What does the Units field represent on a UB-04 line item?

• A. The quantity of units of service or items provided for that line item.
• B. The number of days in the encounter.
• C. The patient's weight at service.
• D. The total charges for the line item.

Answer: (A)

The main idea is that the Units field shows how many items or how many times a service was provided for that line item. It tells you the quantity to multiply by the unit price to get the charge for that item or service. So if a medication is billed as 3 units, or a procedure is billed in 2 units, that number is recorded in this field and used to calculate the line item amount.

This field isn’t about the length of stay or days in the encounter, which would come from a different field, nor is it about the patient’s weight or the total charges. The total charges for the line item come from multiplying the units by the unit price and recording that result in the line item charge.
