The HMO Plan offers comprehensive coverage at a low out-of-pocket cost to you and your family. The primary objective of an HMO is to have only one physician coordinate a patient’s care through the HMO network of physicians, medical offices and hospitals. Under this plan, you MUST choose a Primary Care Physician (PCP) and a medical group that is in-network. If you do not, Anthem will assign a PCP and medical group to you.
