Medical Record Number. A unique patient identifier, as required by HIPAA, which is provided by a healthcare provider or healthcare system. Patients do not have a universal MRN as they are provided separately by different healthcare systems. An MRN will not change throughout all of the care received within a health system - unlike an account (called a HAR in Epic) or visit number (called a CSN in Epic). Hospitals typically use MRN, in conjunction with SSN, as unique patient identifiers.
