Large claims processors and health care providers use EDI to exchange claim data between systems. When capturing claim data from paper forms with OCR, the extracted data needs to be imported into your claims processing system. Since these systems all support the 837 EDI file format, this is a convenient way to integrate OCR data capture with your claims process without having to build additional data imports.

837 EDI files come in three different flavors:

837-Ql / 837P / Professional Heath Care Claim (HCFA-1500 / CMS-1500)
837-Q2 / 837D / Dental Health Care Claim (J430 / ADA-2012)
837-Q3 / 837I / Institutional Health Care Claim (UB-04 / CMS-1450)
