Healthcare EDI X12 Parser

Auxtri's free EDI parser helps healthcare AP and supply chain teams visualize and understand EDI 810, 850, 855, and 856 transaction sets. Paste raw EDI data and see every segment and element translated into human-readable labels.

What is an EDI X12 transaction?

EDI (Electronic Data Interchange) X12 is the standard format for exchanging business documents electronically between healthcare organizations and their trading partners. An EDI 810 is the electronic equivalent of a paper invoice, an 850 is a purchase order, an 855 is a PO acknowledgment, and an 856 is an advance ship notice (ASN). These four transaction sets form the backbone of healthcare supply chain procurement — hospitals exchange millions of these documents annually with medical supply distributors like Cardinal Health, McKesson, and Medline.

Frequently Asked Questions

What EDI transaction sets do hospitals use for procurement?
Hospitals primarily use four EDI X12 transaction sets for supply chain procurement: 850 (Purchase Order) to order medical supplies, 855 (PO Acknowledgment) to confirm vendor acceptance, 856 (Advance Ship Notice) to track shipments, and 810 (Invoice) for billing. These flow between the hospital, its GPO (Group Purchasing Organization), and medical supply distributors like Cardinal Health, McKesson, and Medline.
What is the difference between EDI 810 and a paper invoice?
An EDI 810 is the electronic equivalent of a paper invoice. It contains the same information — invoice number, date, line items, quantities, prices, and total — but in a structured X12 format that can be automatically imported into the hospital's ERP system. This eliminates manual data entry, reduces errors, and speeds up the invoice-to-payment cycle. The average hospital processes 140,000+ invoices per year, so automation through EDI is critical.
How do I read raw EDI X12 data?
Raw EDI X12 data uses a simple delimiter-based format. Segments are separated by tildes (~) and elements within a segment are separated by asterisks (*). Each segment starts with a 2-3 character ID (like ISA, BIG, IT1) that identifies its type. This parser translates those cryptic codes into human-readable labels so you can understand what each piece of data represents.
What is an EDI 856 ASN and why does it matter for healthcare?
An EDI 856 (Advance Ship Notice) is sent by the supplier before a shipment arrives at the hospital. It contains details about what was shipped, quantities, tracking information, and packaging. For healthcare organizations, ASNs are critical for receiving dock operations — they allow hospitals to prepare for incoming medical supply deliveries, verify quantities against the original PO, and update inventory systems before the truck arrives.
Is my EDI data sent to a server?
No. Auxtri's EDI parser runs entirely in your browser. Your EDI data never leaves your device — nothing is uploaded, stored, or transmitted. This makes it safe to use with real production EDI documents.
