AMA is not a regulatory or licensing agency. Membership is strictly voluntary. Many of its purposes are political or policy-directive. Positions adopted by AMA are often persuasive to the medical field, including state licensing agencies, but only that.
My responses to questions on Avvo are never intended as legal advice and must not be relied upon as legal advice. I give legal advice only in the course of an attorney-client relationship. Exchange of information through Avvo's Questions forum does not establish an attorney-client relationship with me. That relationship is established only by individual consultation and execution of a written agreement for legal services.
The AMA does not issue licenses to practice medicine. It is not a government or regulatory agency. It is a voluntary membership organization. A doctor can apply for membership, and as long as he meets the AMA's standards for joining, he or she should be accepted. Being booted out from the AMA will have no impact on your license, by itself, and there could be many reasons that have nothing to do with your qualifications as a doctor that could cause you to lose your AMA membership.
