Wellmark Blue Cross and Blue Shield will partner with two other Greater Des Moines companies to offer a new health insurance plan providing discounts to policyholders, provided they access services through those companies, Wellmark announced on Friday. The Des Moines-based insurer will work with UnityPoint Health and Hy-Vee Inc. to provide the new plan, called Blue Rewards. Under the plan, policyholders would receive discounts for using UnityPoint Health's network of hospitals and clinics and filling their prescriptions at Hy-Vee pharmacies. The collaboration will also make available health-related options from Hy-Vee such as health assessments, wellness screenings, nutrition counseling and healthy food options. Wellmark officials said the concept is the first of its kind in Iowa, but "is consistent with national trends that extend the convenience of health and wellness into environments where customers live, work and shop." Subject to approval by the Iowa Insurance Division, the plan is expected to be available for the 2015 open enrollment periods this fall.
