{description: '\"A FDA Establishment Identifier or Firm Establishment Identifier (FEI) is an FDA system generated number used to identify a firm. FDA systems interact, occasionally creating multiple records (FEIs) for one firm. Upon evaluation, these numbers are merged into one surviving FEI which is used to identify the firm. The remaining FEIs become children of the surviving FEI and are not used to identify the firm.\"\r\n\r\nFor more information, see [https://www.accessdata.fda.gov/scripts/feiportal/index.cfm?action=common.faq](https://www.accessdata.fda.gov/scripts/feiportal/index.cfm?action=common.faq).', package_name: hl7.terminology, name: FEI, type: null, package_version: 7.0.1, class: identifier, kind: identifier, url: 'http://terminology.hl7.org/NamingSystem/FEI', version: 1.0.0}
