HMK Basic Dental Plan:

HMK Extended Dental Plan:

HMK offers an Extended Dental Plan (EDP) providing coverage for dental services beyond the HMK Basic Dental Plan. Dental providers must submit a "Request for Extended Dental Benefits" form including a proposed treatment plan. The treatment plan must be approved by HMK before a child is determined eligible for EDP benefits. The dental services must be provided within 90 days of the approval determination.

The Extended Dental Plan is an ongoing benefit of HMK. However, EDP funding is limited. When all funds are allocated, new funding is available again the following July 1. If a child previously received EDP services, please contact HMK to find out if he/she is again eligible.
