Which status must be indicated in Block 8?

Block 8 of the CMS-1500 form is designated for the patient's marital status. This information is relevant for several reasons, such as determining eligibility for certain health benefits or coverage options that may vary based on marital status. Having accurate marital status can also impact how insurance claims are processed and the dependent coverage available to the insured.

Understanding the other options can help clarify why they do not belong in Block 8. Employment terminal status, employment relationship, and patient financial status are not required in this section of the form. Employment-related information is typically recorded elsewhere on the CMS-1500, and financial status may be relevant to different aspects of the claim process but does not directly belong in Block 8.
