Which of the following is NOT one of the four main functions of EHRs/EMRs?

• A. Computerized prescription ordering
• B. Billing and revenue cycle management
• C. Capture of physician notes
• D. Order entry for tests

Answer: (B)

EHRs/EMRs are built to support clinical care by handling patient information and the flow of care: documentation of encounters, electronic ordering for tests, electronic prescribing, and access to test results. Billing and revenue cycle management, while often present in integrated systems, is a financial function focused on coding, claims submission, and payments, not a core clinical workflow. That’s why it isn’t counted among the main clinical functions. The other options fit the clinical side: capturing physician notes for documentation, computerized prescription ordering for medications, and order entry for tests are all fundamental to how EHRs/EMRs support patient care. The fourth core function typically associated with these systems is results management, which aligns with delivering and reviewing lab and imaging results.
