Step 3: Explore the File
Once uploaded, you'll see your EDI file broken down into a navigable structure:
Tree View
The default view shows your file as a collapsible tree:
- Interchange (ISA/IEA) — The outer envelope
- Functional Group (GS/GE) — Groups of related transactions
- Transaction Set (ST/SE) — Individual transactions (claims, remittances, etc.)
- Segments — The actual data (CLM, NM1, SVC, etc.)
- Transaction Set (ST/SE) — Individual transactions (claims, remittances, etc.)
- Functional Group (GS/GE) — Groups of related transactions
Click any node to expand it and see what's inside.
Raw View
Switch to Raw View to see segments in their original order, with byte offsets and delimiter highlighting. Useful for troubleshooting parsing issues or comparing with other tools.
Step 4: Find What You're Looking For
Use the Search bar to jump directly to specific data:
- Search by segment — Type
CLMto find all claim segments - Search by value — Type a patient name or claim ID
- Search by element — Type
NM1*ILto find specific qualifier patterns
Click any search result to jump to that location in the file.
Step 5: Understand Segment Details
Click on any segment to see its contents broken down by element:
NM1*IL*1*SMITH*JOHN****MI*12345678901~Becomes:
| Position | Element | Description |
|---|---|---|
| NM101 | IL | Entity Identifier Code: Insured |
| NM102 | 1 | Entity Type: Person |
| NM103 | SMITH | Last Name |
| NM104 | JOHN | First Name |
| NM108 | MI | ID Code Qualifier: Member ID |
| NM109 | 12345678901 | Member ID |
EDI Paisan uses the official X12 implementation guides to label each element with its meaning.
