Cost of Coverage


Aetna DMO

Aetna is the carrier for the County’s Dental Maintenance Organization (DMO) plan. This is a pre-paid dental plan with private practice general dentists and specialists who participate with the plan.

If you enroll in the Aetna DMO plan you must select a Primary Care Dentist (PCD) to use your coverage. The PCD has primary responsibility for managing your dental care. Each DMO member must select a PCD. You can switch your selection as frequently as once per month. To designate your PCD, visit and click “login”, call Member Services at 1-877-238-6200, or complete a PCD Election Form. If you choose a new PCD on or before the 15th of the month, the change will go into effect on the first day of the following month. For example, if you change your PCD on April 15, the change will take effect May 1, and if you change your PCD on April 16, the change will take effect on June 1.
