EDI 837 claim file format

EDI 837 File Format Types

The healthcare EDI 837 transaction set provides the HIPAA 5010 standard requirements EDI capable organization to submit claims.  The file contains information about a patient claim and is submitted to healthcare plans for payment. As of March 31, 2012, healthcare providers should be compliant with version 5010 of the HIPAA EDI standards.  One of the major changes from 4010 to 5010 is expanding the ICD codes.  The ICD9 codes in 4010 were expanded to the 5010 ICD10 diagnostic codes. We recomend utilizing our free EDI Viewer to easly navigate claim files and detect validation errors.
