What information is entered in Block 24 I?

Block 24 I on the CMS-1500 form is designated for the "ID Qualifier". This block is used to provide identification information for the service rendered, often denoting which type of identification applies to the provider or the service. The ID qualifier helps insurance companies recognize the types of identifiers being used, which is crucial for processing claims efficiently.

Including the identifier allows insurers to accurately match the services with the correct billing codes, leading to a smoother claims process. It's essential for ensuring that the claims review and payment processes align with the specific requirements of various insurance payers. Other types of information, such as the provider's Social Security number, total charges for services, or patient's insurance details, belong in other sections of the form and do not fit the designated purpose for Block 24 I.
