Which Form Locator is designated for Future Use and is not applicable?

• A. Form Locator 38
• B. Form Locator 42
• C. Form Locator 46
• D. Form Locator 49

Answer: (D)

Some Form Locators on the UB-04 are intentionally reserved for future use or not applicable and should be left blank on standard claims. Form Locator 49 is specifically designated for Future Use and is not applicable, so you do not populate it on typical submissions. This reflects the idea that not every locator carries current data, and using those reserved fields can cause claim errors or misrouting. The other locators in the options correspond to active data fields, which is why they aren’t the correct choice for future-use only.
