Which field is designated for external cause of injury codes on the UB-04?

• A. FL 69
• B. FL 71
• C. FL 72 a-c
• D. FL 70

Answer: (C)

External cause of injury codes describe how the injury happened—the circumstances, mechanism, and place of occurrence. On the UB-04 form, this information is captured in the field that's specifically set up to hold external cause data, with subfields for multiple codes. The design allows you to enter up to three external cause codes, which is important when more than one factor contributed to the injury. Because this field is dedicated to external causes, it’s the correct place to record those codes, separate from where diagnoses, procedures, or occurrence details are entered.
