Hi Heather,
Your primary care physician should either know the policy on coverage for these procedures in your state or be able to send a precertification request to Medicaid for you.
Sometimes there are several "levels" of review that have to be gone thru and I believe untimately you can appeal to your state's department of insurance if you feel you are being denied a medically necessary procedure.
There should also be a member assistance number on your medicaid card that you can also call for answers.
Congratulations on your weight loss success!
