Yes, a draconian system that makes it easier for third parties (insurers) to deny payment. By changing several hundred codes per year, the AMA raises physician overhead while making it more difficult for them to be reimbursed for services rendered. Doesn't sound like an entity focused on the best interests of doctors, at least not anymore.
AMA supported the Affordable Care Act which most physicians opposed. If they truly represented Doctors, then they would have opposed it as well. There may have been a time when the AMA supported the best interests of Doctors but that time has passed. AMA is more in cahoots with the Pharmaceutical industry, insurance industry and hospital industry than they are with Individual physicians.
