Block 32a on the CMS-1500 form is used to record the NPI of which entity?

• A. The facility's address
• B. The facility's phone number
• C. The facility's NPI
• D. The facility's state license number

Answer: (C)

Block 32a is where you enter the facility’s National Provider Identifier—the unique 10-digit NPI assigned to the organization that submits the claim. The NPI is used by payers to identify the billing facility in a standardized way across electronic transactions, helping ensure the claim is linked to the correct entity. This field is specifically for the facility’s identifier, not for the facility’s address, phone number, or state license number, which are captured in other fields. If another provider’s NPI is relevant (such as a rendering physician), that would appear in a different designated field.
