The Relational File Layout
is the recommended file layout for data users. It provides more data element information than the Fixed-Width Layout.
The main differences between the formats are the number of diagnoses and procedures provided on a single record and the revenue line detail. The Fixed-Width format provides a maximum of ten diagnoses and six procedures for a single record, whereas the relational format provides all of the diagnoses and procedures on a single record. Another difference is that the Present on Admission (POA) Indicators are only available in the relational format.
The relational format includes the revenue-enhanced data, which includes revenue codes, CPT/HCPCS, units of service and the revenue line charges.
