What information is provided in Block 26?

Block 26 of the CMS-1500 form is designated for the patient's account number. This block is vital for healthcare providers and insurers as it allows for proper tracking and management of the patient's billing information. By including a unique account number, healthcare providers can efficiently reference a patient's specific case, facilitating correspondence regarding billing and claims processing. The account number may be assigned by the healthcare provider or the practice management system and serves as a crucial identifier in the healthcare billing process.

In this context, while other options such as total charges, provider's name, or claim submission date are important aspects of a health insurance claim, they are not found in Block 26. Each of these fields is located in different blocks, serving separate purposes to ensure accurate and organized handling of a claim. Therefore, the selection of the patient's account number for Block 26 is correct as it aligns with the intended purpose of that specific section of the form.
