Which statement best describes the difference between an electronic health record (EHR) and an electronic medical record (EMR)?

• A. EHR is comprehensive health history across settings; EMR is specific to a single visit.
• B. EMR is comprehensive health history across settings; EHR is specific to a single visit.
• C. They are the same.
• D. EHR is only for billing.

Answer: (D)

Interoperability and scope drive the difference. An electronic health record is built to be a longitudinal, comprehensive record that can be shared and used across different health care settings and providers. It brings together data from multiple encounters, labs, imaging, medications, and care plans to support coordinated care, reduce duplication, and enable information exchange among clinicians and organizations. An electronic medical record, by contrast, is the digital version of a patient’s chart kept within a single practice. Its data are typically limited to that practice and are not designed for broad interoperability with other providers or systems.

The idea that the record is only for billing isn’t accurate. While billing information may be included, the primary purpose of an EHR is to support clinical care across settings, not just administrative tasks.
