Which Form Locator captures the NPI and is Required?

• A. Form Locator 50 - Payer Identification
• B. Form Locator 58 - Insured's Name
• C. Form Locator 56 - NPI - Required
• D. Form Locator 59 - Patient's Relation to Insured

Answer: (C)

NPI on the UB-04 is about correctly identifying the provider filing the claim. The field for the National Provider Identifier is the one that must be populated because it standardizes who is submitting the bill and ties the service to the correct provider in payer systems. This NPI field is required to ensure accurate provider attribution across all payers, support HIPAA-standard electronic submissions, and prevent delays or denials due to missing or unclear provider information. The other fields mentioned—payer identification, insured’s name, and patient’s relation to the insured—serve different purposes (identifying the insurer, the insured, and their relationship) and do not address provider identity.
