The answer depends on how much you know about medical coding and if you can find a system that meet your needs. Many colleges offer medical coder certification program. Just taking one or two courses will help you a lot. Alternatively, you can hire a part-time medical coder to help out and learn from the experience. As for billing system, use one that is integrated with your EHR. This will help you avoid a lot of pain.My clinic is currently using Solismed EHR, and its integrated billing function is relatively easy to use. The nice thing is that it's only $50 a month for the entire clinic.
