Electronic Claims File Structure

s

Compliance with the Health Insurance Portability and Accountability Act of 1996 (HIPAA) requires the ANSI ASC X12N 837 Health Care Claims (837) transaction for professional claims and/or encounters to contain specific standardized information. The standardization of health care information allows health care providers to submit 837 electronic files within the NextGen In-line Edits environment.

There are three types of 837 electronic files:

  • Professional (1500 claim forms)
  • Institutional (UB claim forms)
  • Dental ADA

Each type has the same basic electronic file structure. The 837 electronic file is structured to deliver control segments of information, which include:

  • Interchange Control Segments
  • Functional Group Control Segments
  • Transaction Control Segments
  • Loop Control Segments
  • Interchange Acknowledgment Control Segments

Each control segment usually has a beginning header label and an ending trailer label. The table below outlines each of the control segments and their identifying labels.
