Generally, you may change your coverage only during the annual Open Enrollment period held in October, unless you are in an HMO and moving out of the HMO coverage area.

If you are moving and need to change your health care coverage, contact the Employes' Retirement System at 414-286-3557 (or toll free at 1-800-815-8418).

Changes made during the Fall Open Enrollment period become effective in the next calendar year. To help with your enrollment, benefits sessions are offered at various locations during Open Enrollment.
