The Anthem website's home page contains a "Find a doctor" link in the right-hand "Useful tools" side bar that can be used to determine if a particular doctor, dentist, pharmacy or hospital is in the Anthem Blue Cross Blue Shield network. The page that the link brings up enables visitors to perform a search by either choosing a state and a plan, or by entering their plan ID number if they are already a member, as shown on the Anthem "Find a doctor" page.
Non-member visitors can determine if a doctor is in a particular network by entering the doctor's name after choosing the state, plan name, doctor specialty, a location and the distance in increments of up to 100 miles. If a specific doctor's name is not entered, the search results will display all of the network doctors that participate in the plan. The search can also be refined by choosing one or both of the optional criteria "accepting new patients" and "able to serve as primary care physician." An "Encontrar un doctor" link enables the search to be performed in Spanish. Updates are typically made to the search tool on a weekly basis, as noted by the Anthem website.
Anthem Blue Cross Blue Shield was formerly called WellPoint up until its official name change in December 2014 and, as of 2014, it has more than 37 million members, as reported by Forbes.
