I have done my research on the web for my particular pain issue. Usually the site will tell you but if your not sure, do the research and then call the doctor directly. That is how I have found my doctors but usually the big hospitals take Medicare. (CA) Unfortunately the big hospitals have their own politics and the waiting line is long for procedures etc. I had one hospital where I saw the doctor (had to wait a month for the appt.) then they scheduled me for the procedure a month later. By that time, I was in so much pain, morphine was the only thing they could give me to quiet down the pain and sometimes that didn't even help but they were quick to offer drugs but the appt. times were horrible. WATCH OUT for interns who are practicing. The big hospitals usually have interns. Research who the doctor is, the license and any information you can find out about the treating doctor.
My sports medicine doctor treats my pain issues and takes Medicare but I can tell, he really doesn't like it.
Medicare is a national healthcare plan. Medicaid is a state healthcare plan. So to find a doctor that takes Medicaid you would have to tell everybody what State you live in and then furthermore, the area of the state you live in. Otherwise it's a shot in the dark as to whether or not the doctor somebody tells you about is one that you would even be eligible to see (Medicaid is usually not active between two different states).
I hope you can find a doctor and get some relief for your pain.
I wish I could give you a direct answer. I have been on Medicare for many years and treated by many a doctor and it seem all they do is run up the bill. I am currently being treated by a sports medicine doctor (who accepts Medicare) and he had given me the shots i requested and said he understood my problems.
THEN after two shots, he came up with the excuse that Medicare does not pay for the shots that I was getting. I reported this to Medicare. I then called his office to find out that the doctor made a mistake and I could get these shots. NEXT, the doctor hurt his hand and cannot give me the shots and referred me to another doctor. The paper work was a nightmare but when i called my sport doctor for information, his office said, he is now giving shots again.
This is just one example of the Medicare nightmares I have gone through. When in doubt, report it to Medicare with name and info. There are SOME caring people at Medicare that actually do listen. I was just lucky this time but give it a try. Most doctors I have been to just spend the time treating basically, refill medications and then bill Medicare. Keep doing research on doctors and you might actually find a doctor that is serious about their work. Good LUCK!
