EHCE12 Request Additional Information (2.6)
This is the standard HL7 v2.6 spec, with 0 loops and 14 segment positions, as OpenEDI JSON, an ediFabric C# template and an ediFabric Native model. To change it for a trading partner, customize it in the EDI Spec Builder.
Use the EHCE12 spec in your code
ediFabric .NET
Add the C# template and its common files to your project, or reference the template NuGet package, and read EHCE12 files into TSEHCE12 objects. See ediFabric .NET.
ediFabric Native
Native supports X12 today, and HL7 is coming. When it's available, map version 2.6 to this Native model with set_map to parse EHCE12 files to JSON from Python, Java, C or C#. See ediFabric Native.
OpenEDI
Select Customize in Spec Builder to copy the spec under your own name, change it for your partner, and parse files against it in EdiNation, ediFabric Native or ediFabric Cloud. Read about OpenEDI.
Generate EHCE12 classes in Python, Java, Node.js, Go, Rust or C
The OpenEDI file describes each EHCE12 as JSON. To work with EHCE12 data as typed objects, generate classes from the OpenEDI file in your language; the root class is TSEHCE12. The classes keep the loops, segments, lengths and code lists, but not the EDI data formats. Read more in Generate a class from OpenEDI.
Python: datamodel-code-generator. Node.js: openapi-typescript. Java, Go, Rust and C: OpenAPI Generator.
