How do I find a doctor in my medical plan?

Go to Find a Doctor on At Your Service. You will find lists of participating physicians on each insurance plan website. 

HMO medical plans require you to select a Primary Care Physician (PCP) to manage your care.  When you pick your PCP you are also choosing a medical group (e.g. Mercy Medical Center).  HMO physicians are affiliated with a medical group of specialists and hospitals that you may use for non-emergency care.  The PCP you select  will oversee your care and authorize visits to specialists in the medical group.
