What information is included in Section 1 of the CMS-1500 form?

• A. The address of the insurance carrier.
• B. The patient's contact number.
• C. The provider's NPI.
• D. The referring physician's name.

Answer: (A)

Section 1 focuses on identifying the payer and where the claim should be sent. It includes the insurance carrier’s name and address so the claim can be routed correctly and processed with the correct payer. The carrier’s address is the key detail here because it pins down the exact destination for submission and any correspondence. Other items listed would appear in different parts of the form: a patient’s contact number is entered in the patient demographic area, the provider’s NPI is recorded in the provider information section, and the referring physician’s name goes in the referring/provider fields. Understanding that Section 1 sets up the payer and submission routing helps explain why the carrier’s address is the best fit.
