Which approach for daily claim files submitted to insurance provider?

De-identified files remove personal information to protect patient privacy, but while this is a critical aspect of handling sensitive data, it does not specify the file format used for claims submissions. A de-identified file can still be structured in various formats, including flat files, making it insufficient as a standalone answer to the question.

Multidimensional files involve complex data structures typically used in data warehousing and analytical contexts. While they can be useful for analysis and reporting, they are not practical for daily claim submissions due to their complexity and the need for specialized handling, which is not aligned with the standard process for insurance claims.

Research-identified files are used in studies where patient identities are linked to data for analysis purposes. However, this approach is not suitable for daily claim submissions as it may involve maintaining identifiable information, which conflicts with the privacy requirements of insurance claims processing.
