What information is entered in box 8 of the CMS-1500 form?

Box 8 of the CMS-1500 form is designated for entering the insured’s contact details, specifically the patient’s relationship to the insured. This includes designating whether the patient is the insured, a spouse, dependent, or another relationship. It's essential for the insurance provider and billing personnel to have accurate information regarding the patient's relationship to the insured to process claims correctly.

The form serves to streamline communication between the healthcare provider and the insurance carrier regarding billing and claims, making the correct identification of relationships vital for coverage and payment processing. This box, therefore, focuses on contact details related to the insured and not on medical history, employment status, or identification numbers.
