Computer-assisted coding software and electronic medical records are just two advances that have changed the jobs of medical billers and coders. These technologies can automate some tasks that billers and coders traditionally execute. That said, "There's still a need for medical billers and coders, regardless of strides in computer-assisted coding and electronic medical records," Garcia says. She points out that a human still needs to double-check any automated billing and coding to ensure accuracy. Plus, "a computer is only as smart as you're telling it to be. We still need billers and coders to reason out what is in the documentation." The bottom line: Technology and automation are changing the field, but healthcare organizations continue to hire medical billers and coders.
