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 and the Group Insurance Fact Sheet

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.
