Which field records the date range of service when a line item spans multiple days?

• A. Dates of Service
• B. Admission Date
• C. Discharge Date
• D. Service Start Date

Answer: (A)

Dates of Service is the field that records the date range when a line item covers more than one day. When a service spans multiple days, you need to show the entire window (for example, from a start date to an end date) so the payer understands exactly how long the service occurred and can bill appropriately. Admission Date and Discharge Date relate to the patient’s overall hospital stay, not the duration of a specific line item. A Service Start Date only marks the first day and doesn’t convey the full span unless you also include the end date. So the date range for the service is captured by the Dates of Service field.
