According to the Bureau of Labor Statistics, medical assistants employed by psychiatric and substance abuse hospitals have the highest hourly wages, with an average salary of $39,220.
The medical assisting salary has consistently risen over the past decade. In 2004 medical assistants earned an average income of $23,332 according to the American Association of Medical Assistants (AAMA) which regularly conducts income surveys. Compare this to the 2011 nationwide average annual salary of $30,170 supplied by the US Bureau of Labor. Because this is the average salary for the medical assistant sector, some assistants earn more and others earn less than this average. In fact, the pay range among medical assistants is significant. Some earn as little as $20,810 annually, while other experienced medical assistants enjoy an income as high as $40,190.
