 ### Conventions 
 The COST table will store information reporting money or currency amounts. There are three types of cost data, defined in the cost_type_concept_id: 1) paid or reimbursed amounts, 2) charges or list prices (such as Average Wholesale Prices), and 3) costs or expenses incurred by the provider. The defined fields are variables found in almost all U.S.-based claims data sources, which is the most common data source for researchers. Non-U.S.-based data holders are encouraged to engage with OHDSI to adjust these tables to their needs.
