What do Occurrence Span Codes specify on UB-04?

• A. The duration of events affecting payment.
• B. The admission date.
• C. The patient’s age.
• D. The payer’s contact info.

Answer: (A)

Occurrence Span Codes specify the duration or date span of events that affect payment on the UB-04. They work with an Occurrence Code to tell the payer how long the event lasted or over what period it occurred, which can influence how the claim is reviewed and paid. The actual date of the event is captured elsewhere, but the span code communicates the length or time window of that event. This helps explain billing implications when an event isn’t confined to a single day, such as an injury or condition that spans multiple days. Other items like admission date, patient age, or payer contact information relate to different sections of the form and don’t convey the duration of events that affect payment.
