Constitution d’un référentiel probabiliste d’aide au codage

Because giving a code to something is a non-intuitive operation, it leads us towards committing mistakes, which may have some bad consequences. In medicine, physicians and such have to assign a code for everything they do and they are not spared with these kinds of errors. This report is about a way to help the medical coding task in order to minimize error without losing time by giving some codes that may occur in consequences of what the practionner is doing and of his patient characteristics. It describes different medical information sources in order 10 have these predicted codes and tries to determine which one is better. In order to achieve this objective, a method based on the probability to have a diagnostic given a specific medical information (which is already presents in the pmsi) has been developed.
