In which box is the National Provider Identifier (NPI) number recorded?

The National Provider Identifier (NPI) number is recorded in Box 33 of the CMS-1500 form. This box is designated for the "Provider’s NPI" as part of the claim submission process. It is essential because the NPI serves as a unique identifier for healthcare providers, enabling smooth processing and ensuring that claims are linked to the correct providers for reimbursement purposes.

The importance of accurately entering the NPI in Box 33 cannot be overstated, as it is a critical component for identifying the provider rendering the services documented in the claim. This helps to streamline the administrative aspects of healthcare and allows for easier tracking and management of reimbursement from insurance companies.

The other boxes mentioned pertain to different types of information. For instance, Box 21 is used for diagnoses or conditions, Box 24F is for the rendering provider’s NPI when applicable, and Box 25 is for Federal Tax Identification Number or Social Security Number. Understanding where to place specific identifiers like the NPI is crucial for both compliance and efficient claims processing.
