails retirees two communications that include cost share information: the Group Insurance Fact Sheet (sent with Open Enrollment packets in mid-October) and the Open Enrollment Confirmation Statements (sent in December each year).

Retirees who elected the 20% cost share upon retirement, pay 20% of the premium and the County pays 80%. When this cost share expires, they begin to pay 100% of the premium and the County pays 0%. The cost share expiration date cannot be changed. It can be found on the Open Enrollment Confirmation Statement sent in December each year.
