What is the purpose of Block 31 on the CMS-1500 form?

Block 31 on the CMS-1500 form serves the purpose of attesting to the accuracy of the billing information presented on the form. This block is where the provider signs and dates the claim, indicating that they affirm the accuracy and completeness of the information provided. This signature is crucial as it serves as a legal confirmation that the submitted charges correspond to the services rendered and that they are legitimate.

While blocks for the patient’s diagnosis, the date of service, and detailing the services rendered are essential parts of the form, they are covered in different sections or blocks on the CMS-1500. Block 31 specifically focuses on the certification of the accuracy of the information, emphasizing the provider’s responsibility and commitment to truthful billing practices. This aspect is critical in insurance claims processing and ensures a measure of accountability in healthcare billing.
