Mapping and semantic enrichment of financial data. An example of code-matching between the financial system and the current inpatient pharmacy module, with links to RxNorm. Warfarin, 5 mg oral tablet in the financial system had a charge code of 7056345, which matched to a single item in the current inpatient pharmacy module. This item had the main Multum drug code (MMDC) 3616, which mapped to RxNorm code 855332, which could now be assigned to the charge code. Matching and enrichment of financial codes using RxNorm allowed for queries in the financial data using RxNorm.
