Which Form Locator is Operating ID?

• A. Form Locator 76
• B. Form Locator 77
• C. Form Locator 78-79
• D. Form Locator 80

Answer: (B)

On UB-04, each Form Locator corresponds to a specific data item on the claim, used to map information to the right data field for processing and reporting. The field designated for identifying the operating department or the surgical team’s internal identifier is the Operating ID. This identifier helps the hospital track which operating unit handled the procedure and supports internal reconciliation of charges with the correct department.

In the standard UB-04 specification, the Operating ID is located at the Form Locator position identified as 77. That’s why this field is used for the Operating ID: it’s the dedicated place to record the internal operating room or department code so the claim can be accurately linked to the proper surgical services. The other Form Locators mentioned (76, 78-79, 80) correspond to different data elements, not the Operating ID, so they aren’t used for this purpose.
