What does Block 31 require on the CMS-1500 form?

Block 31 on the CMS-1500 form specifically requires the signature of the provider or an authorized representative. This signature is essential because it serves as an attestation that the information on the claim form is accurate and that the services billed have been provided to the patient. The provider's signature indicates that they authorize the release of the medical information necessary for processing the claim, and it affirms responsibility for the treatment rendered.

This block is crucial for ensuring compliance with regulatory standards and facilitating the claims process, which is integral to getting reimbursement from insurance companies. A signature from an unqualified person or a representative from the billing department would not suffice in this context, as claim verification requires the accountability of the healthcare provider who delivered the service.
