Finding a provider who accepts Medicaid patients has the potential be a little confusing to the individuals who have never been on the program before, but it's not as difficult as it may sound. All you need is to be enrolled in Medicaid or CHIP coverage and have a connection to the internet.
Some states have far more resources to help those individuals to get connected with a provider and other states do not, but the best resource to begin your search is by using the Centers for Medicare and Medicaid Services "Physician Compare" tool.
Once you go to the "Physician Compare" website then you will need to type in your city or zip code and then type in "Medicaid Providers." You will then be taken to a page that lists all of the doctors and hospitals that accept Medicaid in your area.
Another thing you can do is call the member services phone number on your eligibility letter or the back of your enrollment card. They will be able to provide you with a list of medical professionals who accept Medicaid recipients.
If you aren't currently enrolled in Medicaid and wonder if you are eligible for the program than you will need to are eligible apply for coverage before searching for a physician. Applying for coverage is free of charge, but it is not guaranteed that you will be accepted. That will depend largely on how much you or your family makes each year and what state you live in. If you live in a state that expanded their Medicaid program then your income threshold will be higher than individuals or families who live in states that chose not to expand the program.
If you have any further questions then I would refer you to the "Using your new Medicaid or CHIP coverage" page on Healthcare.gov. The page answers frequently asked questions and provides you with a list of resources to help you utilize your coverage.
