We perform Charge Description Master reviews using a new PHP/Linux driven application that can be customized to practically any niche (but is currently being used for Charge Master reviews). The data we analyze is then used to provide corrections to Hospital Billing, which leads to millions of dollars in recovered revenue.We're also a guardian for hospitals in a sense, as we find very big mistakes that could, for example, lead them to audits by government agencies. We fix these big mistakes so that they are billing legally and accurately, while at the same time finding lost revenue to recover.
