If you have a preference on doctor, than absolutely yes. If no, then probably not.
My primary did not accept Medicaid patients. She also didn't accept all of the ACA plans. I looked into moving to another doctor, and she also didn't take all the ACA plans, and didn't take Medicaid. This is from my notes:
Dr. A Preferred HMO, select HMO, premiere PPO, not Metro Detroit
Dr. P Preferred HMO, premiere PPO, Metro Detroit
It's ridiculously complicated. Also, be sure to call your doctor's office directly and confirm, because sometimes the websites don't reflect the most current information.
I wouldn't hesitate to take Medicaid on moral grounds. Your tax dollars pay for these benefits. Congress has had almost 10 years to close this loophole.
