Which data elements on UB-04 capture patient demographic information?

• A. Address and contact information only.
• B. Medical history and allergies.
• C. Patient name, date of birth, sex, address, and related identifiers in the header sections.
• D. Discharge disposition and transfer details.

Answer: (C)

The main idea is that UB-04 stores identifying patient information in the header as demographics. The header sections hold the essential identifiers used to recognize and track the patient across encounters—things like patient name, date of birth, sex, address, and related identifiers (such as patient control or account numbers). This demographic data is what uniquely identifies who the claim is for and links the record to the patient’s chart.

Why this option fits best: it explicitly lists the elements that define patient identity and are located in the header, covering name, birth date, sex, address, and the related identifiers. Other options focus on information that isn’t demographic: medical history and allergies are clinical data, not demographics; discharge disposition and transfer details pertain to the hospitalization’s outcome, not who the patient is. Address and contact information alone also misses key identifiers and basic demographic fields like name, date of birth, and sex.
