A typical hospital has 20,000 or more charge codes, each with several attributes, such as price or quantity. During an EHR conversion, current charge codes are translated to new charge codes.
This translates to 20,000 potential points of failure on dozens of data attributes. Errors are inevitable, and even with 99% accuracy, hundreds, if not thousands, of mistakes occur due to the complex process. This is the primary source of revenue leakage during the EHR conversion process.
