Medical Billing and Coding can be done from anywhere, which is why so many companies now outsource the job to independent contractors or employees who work from remote locations. This makes the job very attractive to people who want to be able to work from home.
Best of all, the job is fairly easy to learn and the training for it that once required attending classes is now available online for a fraction of the cost of traditional trade school tuition.
You should also take advantage of some of the available resources to help you take and pass the required CPC (Certified Professional Coder) exam that many employers look for when hiring Medical Biller/Coders. One such program can be found here.
