State of California Benefits Identification Card?
is this a medical/ medicare insurance card?
if so, how can i find a pediatrician online that is a participating physician?
Answers: Your county and/or your state have a list of doctors who contribute.
Contact the county first, as this is probably a local call.
Once nearby, ask for the website address.
With luck, however, you can do an search for the term of your county and the name of your state. Once you hold the site, do a search inwardly the site for such a listing.
If this fail, contact the county health department or the medical association for your community.
