The 'Diagnosis/Procedure Code Qualifier' uses which Form Locator?

• A. FL63
• B. FL64
• C. FL66
• D. FL67

Answer: (C)

The key idea is that a single field tells the payer which coding system is being used for the codes that follow. On the UB-04, the Diagnosis/Procedure Code Qualifier is located in Form Locator 66, and it applies to the codes that come after in the subsequent fields (diagnosis codes in the following locators and procedure codes in their respective locators). That’s why this locator is the correct place for the qualifier—other locators are designated for different data elements and do not serve as the code qualifier.
