Where are the name, address, and telephone number of the billing entity entered in the CMS-1500?

The name, address, and telephone number of the billing entity are entered in box 33 of the CMS-1500 form. This box is specifically designated for the billing provider's information, allowing insurers to have a clear point of contact for any questions or clarifications related to the claim. Including accurate details in this section is essential as it facilitates efficient communication between healthcare providers and payers regarding billing inquiries and ensures smooth processing of claims.

Other sections of the CMS-1500 form have specific purposes; for instance, box 25 is used for the provider's Federal Tax Identification Number, box 21 relates to diagnosis codes, and box 17 includes the referring provider's information. Each of these has its distinct role, but when it comes to the billing entity's contact information, box 33 is the correct location.
