What information is found in section 1 of the 837P/CMS-1500 form?

Section 1 of the 837P/CMS-1500 form contains the carrier block, which is crucial for identifying the insurance carrier responsible for processing the claim. This section specifies the insurance provider's information, including details such as the name and address of the payer. Having accurate information in the carrier block is essential for ensuring timely processing of the claim and for directing payments appropriately.

While patient demographics, the physician's signature, and diagnosis codes are important components of the claim form, they are located in different sections. Patient demographics typically appear later on the form, while the physician's signature is usually located near the end, and diagnosis codes are included in dedicated areas for coding services rendered. This all highlights the specific role and importance of the carrier block in the overall claim submission process.
