Medical Billing Collections

I am in need of assistance with medical billing collection services focusing on patient collections for a medium-scale operation of 100-500 clients. I already have specific billing software - Intellect, Prime Clinical Systems, that I am using, and I'm hoping to find an experienced freelancer with the skills and knowledge to help me manage my collections. The successful bidder should have a demonstrated understanding of medical coding, medical bills, payment posting accuracy, and excellent reconciliation and processing skills. A strong background in customer service is also important, as many inquiries will need to be handled in a timely and sympathetic manner.
