EDI 275 Patient Information


What is EDI 275 A2 Patient Information?

The EDI 275 A2 transaction set is used to communicate individual patient information requests and patient information between separate healthcare entities in a variety of settings to be consistent with confidentiality and use requirements. Patient information consists of demographic, clinical, and other supporting data. The EDI 275 can be sent either solicited or unsolicited. The EDI 275 Patient Information is an EDI transaction designed to carry attachments.

In the Health Insurance Portability and Accountability Act (HIPAA), the term “attachment” refers to the exchange of patient specific medical information or supplemental documentation to support an administrative healthcare transaction. 

Claim attachments, in the context of healthcare EDI, are supplemental electronic documents that provide additional medical information that cannot be accommodated within the claim format. Such as:

  • EEG
  • EKG
  • X-ray image
  • Lab report
  • Health Level 7 (HL7) report
  • Demographic, clinical and other supporting data in an electronic representation that can be attached as payload.

HL7 C-CDA allows for unstructured documents including: 

  • MS WORD 
  • PDF 
  • Plain Text 
  • RTF Text 
  • HTML Text 
  • GIF Image 
  • TIF Image 
  • JPEG Image 
  • PNG Image 

The 275 transaction functionality includes both:

  • Solicited Attachments: Documentation submitted in response to a specific request.
  • Unsolicited Attachments: Documentation known to be needed and submitted at the same time as the claim.
