*The CalOptima Health OneCare Flex Plus grocery benefit is part of a special supplemental program for the chronically ill. Not all members qualify. To use the grocery benefit, CalOptima Health OneCare Flex Plus members must have one or more comorbid and medically complex chronic conditions that are life threatening or significantly limits the overall health or function of the enrollee. Eligible conditions include but are not limited to cardiovascular disorder, diabetes mellitus, chronic heart failure, chronic lung disease or end-stage renal disease. Even if the member has a chronic condition, the member will not necessarily receive the grocery benefit. Receiving the grocery benefit depends on the member having a high risk of hospitalization or other adverse health outcomes and a need for intensive care coordination.
